== Agriculture ==

  • European writings make the first known mention of a three-field system in use in medieval Europe. The crop rotation is the practice of growing a series of different types of crops in the same area in sequential seasons. Under this system, the land of an estate or village is divided into three large fields, and makes a given section of land productive 2 years out of 3, instead of every other year (approximate date).
