What is Diversified crop rotation?

Diversified crop rotation is required for providing food for the soil microorganisms along with nutrients utilization by the crops in rotation which are present in different soil layers due to leaching. It can be attained by rotating deep rooted crops with shallow rooted crops. The crop rotations which mainly involve legumes are beneficial for biological nitrogen fixation, reducing pest infestation by disruption of the pest’s life cycle and also improving biodiversity.
