Answer

  1. Increase in soil fertility

Explanation:

Crop rotation is the process of growing a series of different crops in the same area in sequenced seasons. Crop rotation helps in increasing soil fertility. For example, growing legumes as fodder in one season and wheat in the next season can help in the replenishment of the soil with nitrogen. It also helps in reducing soil erosion and increasing crop yield.
