Crop rotation is the practice of growing a series of dissimilar types of crops in the same area in sequential seasons.

Crop rotation confers various benefits to the soil.

Crop rotation also mitigates the build-up of pathogens and pests that often occurs when one species is continuously cropped, and can also improve soil structure and fertility by alternating deep-rooted and shallow-rooted plants.

Crop rotation is one component of polyculture.

Crop rotation is also used to control pests and diseases that can become established in the soil over time.

Crop rotation can greatly affect the amount of soil lost from erosion by water.

* Crop rotation can break the disease cycle because many rusts are host specific.

Crop rotation and green manure (" cover crops ") help to provide nitrogen through legumes ( more precisely, the Fabaceae family ) which fix nitrogen from the atmosphere through symbiosis with rhizobial bacteria.

Crop rotation or crop sequencing is the practice of growing a series of dissimilar types of crops in the same space in sequential seasons for various benefits such as to avoid the build up of pathogens and pests that often occurs when one species is continuously cropped.

Crop rotation also seeks to balance the fertility demands of various crops to avoid excessive depletion of soil nutrients.

Crop rotation can also improve soil structure and fertility by alternating deep-rooted and shallow-rooted plants.

Crop rotation should also be employed to avoid infected soil / seed beds for at least two years.

Crop rotation can also help build up a soils infrastructure.
