Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons. This practice reduces the ...
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 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 ...
Crop rotation plays an important role in replenishing soil nutrients, especially atmospheric nitrogen converted to usable forms by nitrogen-fixing bacteria that form a relationship with legumes such as soybeans. Some legumes can also be used as cover crops or planted in fallow fields.
The third principle is the practicing diverse crop rotations or crop interactions. According to an article published in the Physiological Transactions of the Royal Society called "The role of conservation agriculture and sustainable agriculture", crop rotation can be used best as a disease control against other preferred crops (Hobbs et al ...
Using crop rotation and cover crops to suppress nematodes in potatoes [58] Integrated multi-trophic aquaculture is a practice in which the by-products (wastes) from one species are recycled to become inputs (fertilizers, food) for another.
