organic farming

{{Main|History of organic farming}}

Agriculture was practiced for thousands of years without the use of artificial chemicals. Artificial fertilizers were first developed during the mid-19th century. These early fertilizers were cheap, powerful, and easy to transport in bulk. Similar advances occurred in chemical pesticides in the 1940s, leading to the decade being referred to as the "pesticide era".{{cite book|last=Horne|first=Paul Anthony|title=Integrated pest management for crops and pastures|year=2008|publisher=CSIRO Publishing|isbn=978-0-643-09257-0|page=2|url={{google books |plainurl=y |id=dhO4HAQbNU8C|page=2}}}} These new agricultural techniques, while beneficial in the short-term, had serious longer-term side-effects, such as soil compaction, erosion, and declines in overall soil fertility, along with health concerns about toxic chemicals entering the food supply.{{Cite book |year=2007 |last=Stinner, D.H |chapter=The Science of Organic Farming |editor=William Lockeretz |title=Organic Farming: An International History |publisher=Oxfordshire, UK & Cambridge, Massachusetts: CAB International (CABI) |chapter-url={{google books |plainurl=y |id=25QnL3-njZQC%22Organic}} |access-date=30 April 2013|isbn=978-1-84593-289-3}}{{rp|10}} In the late 1800s and early 1900s, soil biology scientists began to seek ways to remedy these side effects while still maintaining higher production.

In 1924 Rudolf Steiner gave a series of eight lectures on agriculture with a focus on influences of the moon, planets, non-physical beings and elemental forces.Paull, John (2013) [http://orgprints.org/22491/17/22491.pdf "Koberwitz (Kobierzyce); In the footsteps of Rudolf Steiner'"], Journal of Bio-Dynamics Tasmania, 109 (Autumn), pp. 7-11.Paull, John (2013) [http://orgprints.org/22976/27/22976.pdf "Breslau (Wrocław): In the footsteps of Rudolf Steiner"], Journal of Bio- Dynamics Tasmania, 110:10-15. They were held in response to a request by adherent farmers who noticed degraded soil conditions and a deterioration in the health and quality of crops and livestock resulting from the use of chemical fertilizers.Diver (1999), [http://attra.ncat.org/attra-pub/biodynamic.html#intro "Introduction"] {{Webarchive|url=https://web.archive.org/web/20110526054008/http://attra.ncat.org/attra-pub/biodynamic.html#intro |date=26 May 2011 }}. The lectures were published in November 1924; the first English translation appeared in 1928 as The Agriculture Course.{{cite journal |last=Paull |first=John |year=2011 |url=http://www.jsrp.ro/content/JSRP-Nr3_PAULL |title=The secrets of Koberwitz: the diffusion of Rudolf Steiner's agriculture course and the founding of biodynamic agriculture |journal=Journal of Social Research & Policy |volume=2 |issue=1 |pages=19–29 |access-date=6 March 2016 |url-status=live |archive-url=https://web.archive.org/web/20160308223858/http://www.jsrp.ro/content/JSRP-Nr3_PAULL |archive-date=8 March 2016}}

In July 1939, Ehrenfried Pfeiffer, the author of the standard work on biodynamic agriculture (Bio-Dynamic Farming and Gardening),{{cite journal |author=Paull, John |year=2011 |title=Biodynamic Agriculture: The Journey from Koberwitz to the World, 1924-1938|url=http://ora.ox.ac.uk/objects/uuid:304a24bf-3961-4798-b13c-9e0a1e2aa339|journal=Journal of Organic Systems |volume=6 |issue=1 |pages=27–41}} came to the UK at the invitation of Walter James, 4th Baron Northbourne as a presenter at the Betteshanger Summer School and Conference on Biodynamic Farming at Northbourne's farm in Kent.Paull, John (2011) [http://orgprints.org/19511/1/Paull2011BetteshangerJOS.pdf "The Betteshanger Summer School: Missing link between biodynamic agriculture and organic farming"], Journal of Organic Systems, 6(2):13-26. One of the chief purposes of the conference was to bring together the proponents of various approaches to organic agriculture in order that they might cooperate within a larger movement. Howard attended the conference, where he met Pfeiffer.Ehrenfried E. Pfeiffer, [http://journeytoforever.org/farm_library/howard_memorial.html Sir Albert Howard's Deed for Science] In the following year, Northbourne published his manifesto of organic farming, Look to the Land, in which he coined the term "organic farming". The Betteshanger conference has been described as the 'missing link' between biodynamic agriculture and other forms of organic farming.

In 1940, Howard published his An Agricultural Testament. In this book he adopted Northbourne's terminology of "organic farming".Paull, John (2006) [http://orgprints.org/10138/1/10138.pdf The Farm as Organism: The Foundational Idea of Organic Agriculture] Elementals ~ Journal of Bio-Dynamics Tasmania 83:14–18 Howard's work spread widely, and he became known as the "father of organic farming" for his work in applying scientific knowledge and principles to various traditional and natural methods.{{rp|45}} In the United States J. I. Rodale, who was keenly interested both in Howard's ideas and in biodynamics, founded in the 1940s both a working organic farm for trials and experimentation, The Rodale Institute, and Rodale, Inc., in Emmaus, Pennsylvania, to teach and advocate organic methods to the wider public. These became important influences on the spread of organic agriculture. Further work was done by Lady Eve Balfour (the Haughley Experiment) in the United Kingdom, and many other places across the world.

The term "eco-agriculture" was coined in 1970 by Charles Walters, founder of Acres Magazine, to describe agriculture which does not use "man-made molecules of toxic rescue chemistry", effectively another name for organic agriculture.{{cite web |url=http://www.acresusa.com/eco-agriculture/ |title=What is Eco-Agriculture? |publisher=Acres, USA |access-date=15 October 2019 |archive-date=23 April 2018 |archive-url=https://web.archive.org/web/20180423102152/https://www.acresusa.com/eco-agriculture |url-status=dead }}

Increasing environmental awareness in the general population in modern times has transformed the originally supply-driven organic movement to a demand-driven one. Premium prices and some government subsidies attracted farmers. In the developing world, many producers farm according to traditional methods that are comparable to organic farming, but not certified, and that may not include the latest scientific advancements in organic agriculture. In other cases, farmers in the developing world have converted to modern organic methods for economic reasons.Paull, John [http://orgprints.org/10949/01/10949.pdf "China's Organic Revolution"], Journal of Organic Systems (2007) 2 (1): 1-11.

The use of "organic" popularized by Howard and Rodale refers more narrowly to the use of organic matter derived from plant compost and animal manures to improve the humus content of soils, grounded in the work of early soil scientists who developed what was then called "humus farming". Since the early 1940s the two camps have tended to merge.{{cite web|last=Nayler|first=Justin|title=Second Thoughts About Organic Agriculture|url=http://www.soilandhealth.org/01aglibrary/Second.Thoughts.pdf|publisher=Soil And Health Library|access-date=11 May 2014|archive-url=https://web.archive.org/web/20140801061226/http://www.soilandhealth.org/01aglibrary/Second.Thoughts.pdf|archive-date=1 August 2014|url-status=dead}}{{cite web|last=Diver|first=Steve|title=Controlled Microbial Composting and Humus Management: Luebke Compost|url=http://www.ibiblio.org/steved/Luebke/Luebke-compost2.html|access-date=11 May 2014}}

Biodynamic agriculturists, on the other hand, used the term "organic" to indicate that a farm should be viewed as a living organism,{{rp|17–19}} in the sense of the following quotation:

{{blockquote|1=An organic farm, properly speaking, is not one that uses certain methods and substances and avoids others; it is a farm whose structure is formed in imitation of the structure of a natural system that has the integrity, the independence and the benign dependence of an organism

| 2=Wendell Berry, "The Gift of Good Land"}}

They based their work on Steiner's spiritually-oriented alternative biodynamic agriculture which includes various esoteric concepts.

{{blockquote|"Organic agriculture is a production system that sustains the health of soils, ecosystems and people. It relies on ecological processes, biodiversity and cycles adapted to local conditions, rather than the use of inputs with adverse effects.

Organic farming methods combine scientific knowledge of ecology and some modern technology with traditional farming practices based on naturally occurring biological processes. Organic farming methods are studied in the field of agroecology. While conventional agriculture uses synthetic pesticides and water-soluble synthetically purified fertilizers, organic farmers are restricted by regulations to using natural pesticides and fertilizers. An example of a natural pesticide is pyrethrin, which is found naturally in the Chrysanthemum flower. The principal methods of organic farming include crop rotation, green manures and compost, biological pest control, and mechanical cultivation. These measures use the natural environment to enhance agricultural productivity: legumes are planted to fix nitrogen into the soil, natural insect predators are encouraged, crops are rotated to confuse pests and renew soil, and natural materials such as potassium bicarbonateFiBL (2006) [http://www.betriebsmittelliste.ch/fileadmin/documents/de/hifu/stellungnahmen/potassium_bicarbonate_organic.pdf Use of potassium bicarbonate as a fungicide in organic farming] {{Webarchive|url=https://web.archive.org/web/20140111033236/http://www.betriebsmittelliste.ch/fileadmin/documents/de/hifu/stellungnahmen/potassium_bicarbonate_organic.pdf |date=11 January 2014 }} and mulches are used to control disease and weeds. Genetically modified seeds and animals are excluded.

While organic is fundamentally different from conventional because of the use of carbon-based fertilizers compared with highly soluble synthetic based fertilizers and biological pest control instead of synthetic pesticides, organic farming and large-scale conventional farming are not entirely mutually exclusive. Many of the methods developed for organic agriculture have been borrowed by more conventional agriculture. For example, Integrated Pest Management is a multifaceted strategy that uses various organic methods of pest control whenever possible, but in conventional farming could include synthetic pesticides only as a last resort.{{cite web | title =Integrated Pest Management | publisher =U.S. Environmental Protection Agency | url =http://www.epa.gov/oecaagct/tipm.html | access-date =1 January 2013 }} Examples of beneficial insects that are used in organic farming include ladybugs and lacewings, both of which feed on aphids. The use of IPM lowers the possibility of pest developing resistance to pesticides that are applied to crops.

Organic farming encourages crop diversity by promoting polyculture (multiple crops in the same space). Planting a variety of vegetable crops supports a wider range of beneficial insects, soil microorganisms, and other factors that add up to overall farm health. Crop diversity helps the environment to thrive and protects species from going extinct.Fargione J, and D Tilman. 2002.

Agroecology is a scientific discipline that uses ecological theory to study, design, manage, and evaluate agricultural systems that are productive and resource-conserving, and that are also culturally sensitive, socially just, and economically viable.{{cite web |title=Diversity: diversification is key to agroecological transitions to ensure food security and nutrition while conserving, protecting and enhancing natural resources |url=https://www.fao.org/agroecology/knowledge/10-elements/diversity/en/ |website=Fao |publisher=Food and organization of the united nations |access-date=15 November 2023}}

Incorporating crop diversity into organic farming practices can have several benefits. For instance, it can help to increase soil fertility by promoting the growth of beneficial soil microorganisms. It can also help to reduce pest and disease pressure by creating a more diverse and resilient agroecosystem.{{cite web |title=Why Diversify? |url=https://www.sare.org/publications/diversifying-cropping-systems/why-diversify/ |website=SARE |access-date=15 November 2023}} Furthermore, crop diversity can help to improve the nutritional quality of food by providing a wider range of essential nutrients.{{cite web |title=Organic agriculture and its benefits for climate and biodiversity |url=https://www.organicseurope.bio/content/uploads/2022/04/IFOAMEU_advocacy_organic-benefits-for-climate-and-biodiversity_2022.pdf?dd |website=Organics Europe |access-date=15 November 2023}}

Organic farming relies more heavily on the natural breakdown of organic matter than the average conventional farm, using techniques like green manure and composting, to replace nutrients taken from the soil by previous crops. This biological process, driven by microorganisms such as mycorrhiza and earthworms, releases nutrients available to plants throughout the growing season. Farmers use a variety of methods to improve soil fertility, including crop rotation, cover cropping, reduced tillage, and application of compost. By reducing fuel-intensive tillage, less soil organic matter is lost to the atmosphere. This has an added benefit of carbon sequestration, which reduces greenhouse gases and helps reverse climate change. Reducing tillage may also improve soil structure and reduce the potential for soil erosion.

Plants need a large number of nutrients in various quantities to flourish. Supplying enough nitrogen and particularly synchronization, so that plants get enough nitrogen at the time when they need it most, is a challenge for organic farmers.{{Cite journal|vauthors=Watson CA, Atkinson D, Gosling P, Jackson LR, Rayns FW | title = Managing soil fertility in organic farming systems | year = 2002 | journal = Soil Use and Management | pages = 239–247| volume = 18 | doi = 10.1111/j.1475-2743.2002.tb00265.x | bibcode = 2002SUMan..18S.239W | s2cid = 36782412 | url = http://orgprints.org/8060/2/Watson_orgprints_8060.pdf }} [http://orgprints.org/8060/ Preprint with free full-text]. Crop rotation and green manure ("cover crops") help to provide nitrogen through legumes (more precisely, the family Fabaceae), which fix nitrogen from the atmosphere through symbiosis with rhizobial bacteria. Intercropping, which is sometimes used for insect and disease control, can also increase soil nutrients, but the competition between the legume and the crop can be problematic and wider spacing between crop rows is required. Crop residues can be ploughed back into the soil, and different plants leave different amounts of nitrogen, potentially aiding synchronization. Organic farmers also use animal manureand certain processed fertilizers, such as seed meal and various mineral powders such as rock phosphate and green sand, a naturally occurring form of potash that provides potassium. In some cases, pH may need to be amended. Natural pH amendments include lime and sulfur, but in the U.S. some compounds, such as iron sulfate, aluminum sulfate, magnesium sulfate, and soluble boron products are allowed in organic farming.{{Rp|43}}

Mixed farms with both livestock and crops can operate as ley farms, whereby the land gathers fertility through growing nitrogen-fixing forage grasses, such as white clover or alfalfa,

and grows cash crops or cereals when fertility is established. Farms without livestock ("stockless") may find it more difficult to maintain soil fertility and may rely more on external inputs, such as imported manure, as well as grain legumes and green manures, although grain legumes may fix limited nitrogen because they are harvested. Horticultural farms that grow fruits and vegetables in protected conditions often rely even more on external inputs. Manure is very bulky and is often not cost-effective to transport more than a short distance from the source. Manure for organic farms may become scarce if a sizable number of farms become organically managed.

Organic weed management promotes weed suppression, rather than weed elimination, by enhancing crop competition and phytotoxic effects on weeds.Kathleen Delate and Robert Hartzler. 2003. [http://www.extension.iastate.edu/Publications/PM1883.pdf Weed Management for Organic Farmers]. Iowa State University Extension Bulletin 1883. Organic farmers integrate cultural, biological, mechanical, physical and chemical tactics to manage weeds without synthetic herbicides.

Organic standards require rotation of annual crops,Staff, United Nations Conference on Trade and Development. [http://193.194.138.42/en/Sustainability-Claims-Portal/Discussion-Forum/Organic-Standards/ Organic Standards] {{Webarchive|url=https://web.archive.org/web/20150606214740/http://193.194.138.42/en/Sustainability-Claims-Portal/Discussion-Forum/Organic-Standards/ |date=6 June 2015 }} meaning that a single crop cannot be grown in the same location without a different, intervening crop. Organic crop rotations frequently include weed-suppressive cover crops and crops with dissimilar life cycles to discourage weeds associated with a particular crop. Research is ongoing to develop organic methods to promote the growth of natural microorganisms that suppress the growth or germination of common weeds.{{cite journal | last1 = Kremer | first1 = Robert J. | last2 = Li | first2 = Jianmei | year = 2003 | title = Developing weed-suppressive soils through improved soil quality management | url = http://naldc.nal.usda.gov/download/11123/PDF | journal = Soil & Tillage Research | volume = 72 | issue = 2 | pages = 193–202 | doi = 10.1016/s0167-1987(03)00088-6 | bibcode = 2003STilR..72..193K | access-date = 3 February 2013 | archive-date = 3 March 2016 | archive-url = https://web.archive.org/web/20160303172306/http://naldc.nal.usda.gov/download/11123/PDF | url-status = dead }}

Other cultural practices used to enhance crop competitiveness and reduce weed pressure include selection of competitive crop varieties, high-density planting, tight row spacing, and late planting into warm soil to encourage rapid crop germination.

Some naturally sourced chemicals are allowed for herbicidal use. These include certain formulations of acetic acid (concentrated vinegar), corn gluten meal, and essential oils. A few selective bioherbicides based on fungal pathogens have also been developed. At this time, however, organic herbicides and bioherbicides play a minor role in the organic weed control toolbox.

Weeds can be controlled by grazing. For example, geese have been used successfully to weed a range of organic crops including cotton, strawberries, tobacco, and corn,Glenn Geiger and Harold Biellier. 1993.

Organisms aside from weeds that cause problems on farms include arthropods (e.g., insects, mites), nematodes, fungi and bacteria. Practices include, but are not limited to:

Examples of predatory beneficial insects include minute pirate bugs, big-eyed bugs, and to a lesser extent ladybugs (which tend to fly away), all of which eat a wide range of pests. Lacewings are also effective, but tend to fly away. Praying mantis tend to move more slowly and eat less heavily. Parasitoid wasps tend to be effective for their selected prey, but like all small insects can be less effective outdoors because the wind controls their movement. Predatory mites are effective for controlling other mites.{{Rp|66–90}}

Naturally derived insecticides allowed for use on organic farms include Bacillus thuringiensis (a bacterial toxin), pyrethrum (a chrysanthemum extract), spinosad (a bacterial metabolite), neem (a tree extract) and rotenone (a legume root extract). Fewer than 10% of organic farmers use these pesticides regularly; a 2003 survey found that only 5.3% of vegetable growers in California use rotenone while 1.7% use pyrethrum.{{Cite journal |last1=Lotter |first1=D. |year=2003 |url=http://donlotter.net/lotter_organicag.pdf |title=Organic Agriculture |journal=Journal of Sustainable Agriculture |volume=21 |issue=4 |doi=10.1300/J064v21n04_06 |page=59 |bibcode=2003JSusA..21d..59L |s2cid=216090323 |access-date=13 February 2008 |archive-date=8 July 2018 |archive-url=https://web.archive.org/web/20180708123123/http://donlotter.net/lotter_organicag.pdf |url-status=dead }}{{rp|26}} These pesticides are not always more safe or environmentally friendly than synthetic pesticides and can cause harm.Gillman J.

Raising livestock and poultry, for meat, dairy and eggs, is another traditional farming activity that complements growing. Organic farms attempt to provide animals with natural living conditions and feed. Organic certification verifies that livestock are raised according to the USDA organic regulations throughout their lives.{{Cite web|url=https://www.ams.usda.gov/?dDocName=STELPRDC5102526|title=Agricultural Marketing Service|website=www.ams.usda.gov|access-date=2018-12-17}} These regulations include the requirement that all animal feed must be certified organic.

Organic livestock may be, and must be, treated with medicine when they are sick, but drugs cannot be used to promote growth, their feed must be organic, and they must be pastured.FAO [http://www.fao.org/docs/eims/upload/230124/CXg_032e.pdf Guidelines for the Production, Processing, Labelling and Marketing of Organically Produced Foods (Gl 32 – 1999, Rev. 1 – 2001)] {{Webarchive|url=https://web.archive.org/web/20210224181750/http://www.fao.org/docs/eims/upload/230124/CXg_032e.pdf |date=24 February 2021 }}{{rp|19ff}}{{Cite web|url=https://www.ams.usda.gov/?acct=nopgeninfo&leftNav=NationalOrganicProgram&navID=OrganicStandardslinkNOPConsumers&page=NOPOrganicStandards&resultType=&rightNav1=OrganicStandardslinkNOPConsumers&template=TemplateN&topNav=|title=Home | Agricultural Marketing Service|website=www.ams.usda.gov}}

Also, horses and cattle were once a basic farm feature that provided labour, for hauling and plowing, fertility, through recycling of manure, and fuel, in the form of food for farmers and other animals. While today, small growing operations often do not include livestock, domesticated animals are a desirable part of the organic farming equation, especially for true sustainability, the ability of a farm to function as a self-renewing unit.

{{Main|Genetically modified crops|Genetically modified food|Genetically modified food controversies}}

A key characteristic of organic farming is the exclusion of genetically engineered plants and animals. On 19 October 1998, participants at IFOAM's 12th Scientific Conference issued the Mar del Plata Declaration, where more than 600 delegates from over 60 countries voted unanimously to exclude the use of genetically modified organisms in organic food production and agriculture.

Although opposition to the use of any transgenic technologies in organic farming is strong, agricultural researchers Luis Herrera-Estrella and Ariel Alvarez-Morales continue to advocate integration of transgenic technologies into organic farming as the optimal means to sustainable agriculture, particularly in the developing world.{{Cite journal| volume=2 |date=April 2001 |author1=Luis Herrera-Estrella |author2=Ariel Alvarez-Morales |title=Genetically modified crops: hope for developing countries? |pages=256–258| doi= 10.1093/embo-reports/kve075 |journal=EMBO Reports |pmid=11306538 |issue=4 |pmc=1083872}} Organic farmer Raoul Adamchak and geneticist Pamela Ronald write that many agricultural applications of biotechnology are consistent with organic principles and have significantly advanced sustainable agriculture.{{Cite book|publisher=Oxford University Press |date=April 2018 |author1=Pamela Ronald |author2=Raoul Adamchak |title=Tomorrow's Table: Organic Farming, Genetics and the Future of Food|isbn=978-0199342082 }}

Although GMOs are excluded from organic farming, there is concern that the pollen from genetically modified crops is increasingly penetrating organic and heirloom seed stocks, making it difficult, if not impossible, to keep these genomes from entering the organic food supply. Differing regulations among countries limits the availability of GMOs to certain countries, as described in the article on regulation of the release of genetic modified organisms.

Organic farmers use a number of traditional farm tools to do farming, and may make use of agricultural machinery in similar ways to conventional farming. In the developing world, on small organic farms, tools are normally constrained to hand tools and diesel powered water pumps.

{{Main|Organic certification}}

Standards regulate production methods and in some cases final output for organic agriculture. Standards may be voluntary or legislated. As early as the 1970s private associations certified organic producers. In the 1980s, governments began to produce organic production guidelines. In the 1990s, a trend toward legislated standards began, most notably with the 1991 EU-Eco-regulation developed for European Union,{{Cite web|url=https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=LEGISSUM:l21118|title=Organically grown agricultural products and foodstuffs|website=EUR-Lex}} which set standards for 12 countries, and a 1993 UK program. The EU's program was followed by a Japanese program in 2001, and in 2002 the U.S. created the National Organic Program (NOP).USDA [http://www.ams.usda.gov/nop/NOP/standards.html NOP Program Standards]. Retrieved 2 April 2008. As of 2007 over 60 countries regulate organic farming (IFOAM 2007:11). In 2005 IFOAM created the Principles of Organic Agriculture, an international guideline for certification criteria.IFOAM. (2005). [http://www.ifoam.org/about_ifoam/standards/norms.html The IFOAM Norms] {{Webarchive|url=https://web.archive.org/web/20060210095156/http://www.ifoam.org/about_ifoam/standards/norms.html |date=10 February 2006 }} Typically the agencies accredit certification groups rather than individual farms.

Production materials used for the creation of USDA Organic certified foods require the approval of a NOP accredited certifier.

EU-organic production-regulation on "organic" food labels define "organic" primarily in terms of whether "natural" or "artificial" substances were allowed as inputs in the food production process.{{Cite journal|date=2017-04-01|title=What is this thing called organic? – How organic farming is codified in regulations |journal=Food Policy |volume=68 |pages=10–20 |doi=10.1016/j.foodpol.2016.12.009 |issn=0306-9192 |last1=Seufert |first1=Verena |last2=Ramankutty |first2=Navin |last3=Mayerhofer |first3=Tabea |hdl=2429/70221 |hdl-access=free}}

If raw animal manure is used, 120 days must pass before the crop is harvested if the final product comes into direct contact with the soil. For products that do not directly contact soil, 90 days must pass prior to harvest.{{cite web|url=http://ecfr.gpoaccess.gov/cgi/t/text/text-idx?c=ecfr;sid=11fd57b422b6314d866dc4b02f1a101d;rgn=div5;view=text;node=7:3.1.1.9.30;idno=7;cc=ecfr|title=National Organic Program Regulations|access-date=27 November 2007|archive-url=https://web.archive.org/web/20071211185453/http://ecfr.gpoaccess.gov/cgi/t/text/text-idx?c=ecfr;sid=11fd57b422b6314d866dc4b02f1a101d;rgn=div5;view=text;node=7:3.1.1.9.30;idno=7;cc=ecfr|archive-date=11 December 2007|url-status=dead}}

In the US, the Organic Food Production Act of 1990 (OFPA) as amended, specifies that a farm can not be certified as organic if the compost being used contains any synthetic ingredients. The OFPA singles out commercially blended fertilizers [composts] disallowing the use of any fertilizer [compost] that contains prohibited materials.{{Cite web|url=https://www.congress.gov/bill/101st-congress/senate-bill/2108/text|title=Organic Food Production Act of 1990|website=Congress.gov|date=22 March 1990}}

The economics of organic farming, a subfield of agricultural economics, encompasses the entire process and effects of organic farming in terms of human society, including social costs, opportunity costs, unintended consequences, information asymmetries, and economies of scale.

Labour input, carbon and methane emissions, energy use, eutrophication, acidification, soil quality, effect on biodiversity, and overall land use vary considerably between individual farms and between crops, making general comparisons between the economics of organic and conventional agriculture difficult.{{Cite journal|url=https://ourworldindata.org/is-organic-agriculture-better-for-the-environment|title=Is organic really better for the environment than conventional agriculture?|journal=Our World in Data|date=2 February 2024 |last1=Ritchie |first1=Hannah |last2=Roser |first2=Max }}Clark, M., & Tilman, D.

The gap is particularly important for wheat, with a yield ranging between 40% (Germany) and 85% (Italy) of conventional yields. The gap for organic maize yields and milk yields is lower, but may still represent a strong disincentive if not compensated by higher prices. Lower yields seem however to be counterbalanced by higher producer prices. In Germany, organic wheat producers received up to 150% price premium over conventional prices.

Australia's organic land area has increased at a rate of 16.5% per annum for the past eighteen years.

In 2013, the number of organic producers grew by almost 270,000, or more than 13%. By 2014, there were a reported 2.3 million organic producers in the world. Most of the total global increase took place in the Philippines, Peru, China, and Thailand.

The organic farming systems used 20 – 56% less energy to produce a crop unit and per land area this difference was 36 – 53%. In spite of the considerably lower pesticide input the quality of organic products was hardly discernible from conventional analytically and even came off better in food preference trials and picture creating methods."Fliessbach, et al.

In the United States, organic farming has been shown to be 2.7 to 3.8 times more profitable for the farmer than conventional farming when prevailing price premiums are taken into account.{{Cite journal|last=Moyer|first=Jeff|date=2013|title=Perspective on Rodale Institute's Farming Systems Trial|journal=Crop Management|volume=12|pages=1–3|doi=10.1094/CM-2013-0429-03-PS}} Globally, organic farming is 22–35% more profitable for farmers than conventional methods, according to a 2015 meta-analysis of studies conducted across five continents.{{Cite journal|last1=Crowder|first1=David W.|last2=Reganold |first2=John P.|date=16 June 2015|title=Financial competitiveness of organic agriculture on a global scale|journal=Proceedings of the National Academy of Sciences|volume=112|issue=24|pages=7611–7616|doi=10.1073/pnas.1423674112|issn=0027-8424|pmc=4475942 |pmid=26034271|bibcode=2015PNAS..112.7611C|doi-access=free}}

The profitability of organic agriculture can be attributed to a number of factors. First, organic farmers do not rely on synthetic fertilizer and pesticide inputs, which can be costly. In addition, organic foods currently enjoy a price premium over conventionally produced foods, meaning that organic farmers can often get more for their yield.

The price premium for organic food is an important factor in the economic viability of organic farming. In 2013 there was a 100% price premium on organic vegetables and a 57% price premium for organic fruits. These percentages are based on wholesale fruit and vegetable prices, available through the United States Department of Agriculture's Economic Research Service.{{Cite web|url=http://www.ers.usda.gov/data-products/organic-prices.aspx|title=USDA Economic Research Service - Organic Prices|last=Greene|first=Catherine|website=www.ers.usda.gov|access-date=25 March 2016}} Price premiums exist not only for organic versus nonorganic crops, but may also vary depending on the venue where the product is sold: farmers' markets, grocery stores, or wholesale to restaurants. For many producers, direct sales at farmers' markets are most profitable because the farmer receives the entire markup, however this is also the most time and labour-intensive approach.{{Cite book|title=Understanding Organic Pricing and Costs of Production|last=Post|first=Emily|publisher=NCAT|year=2012}}

There have been signs of organic price premiums narrowing in recent years, which lowers the economic incentive for farmers to convert to or maintain organic production methods.{{Cite journal|last1=McBride|first1=William D.|last2=Greene |first2=Catherine R.|date=2013|title=Organic Data and Research from the ARMS Survey: Findings on Competitiveness of the Organic Soybean Sector|journal=Crop Management|volume=12|pages=1–11|doi=10.1094/CM-2013-0429-04-RS}} Data from 22 years of experiments at the Rodale Institute found that, based on the current yields and production costs associated with organic farming in the United States, a price premium of only 10% is required to achieve parity with conventional farming. A separate study found that on a global scale, price premiums of only 5-7% were needed to break even with conventional methods. Without the price premium, profitability for farmers is mixed.{{rp|11}}

For markets and supermarkets organic food is profitable as well, and is generally sold at significantly higher prices than non-organic food.{{cite news|url=https://www.nytimes.com/2008/04/18/business/18organic.html?pagewanted=all&_r=0|title=Sticker Shock in the Organic Aisles |last=Martin|first=Andrew|author2=Kim Severson |date=18 April 2008|newspaper=New York Times|access-date=5 March 2015}}

It has generally been found that the labour input per unit of yield was higher for organic systems compared with conventional production.

Most sales are concentrated in developed nations. In 2008, 69% of Americans claimed to occasionally buy organic products, down from 73% in 2005. One theory for this change was that consumers were substituting "local" produce for "organic" produce.CNN.

The USDA requires that distributors, manufacturers, and processors of organic products be certified by an accredited state or private agency.{{Cite web|url=http://www.ers.usda.gov/media/192533/vgs32901.pdf|title=Using Vertically Coordinated Relationships To Overcome Tight Supply in the Organic Market|last1=Dimitri|first1=Carolyn|last2=Oberholtzer|first2=Lydia|date=October 2008|publisher=USDA|access-date=2016-04-19|archive-url=https://web.archive.org/web/20160518010404/http://www.ers.usda.gov/media/192533/vgs32901.pdf|archive-date=18 May 2016|url-status=dead}} In 2007, there were 3,225 certified organic handlers, up from 2,790 in 2004.{{Cite web|url=http://www.ers.usda.gov/publications/pub-details/?pubid=44432|title=Marketing U.S. Organic Foods: Recent Trends From Farms to Consumers (EIB-58)|first1=Carolyn|last1=Dimitri|first2=Lydia|last2=Oberholtzer|website=Economic Research Service|date=September 2009}}

Organic handlers are often small firms; 48% reported sales below $1 million annually, and 22% between $1 and $5 million per year.{{Cite web|url=http://www.ers.usda.gov/amber-waves/2008-september/us-organic-handlers-mostly-small,-focus-on-fruit-and-vegetables.aspx#.VxTnWRMrI6h|title=USDA Economic Research Service - U.S. Organic Handlers Mostly Small, Focus on Fruit and Vegetables |last1=Dimitri |first1=Carolyn |last2=Oberholtzer |first2=Lydia |website=www.ers.usda.gov|access-date=2016-04-19|archive-url=https://web.archive.org/web/20160426205152/http://www.ers.usda.gov/amber-waves/2008-september/us-organic-handlers-mostly-small,-focus-on-fruit-and-vegetables.aspx#.VxTnWRMrI6h|archive-date=26 April 2016|url-status=dead}} Smaller handlers are more likely to sell to independent natural grocery stores and natural product chains whereas large distributors more often market to natural product chains and conventional supermarkets, with a small group marketing to independent natural product stores. Some handlers work with conventional farmers to convert their land to organic with the knowledge that the farmer will have a secure sales outlet. This lowers the risk for the handler as well as the farmer. In 2004, 31% of handlers provided technical support on organic standards or production to their suppliers and 34% encouraged their suppliers to transition to organic. Smaller farms often join in cooperatives to market their goods more effectively.

93% of organic sales are through conventional and natural food supermarkets and chains, while the remaining 7% of U.S. organic food sales occur through farmers' markets, foodservices, and other marketing channels.{{Cite web|url=http://www.ers.usda.gov/topics/natural-resources-environment/organic-agriculture/organic-market-overview.aspx|title=USDA Economic Research Service - Organic Market Overview|last=Greene|first=Catherine|website=www.ers.usda.gov|access-date=2016-04-19|archive-date=26 August 2014|archive-url=https://web.archive.org/web/20140826120318/http://www.ers.usda.gov/topics/natural-resources-environment/organic-agriculture/organic-market-overview.aspx|url-status=dead}}

In the 2012 Census, direct-to-consumer sales equalled $1.3 billion, up from $812 million in 2002, an increase of 60 percent. The number of farms that utilize direct-to-consumer sales was 144,530 in 2012 in comparison to 116,733 in 2002.{{Cite web|url=http://sustainableagriculture.net/blog/2012-census-organic-local/|title=2012 Census Drilldown: Organic and Local Food {{!}} National Sustainable Agriculture Coalition|website=sustainableagriculture.net|date=16 May 2014|access-date=2016-04-19}} Direct-to-consumer sales include farmers' markets, community supported agriculture (CSA), on-farm stores, and roadside farm stands.

Organic production is more labour-intensive than conventional production.Staff, FAO [http://www.fao.org/organicag/oa-faq/oa-faq5/en/ Organic Agriculture FAQ] Increased labour cost is one factor that contributes to organic food being more expensive. Organic farming's increased labour requirements can be seen in a good way providing more job opportunities for people. The 2011 UNEP Green Economy Report suggests that "[a]n increase in investment in green agriculture is projected to lead to growth in employment of about 60 per cent compared with current levels" and that "green agriculture investments could create 47 million additional jobs compared with BAU2 over the next 40 years".Citation used: UNEP, 2011, Towards a Green Economy: Pathways to Sustainable Development and Poverty Eradication, www.unep.org/greeneconomy

Much of the growth in women labour participation in agriculture is outside the "male dominated field of conventional agriculture". Organic farming has a greater percentage of women working in the farms with 21% compared to farming in general with 14%.

In 2007 the United Nations Food and Agriculture Organization (FAO) said that organic agriculture often leads to higher prices and hence a better income for farmers, so it should be promoted. However, FAO stressed that organic farming could not feed the current human population, much less the larger future population. Both data and models showed that organic farming was far from sufficient. Therefore, chemical fertilizers were needed to avoid hunger.{{cite web|url=http://www.fao.org/newsroom/en/news/2007/1000726/index.html|title=Organic agriculture can contribute to fighting hunger - But chemical fertilizers needed to feed the world|website=Food and Agriculture Organization|date=2007-12-10|access-date=|archive-date=2 May 2013|archive-url=https://web.archive.org/web/20130502120829/http://www.fao.org/newsroom/en/news/2007/1000726/index.html|url-status=dead}} Others have argued that organic farming is particularly well-suited to food-insecure areas, and therefore could be "an important part of increased food security" in places like sub-Saharan Africa{{cite web|last=Halweil|first=Brian|title=Can Organic Farming Feed Us All?.|url=http://www.worldwatch.org/node/4060|publisher=World Watch Magazine|access-date=2 March 2014|archive-url=https://web.archive.org/web/20140209135230/http://www.worldwatch.org/node/4060|archive-date=9 February 2014|url-status=dead}}

FAO stressed that fertilizers and other chemical inputs can increase production, particularly in Africa where fertilizers are currently used 90% less than in Asia. For example, in Malawi the yield has been boosted using seeds and fertilizers.

Also NEPAD, a development organization of African governments, announced that feeding Africans and preventing malnutrition requires fertilizers and enhanced seeds.[https://web.archive.org/web/20100304023531/http://www.africafertilizersummit.org/ Meeting Africa's Food Challenge], The New Partnership for Africa's Development (NEPAD), 9–13 June 2006, Abuja, Nigeria.

The value of organic agriculture (OA) in the achievement of the Millennium Development Goals (MDG), particularly in poverty reduction efforts in the face of climate change, is shown by its contribution to both income and non-income aspects of the MDGs. These benefits are expected to continue in the post-MDG era. A series of case studies conducted in selected areas in Asian countries by the Asian Development Bank Institute (ADBI) and published as a book compilation by ADB in Manila document these contributions to both income and non-income aspects of the MDGs. These include poverty alleviation by way of higher incomes, improved farmers' health owing to less chemical exposure, integration of sustainable principles into rural development policies, improvement of access to safe water and sanitation, and expansion of global partnership for development as small farmers are integrated in value chains.{{Cite book|url=https://www.adb.org/publications/organic-agriculture-and-post-2015-development-goals|title=Organic Agriculture, Poverty Reduction, Climate Change, and the Millennium Development Goals (Chapter 1 of Organic Agriculture and Post-2015 Development Goals: Building on the Comparative Advantage of Poor Farmers)|date=June 23, 2015|publisher=Asian Development Bank|pages=3–48|first=Sununtar|last=Setboonsarng}}

A related ADBI study also sheds on the costs of OA programs and set them in the context of the costs of attaining the MDGs. The results show considerable variation across the case studies, suggesting that there is no clear structure to the costs of adopting OA. Costs depend on the efficiency of the OA adoption programs. The lowest cost programs were more than ten times less expensive than the highest cost ones. However, further analysis of the gains resulting from OA adoption reveals that the costs per person taken out of poverty was much lower than the estimates of the World Bank,World Bank. 2008.

Agriculture imposes negative externalities upon society through public land and other public resource use, biodiversity loss, erosion, pesticides, nutrient pollution, and assorted other problems. Positive externalities include self-reliance, entrepreneurship, respect for nature, and air quality.{{citation needed|date=May 2021}} Organic methods differ from conventional methods in the impacts of their respective externalities, dependent on implementation and crop type. Overall land use is generally higher for organic methods, but organic methods generally use less energy in production.{{Cite journal| last = Marshall | first = G. | year = 1991 | title= Organic Farming: Should Government Give it More Technical Support? | journal = Review of Marketing and Agricultural Economics | volume = 59 | issue = 3 | pages = 283–296 | url=http://ageconsearch.umn.edu/bitstream/12390/1/59030283.pdf}} The analysis and comparison of externalities is complicated by whether the comparison is done using a per unit area measurement or per unit of production, and whether analysis is done on isolated plots or on farm units as a whole.Stolze, M.; Piorr, A.; Häring, A.M. and Dabbert, S. (2000) Environmental impacts of organic farming in Europe. Organic Farming in Europe: Economics and Policy Vol. 6. Universität Hohenheim, Stuttgart-Hohenheim.

Measurements of biodiversity are highly variable between studies, farms, and organism groups. "Birds, predatory insects, soil organisms and plants responded positively to organic farming, while non-predatory insects and pests did not. A 2005 review found that the positive effects of organic farming on abundance were prominent at the plot and field scales, but not for farms in matched landscapes."{{Cite journal| last = Bengtsson | first = J. | year = 2005 | title= The effects of organic agriculture on biodiversity and abundance: a meta-analysis | journal = Journal of Applied Ecology | volume = 42 | issue = 2 | pages = 261–269 | doi = 10.1111/j.1365-2664.2005.01005.x | doi-access = free | bibcode = 2005JApEc..42..261B }}

Other studies that have attempted to examine and compare conventional and organic systems of farming and have found that organic techniques reduce levels of biodiversity less than conventional systems do, and use less energy and produce less waste when calculated per unit area, although not when calculated per unit of output. "Farm comparisons show that actual (nitrate) leaching rates per hectare[/acre] are up to 57% lower on organic than on conventional fields. However, the leaching rates per unit of output were similar or slightly higher." "On a per-hectare[/-acre] scale, the CO₂ emissions are 40{{Snd}}60% lower in organic farming systems than in conventional ones, whereas on a per-unit output scale, the CO₂ emissions tend to be higher in organic farming systems."{{cite journal|last=Hansen|first=Birgitt |author2=Alrøe, H.

According to a meta analysis published in 2017, compared to conventional agriculture, biological agriculture has a higher land requirement per yield unit, a higher eutrophication potential, a higher acidification potential and a lower energy requirement, but is associated with similarly high greenhouse gas emissions.

A 2003 to 2005 investigation by the Cranfield University for the Department for Environment, Food and Rural Affairs in the UK found that it is difficult to compare the global warming potential, acidification and eutrophication emissions but "Organic production often results in increased burdens, from factors such as nitrogen leaching and N₂O emissions", even though primary energy use was less for most organic products. N₂O is always the largest global warming potential contributor except in tomatoes. However, "organic tomatoes always incur more burdens (except pesticide use)". Some emissions were lower "per area", but organic farming always required 65 to 200% more field area than non-organic farming. The numbers were highest for bread wheat (200+ % more) and potatoes (160% more).[http://www.organicagcentre.ca/ResearchDatabase/res_enviro_burdens.asp Determining the environmental burdens and resource use in the production of agricultural and horticultural commodities] {{Webarchive|url=https://web.archive.org/web/20140329093718/http://www.organicagcentre.ca/ResearchDatabase/res_enviro_burdens.asp |date=29 March 2014 }}, Williams, A.G. et al., Cranfield University, U.K., August 2006.

Usually organic products required less energy, but more land. Per unit of product, organic produce generates higher nitrogen leaching, nitrous oxide emissions, ammonia emissions, eutrophication, and acidification potential than conventionally grown produce.[https://www.academia.edu/1907461/Does_organic_farming_reduce_environmental_impacts_-_A_meta-analysis_of_European_research Does organic farming reduce environmental impacts? - A meta-analysis of European research], H.L.

Smith et al. (2019) analysed the net greenhouse gas emissions resulting from a hypothetical full conversion of agriculture in England and Wales to 100% organic production. They estimated that such a transition would lead to a 40% reduction in food production compared to conventional farming. Domestic greenhouse gas emissionsemissions would decrease by 6%, but the lower yields would require increased food imports, resulting in land-use change abroad. In the medium scenario—where half of the additional land is converted from grassland and moderate soil carbon sequestration is assumed—this would lead to a 21% increase in global greenhouse gas emissions emissions compared to the conventional system.{{cite journal |last1=Smith |first1=Laurence G. |last2=Kirk |first2=Guy J.D. |last3=Jones |first3=Philip J. |last4=Williams |first4=Adrian G. |title=The greenhouse gas impacts of converting food production in England and Wales to organic methods |journal=Nature Communications |volume=10 |issue=1 |pages=4641 |year=2019 |doi=10.1038/s41467-019-12622-7 |url=https://www.nature.com/articles/s41467-019-12622-7 |pmc=6805889 }}

According to a 2012 meta-analysis of 71 studies, nitrogen leaching, nitrous oxide emissions, ammonia emissions, eutrophication potential and acidification potential were higher for organic products. Specifically, the emission per area of land is lower, but per amount of food produced is higher. This is due to the lower crop yield of organic farms. Excess nutrients in lakes, rivers, and groundwater can cause algal blooms, eutrophication, and subsequent dead zones. In addition, nitrates are harmful to aquatic organisms by themselves.{{Cite journal|title=Forecasting Agriculturally Driven Global Climate Change|journal=Science|date=21 March 2006|pmid=11303102|doi=10.1126/science.1057544|last1=Tilman|first1=D|last2=Fargione|first2=J|last3=Wolff|first3=B|last4=d'Antonio|first4=C|last5=Dobson|first5=A|last6=Howarth|first6=R|last7=Schindler|first7=D|last8=Schlesinger|first8=WH|last9=Simberloff|first9=D|volume=292|issue=5515|pages=281–4|bibcode=2001Sci...292..281T|last10=Swackhamer|first10=D|s2cid=23847498}}

A 2012 Oxford meta-analysis of 71 studies found that organic farming requires 84% more land for an equivalent amount of harvest, mainly due to lack of nutrients but sometimes due to weeds, diseases or pests, lower yielding animals and land required for fertility building crops. While organic farming does not necessarily save land for wildlife habitats and forestry in all cases, the most modern breakthroughs in organic are addressing these issues with success.{{cite web|title=Rodale Institute Farming Systems Trial|url=http://rodaleinstitute.org/our-work/farming-systems-trial/farming-systems-trial-30-year-report/|publisher=Rodale Institute|access-date=24 February 2014}}{{cite web|last=Undersander|first=Dan|title=Pastures for Profit: A Guide to Rotational Grazing|url=http://learningstore.uwex.edu/assets/pdfs/A3529.PDF|work=University of Wisconsin|publisher=Cooperative extension publishing|access-date=24 February 2014|display-authors=etal}}{{cite web|last=Undersander|first=Dan|title=Grassland Birds: Fostering Habitats Using Rotational Grazing|url=http://learningstore.uwex.edu/assets/pdfs/a3715.pdf|work=University of Wisconsin|publisher=Cooperative extension publishing|access-date=24 February 2014|display-authors=etal}}

The conservation of natural resources and biodiversity is a core principle of organic production.

Organic farming contributes to human capital by promoting biodiversity. The presence of various species in organic farms helps to reduce human input, such as fertilizers, and pesticides, which enhances sustainability.

The USDA's Agricultural Marketing Service (AMS) published a Federal Register notice on 15 January 2016, announcing the National Organic Program (NOP) final guidance on Natural Resources and Biodiversity Conservation for Certified Organic Operations. Given the broad scope of natural resources which includes soil, water, wetland, woodland and wildlife, the guidance provides examples of practices that support the underlying conservation principles and demonstrate compliance with USDA organic regulations § 205.200. The final guidance provides organic certifiers and farms with examples of production practices that support conservation principles and comply with the USDA organic regulations, which require operations to maintain or improve natural resources. The final guidance also clarifies the role of certified operations (to submit an OSP to a certifier), certifiers (ensure that the OSP describes or lists practices that explain the operator's monitoring plan and practices to support natural resources and biodiversity conservation), and inspectors (onsite inspection) in the implementation and verification of these production practices.{{Cite web|url=https://www.ams.usda.gov/sites/default/files/media/NOP%205020%20Biodiversity%20Guidance%20Rev01%20%28Final%29.pdf|title=USDSA Guidance Natural Resources and Biodiversity Conservation|date=15 January 2016|website=Agricultural Marketing Service, National Organic Program|publisher=United States Department of Agriculture|access-date=5 March 2016}}

}} There are four key issues when comparing the impacts on biodiversity of organic and conventional farming: (1) It remains unclear whether a holistic whole-farm approach (i.e. organic) provides greater benefits to biodiversity than carefully targeted prescriptions applied to relatively small areas of cropped and/or non-cropped habitats within conventional agriculture (i.e. agri-environment schemes); (2) Many comparative studies encounter methodological problems, limiting their ability to draw quantitative conclusions; (3) Our knowledge of the impacts of organic farming in pastoral and upland agriculture is limited; (4) There remains a pressing need for longitudinal, system-level studies in order to address these issues and to fill in the gaps in our knowledge of the impacts of organic farming, before a full appraisal of its potential role in biodiversity conservation in agroecosystems can be made.{{cite journal|last1=Hole|first1=D.G.|last2=Perkins|first2=A.J.|last3=Wilson|first3=J.D.|last4=Alexander|first4=I.H.|last5=Grice|first5=P.V.|last6=Evans|first6=A.D.|title=Does organic farming benefit biodiversity?|journal=Biological Conservation|date=March 2005|volume=122|issue=1|pages=113–130|doi=10.1016/j.biocon.2004.07.018|bibcode=2005BCons.122..113H }}

Organic agriculture is often considered to be more socially just and economically sustainable for farmworkers than conventional agriculture. However, there is little social science research or consensus as to whether or not organic agriculture provides better working conditions than conventional agriculture.{{Cite journal|last1=Shreck|first1=Aimee|last2=Getz|first2=Christy|last3=Feenstra|first3=Gail|date=2006-11-21|title=Social sustainability, farm labor, and organic agriculture: Findings from an exploratory analysis|journal=Agriculture and Human Values|volume=23|issue=4|pages=439–449|doi=10.1007/s10460-006-9016-2|s2cid=154663923|issn=0889-048X}} As many consumers equate organic and sustainable agriculture with small-scale, family-owned organizations it is widely interpreted that buying organic supports better conditions for farmworkers than buying with conventional producers.{{Cite journal|last1=Getz|first1=Christy|last2=Brown|first2=Sandy|last3=Shreck|first3=Aimee|date=December 2008|title=Class Politics and Agricultural Exceptionalism in California's Organic Agriculture Movement|journal=Politics & Society|volume=36|issue=4|pages=478–507|doi=10.1177/0032329208324709|s2cid=154411924|issn=0032-3292}} Organic agriculture is generally more labour-intensive due to its dependence on manual practices for fertilization and pest removal. Although illnesses from inputs pose less of a risk{{dubious|date=March 2022}}, hired workers still fall victim to debilitating musculoskeletal disorders associated with agricultural work. The USDA certification requirements outline growing practices and ecological standards but do nothing to codify labour practices. Independent certification initiatives such as the Agricultural Justice Project, Domestic Fair Trade Working Group, and the Food Alliance have attempted to implement farmworker interests but because these initiatives require voluntary participation of organic farms, their standards cannot be widely enforced.{{Cite journal|last1=Brown|first1=Sandy|last2=Getz|first2=Christy|date=May 2008|title=Privatizing farm worker justice: Regulating labor through voluntary certification and labeling|journal=Geoforum|volume=39|issue=3|pages=1184–1196|doi=10.1016/j.geoforum.2007.01.002|issn=0016-7185}} Despite the benefit to farmworkers of implementing labour standards, there is little support among the organic community for these social requirements. Many actors of the organic industry believe that enforcing labour standards would be unnecessary, unacceptable, or unviable due to the constraints of the market.

The EU-organic production-regulation is a part of the European Union regulation that sets rules about the production of organic agricultural and livestock products and how to label them. In the EU, organic farming and organic food are more commonly known as ecological or biological.

The regulation is derived from the guidelines of the International Federation of Organic Agriculture Movements (IFOAM), which is an association of about 800 member organizations in 119 countries.

As in the rest of the world, the organic market in Europe continues to grow and more land is farmed organically each year. "More farmers cultivate organically, more land is certified organic, and more countries report organic farming activities" as per the 2016 edition of the study "[http://www.fibl.org/en/media/media-archive/media-archive16/media-release15/article/bio-waechst-weiter-weltweit-437-millionen-hektar-bioflaeche.html The World of Organic Agriculture] {{Webarchive|url=https://web.archive.org/web/20171111203222/http://www.fibl.org/en/media/media-archive/media-archive16/media-release15/article/bio-waechst-weiter-weltweit-437-millionen-hektar-bioflaeche.html |date=11 November 2017 }}" according to data from the end of 2014 published by FiBL and IFOAM in 2016.

Denmark has a long ongoing support for converting conventional farming into organic farming, which has been taught in academic classes in universities since 1986. The state began substitutes and has promoted a special national label for products that qualify as organic since 1989. Denmark is thus the first country in the world to substitute organic farming, promoting the concept and organizing the distribution of organic products.{{Cite web|title=Økologiens historie|url=https://faktalink.dk/titelliste/okologi/okologiens-historie|access-date=2021-06-14|website=Faktalink}} Today the government accept applicants for financial support during conversion years, as in Danish regulations farms must not have utilized conventional farming methods such as the usage of pesticides for several years before products can be assessed for qualification as organic. This financial support has in recent years been cut due to organic farming increasing in profitability, and some goods surpassing the profitability of conventional farming in domestic markets. In general, the financial situation of organic farmers in Denmark boomed between 2010 and 2018, while in 2018 serious nationwide long-lasting droughts stagnated the economic results of organic farmers; however, the average farmer still achieved a net positive result that year.{{Cite web|title=Første gang i ti år: Økologer tjener færre penge|url=https://landbrugsavisen.dk/f%C3%B8rste-gang-i-ti-%C3%A5r-%C3%B8kologer-tjener-f%C3%A6rre-penge|access-date=2021-06-14|website=LandbrugsAvisen|language=da}} In 2021 Denmark's (and Europe's) largest slaughterhouse, Danish Crown, publicized its expectations of stagnating sales of conventional pork domestically, however it expected increasing sales of organic pork and especially free range organic pork.{{Cite web|title=Danish Crown-datter vil slagte langt flere grise|url=https://landbrugsavisen.dk/danish-crown-datter-vil-slagte-langt-flere-grise|access-date=2021-06-14|website=LandbrugsAvisen|language=da}} Besides the conversion support, there are still base subsidies for organic farming paid per area of qualified farm land.{{Cite web|title=Økologisk Arealtilskud|url=https://lbst.dk/tilskudsguide/oekologisk-arealtilskud-5-aarige-tilsagn/#c4457|access-date=14 June 2021|website=Landbrugsstyrelsen}}

The first Danish private development organisation, SamsØkologisk, was established in 2013, by veteran organic farmers from the existing organisation Økologisk Samsø. The development organisation has intentions to buy and invest in farmland and then lend the land to young and aspiring farmers seeking to get into farming, especially organic farming. This organisation reports 300 economical active members as of 2021, but does not publish the amount of acquired land or active lenders.{{Cite web|title=Om os {{!}} Økologisk Samsø|url=https://oekologisksamsoe.dk/om-os/|access-date=2021-06-14|language=da-DK}}

However, the organic farming concept in Denmark is often not limited to organic farming as the definition is globally. Instead, the majority of organic farming is instead "ecological farming". The development of this concept has been parallel with the general organic farming movement, and is most often used interchangeable with organic farming. Thus, there is a much stronger focus on the environmental and especially the ecological impact of ecological farming than organic farming. E.g. besides the base substitute for organic farming, farmers can qualify for an extra substitute equal to 2/3 of the base for realizing a specific reduction in the usage of added nitrogen to the farmland (also by organic means). There are also parallels to the extended organic movements of regenerative agriculture, although far from all concepts in regenerative agriculture are included in the national strategy at this time, but exist as voluntary options for each farmer. For these reasons, international organic products do not fulfill the requirements of ecological farming and thus do not receive the domestic label for ecological products, rather they receive the standard European Union organic label.

• Organic Farming has grown by {{convert|3.53|e6acres|abbr=off}} in the U.S. from 2000 to 2011.{{Cite journal |last1=Squalli |first1=Jay |last2=Adamkiewicz |first2=Gary |date=2018-08-10 |title=Organic farming and greenhouse gas emissions: A longitudinal U.S. state-level study |journal=Journal of Cleaner Production |volume=192 |pages=30–42 |doi=10.1016/j.jclepro.2018.04.160 |bibcode=2018JCPro.192...30S |s2cid=158696303 |issn=0959-6526}}
• In 2016, California had 2,713 organic farms, which makes California the largest producer of organic goods in the U.S.
• 4% of food sales in the U.S. are of organic goods.{{Cite web|title=USDA ERS - Organic Agriculture |url=https://www.ers.usda.gov/topics/natural-resources-environment/organic-agriculture/|access-date=2020-11-18 |website=www.ers.usda.gov}}

As was the case with most countries, Sri Lanka made the transition away from organic farming upon the arrival of the Green Revolution, whereupon it started depending more on chemical fertilizers. This became a highly popularized method when the nation started offering subsidies on the import of artificial fertilizers to increase rice paddy production, and to incentivize farmers to switch from growing traditional varieties into using high yielding varieties (HYVs).{{cite web |last1=Weerahewa |first1=Jeevika |last2=Kodithuwakku |first2=Sarath S. |last3=Ariyawardana |first3=Anoma |date=2010 |title=The Fertilizer Subsidy Program in Sri Lanka |url=https://ecommons.cornell.edu/handle/1813/55709 |language=en-US}} This was especially true for young farmers who saw short-term economic profit as more sustainable to their wellbeing, compared to the long term drawbacks to the environment.{{cite journal |last=SOORIYAKUMAR |first=K |title=Farmers' Willingness to Pay for the Ecosystem Services of Organic Farming: A Locality Study in Valikamam Area of Sri Lanka |date=2019 |journal=Applied Ecology and Environmental Research |volume=17 |issue=6 |page=13815 |doi=10.15666/aeer/1706_1380313815 |doi-access=free |bibcode=2019ApEER..1713815S |s2cid=216122392 |issn=1589-1623}} However, due to the various health concerns with inorganic farming including the possibility of a chronic kidney disease being associated with chemical fertilizers, many middle aged and experienced farmers displayed skepticism towards these new approaches. Some even resorted to organic farming or utilizing insecticide free fertilizers for their crops.{{Cite journal |last1=Horgan |first1=Finbarr G. |last2=Kudavidanage |first2=Enoka P. |date=2020-06-01 |title=Use and Avoidance of Pesticides as Responses by Farmers to change Impacts in Rice Ecosystems of Southern Sri Lanka |journal=Environmental Management |language=en |volume=65 |issue=6 |pages=787–803 |doi=10.1007/s00267-020-01272-x |pmid=32107569 |bibcode=2020EnMan..65..787H |s2cid=211525758 |issn=1432-1009}} In a study conducted by F. Horgan and E. Kudavidanage, the researchers compared crop yields of farmers in Sri Lanka who employed distinct farming techniques including organic farmers who grew traditional varieties, and insecticide-free fertilizer users and pesticide users who grew modern varieties. No significant difference was found among the yield productions and in fact, organic farmers and insecticide-free fertilizer users lamented less about insects such as planthoppers as a challenge to their production. Regardless, many farmers continued to use insecticides to avoid the predicted dangers of pests to their crops, and the cheap sale of agrochemicals provided an easy approach to augment crop growth. Additionally, while organic farming has health benefits, it's a strenuous task which requires more man power.{{Cite journal |last1=Qiao |first1=Yuhui |last2=Halberg |first2=Niels |last3=Vaheesan |first3=Saminathan |last4=Scott |first4=Steffanie |date=2015-06-08 |title=Assessing the social and economic benefits of organic and fair trade tea production for small-scale farmers in Asia: a comparative case study of China and Sri Lanka |journal=Renewable Agriculture and Food Systems |language=en |volume=31 |issue=3 |pages=246–257 |doi=10.1017/S1742170515000162 |s2cid=154966563 |issn=1742-1705}} Although that presented a great opportunity for increased employment in Sri Lanka, the economic compensation was not enough to suffice the living expenses of those employed. Thus, most farmers relied on modern methods to run their household, especially after the economic stressors brought on by COVID-19.{{Cite web |author1=Ted Nordhaus |author2=Saloni Shah |date=March 5, 2022 |title=In Sri Lanka, Organic Farming Went Catastrophically Wrong |url=https://foreignpolicy.com/2022/03/05/sri-lanka-organic-farming-crisis/ |access-date=2022-07-12 |website=Foreign Policy}}

However, while Sri Lanka was still facing the new challenges of the pandemic, in the 2019 presidential election campaign, the president, Gotabaya Rajapaksa proposed a 10-year, national transition to organic farming to declare Sri Lanka as the first nation to be known for its organic produce.{{Cite news |title=A rush to farm organically has plunged Sri Lanka's economy into crisis |newspaper=The Economist |url=https://www.economist.com/asia/2021/10/16/a-rush-to-farm-organically-has-plunged-sri-lankas-economy-into-crisis |access-date=2022-07-12 |issn=0013-0613}} On April 27, 2021,{{Cite news |date=2022-06-14 |title=Sri Lanka's organic revolution hits farmers hard |language=en |work=Le Monde.fr |url=https://www.lemonde.fr/en/environment/article/2022/06/14/in-sri-lanka-the-sabotage-of-an-organic-revolution_5986670_114.html |access-date=2022-08-22}} the country issued an order prohibiting the import of any inorganic pesticides or fertilizers, creating chaos among farmers.{{Cite web |last=Mendis |first=Bakthi Dharmapriya |title=Prof. Vandana Shiva hails Lanka's decision to ban chemical fertilizer |url=https://www.dailynews.lk/2021/06/09/local/251203/prof-vandana-shiva-hails-lanka%E2%80%99s-decision-ban-chemical-fertilizer |access-date=2021-10-05 |website=Daily News |language=en}}{{Cite web |date=2021-06-08 |title=Sri Lanka Going Organic: Rethink the strategy; Agriculturists Write to President |website=The Sri Lankan Scientist |url=https://scientist.lk/2021/06/08/sri-lanka-going-organic-rethink-the-strategy-agriculturists-write-to-president/ |access-date=2022-07-12}}{{Cite journal |last=Priyadarshana |first=Tharaka S. |date=2021-12-03 |title=Sri Lanka's hasty agrochemical ban |url=https://www.science.org/doi/10.1126/science.abm9186 |journal=Science |language=en |volume=374 |issue=6572 |pages=1209 |doi=10.1126/science.abm9186 |pmid=34855499 |bibcode=2021Sci...374.1209P |s2cid=244856651 |issn=0036-8075}} While such a change was made over concerns for the nation's ecosystems and the health of citizens where pesticide poisonings prevailed over other health related deaths,{{Cite journal |last1=Van Der Hoek |first1=W. |last2=Konradsen |first2=F. |last3=Athukorala |first3=K. |last4=Wanigadewa |first4=T. |date=1998-02-01 |title=Pesticide poisoning: A major health problem in Sri Lanka |journal=Social Science & Medicine |language=en |volume=46 |issue=4 |pages=495–504 |doi=10.1016/S0277-9536(97)00193-7 |pmid=9460829 |issn=0277-9536}} the precipitous decision was met with criticism from the agriculture industry. This included fears that the mandate would harm the yields of the country's major crops (despite claims to the contrary), that the country would not be able to produce enough organic fertilizer domestically, and organic farming being more expensive and complex than conventional agriculture.{{Cite web |title=Organic food revolution in Sri Lanka threatens its tea industry |url=https://www.aljazeera.com/news/2021/9/1/organic-food-revolution-sri-lanka-tea-industry |access-date=2022-07-12 |website=Al Jazeera |language=en}} To put this into perspective, 7.4% of Sri Lanka's GDP is reliant on agriculture and 30% of citizens work in this sector.{{Cite web |date=2021-09-28 |title=Sri Lanka Commercial Guide |url=https://www.trade.gov/country-commercial-guides/sri-lanka-agricultural-sector |website=International Trade Administration}} This means that about ⅓ of its population is dependent on this sector for jobs, making its maintenance highly crucial for the prosperity of the nation's social and economic status. Of special concern was rice and tea, which are a staple food and major export respectively.

Despite it being a record crop in the first half of 2021, the tea crop began to decline in July of that year. Rice production fell by 20% over the first six months of the ban, and prices increased by around 50%. Contrary to its past success at self-sustainability, the country had to import US$450 million worth of rice to meet domestic demand. In late August, the government acknowledged the ban had created a critical dependency on supplies of imported organic fertilizers, but by then food prices had already increased twofold in some cases.{{Cite web |last1=P |first1=Samyak |last2=ey |date=2021-09-05 |title=How Sri Lanka's overnight flip to total organic farming has led to an economic disaster |url=https://theprint.in/world/how-sri-lankas-overnight-flip-to-total-organic-farming-has-led-to-an-economic-disaster/728414/ |access-date=2021-09-08 |website=ThePrint |language=en-US}} In September 2021, the government declared an economic emergency, citing the ban's impact on food prices, as well as inflation from the devaluation of Sri Lankan currency due to the crashing tea industry, and a lack of tourism induced by COVID-19 restrictions.{{Cite news |last=Perumal |first=Prashanth |date=2021-09-06 |title=Explained {{!}} What caused the Sri Lankan economic crisis? |language=en-IN |work=The Hindu |url=https://www.thehindu.com/business/explained-what-caused-the-sri-lankan-economic-crisis/article36314148.ece |access-date=2021-09-07 |issn=0971-751X}}{{Cite news |date=2021-09-01 |title=Covid: Sri Lanka in economic emergency as food prices soar |language=en-GB |work=BBC News |url=https://www.bbc.com/news/business-58390292 |access-date=2021-09-05}}

In November 2021, the country partially lifted the ban on inorganic farming for certain key crops such as rubber and tea, and began to offer compensation and subsidies to farmers and rice producers in an attempt to cover losses.{{cite web |last1=Wipulasena |first1=Aanya |last2=Mashal |first2=Mujib |date=7 December 2021 |title=Sri Lanka's Plunge Into Organic Farming Brings Disaster |url=https://www.nytimes.com/2021/12/07/world/asia/sri-lanka-organic-farming-fertilizer.html |access-date=19 January 2022 |website=The New York Times}}{{Cite news |last=Watt |first=Louise |date=2021-11-21 |title=Sri Lanka abandons drive to become world's first organic country amid spiralling food prices |language=en-GB |work=The Daily Telegraph |url=https://www.telegraph.co.uk/world-news/2021/11/21/sri-lanka-abandons-drive-become-worlds-first-organic-country/ |access-date=2022-01-18 |issn=0307-1235}} The previous subsidies on synthetic fertilizer imports were not reintroduced.
