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.
The Norfolk four-course system is a method of agriculture that involves crop rotation. Unlike earlier methods such as the three-field system, the Norfolk system is marked by an absence of a fallow year. Instead, four different crops are grown in each year of a four-year cycle: wheat, turnips, barley, and clover or ryegrass. [1]
The three-field system is a regime of crop rotation in which a field is planted with one set of crops one year, a different set in the second year, and left fallow in the third year. A set of crops is rotated from one field to another.
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.
Many modern farms are made up of a number of fields, which can be cultivated separately and thus can be used in a crop rotation sequence. Crop rotation has been employed for thousands of years and has been widely found to increase yield and prevent harmful changes to the soil environment that limit productivity in the long term. [3]
In agriculture, monocropping is the practice of growing a single crop year after year on the same land. Maize, soybeans, and wheat are three common crops often monocropped. Monocropping is also referred to as continuous cropping, as in "continuous corn." Monocropping allows for farmers to have consistent crops throughout their entire farm.
The open-field system used a three-field crop rotation system. Barley , oats , or legumes would be planted in one field in spring, wheat or rye in the second field in the autumn. [ 31 ] There was no such thing as artificial fertilizer in mediaeval England, so the continual use of arable land for crops would exhaust the fertility of the soil.
A whole new "system of crop rotation, fertilization, transplanting, grafting, and irrigation" was swiftly and systematically put into place under a new legal framework of land ownership and tenancy. In her view, therefore, there was indeed an agricultural revolution in al-Andalus, but it consisted principally of new social institutions rather ...
