The “Crop Rotation Practice Standard” for the National Organic Program under the U.S. Code of Federal Regulations, section §205.205, states that Farmers are required to implement a crop rotation that maintains or builds soil organic matter, works to control pests, manages and conserves nutrients, and protects against erosion.
A set of crops is rotated from one field to another. The technique was first used in China in the Eastern Zhou period, [1] and was adopted in Europe in the medieval period. Three-field system with ridge and furrow fields (furlongs) The three-field system lets farmers plant more crops and therefore increase production.
The Old Rotation experiment, which started in 1896, is the third-oldest ongoing field crop experiment in the United States and the oldest continuous cotton experiment in the world. It was the first experiment to show that a cotton/ legume crop rotation would allow soil to support a cotton crop indefinitely.
[149] [150] At the same time, some farmers in Europe moved from a two field crop rotation to a three-field crop rotation in which one field of three was left fallow every year. This resulted in increased productivity and nutrition, as the change in rotations permitted nitrogen-fixing legumes such as peas, lentils and beans. [ 151 ]
Later they employed a three-year, three field crop rotation routine, with a different crop in each of two fields, e.g. oats, rye, wheat, and barley with the second field growing a legume like peas or beans, and the third field fallow. Normally from 10% to 30% of the arable land in a three crop rotation system is fallow. Each field was rotated ...
Crop rotation is a tried-and-true practice that has been used not just in home vegetable gardens but in full-scale farming operations since the 17th century. It consists of moving a family of ...
The crops introduced by the Arabs included sugar cane, rice, hard wheat (durum), citrus, cotton, and figs. Many of these crops required sophisticated methods of irrigation, water management, and "agricultural technologies such as crop rotation, management of pests, and fertilizing crops by natural means."
Leading up to 2024, experts predicted the proliferation of Caesar salads, ranch dressing, and rooster-shaped pasta — and it all came to fruition, to varying degrees, over the last year in ...
