Crop rotation
Crop rotation is the practice of growing a series of dissimilar/different types of crops in the same area in sequenced seasons.It also helps in reducing soil erosion and increases soil fertility and crop yield. Crop rotation gives various nutrients to the soil. A traditional element of crop rotation is the replenishment of nitrogen through the use of green manure in sequence with cereals and other crops. 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.
