How can crop rotation improve?

Pest control is the main benefit of crop rotation. If a farmer plants one type of crop and swaps it out when it starts to attract a certain type of bug it will be awhile before more are attracted to the new plant

Crop rotation can also be used to replenish nutrients in the soil. For example, a crop that takes a lot of nitrogen can be planted one year, and the next year one that replenishes nitrogen can be planted.
