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 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 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]
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 ...
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] Although the specific mechanisms regulating that effect are not fully understood, [ 4 ] they are thought to be related to differential effects on ...
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 ...
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.
Agricultural monocultures refer to the practice of planting one crop species in a field. [15] Monoculture is widely used in intensive farming and in organic farming.In crop monocultures, each plant in a field has the same standardized planting, maintenance, and harvesting requirements resulting in greater yields and lower costs.
