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.
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 ...
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.
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.
Polyculture is the growing of multiple crops together in the same place at the same time. It has traditionally been the most prevalent form of agriculture. [1] Regions where polycultures form a substantial part of agriculture include the Himalayas, Eastern Asia, South America, and Africa. [2]
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]
By affecting the soil in different ways, crops in a rotation help to stabilise changes in the properties. Another consideration is that many agricultural pests are species-specific and so having a given species present in a field only some of the time helps to prevent populations of pests from growing. [6] The organisation of individual plants ...
Intercropping is a multiple cropping practice that involves the cultivation of two or more crops simultaneously on the same field, a form of polyculture. [1] [2] The most common goal of intercropping is to produce a greater yield on a given piece of land by making use of resources or ecological processes that would otherwise not be utilized by a single crop.
