Crop rotation

Crop rotation is a way farmers use to keep their soil healthy. Farmers grow different types of crops in their fields each year. So, one year they may grow wheat in their field, and then the next year they may grow corn. This helps the soil to stay healthy because different crops need different nutrients. The different crops also help keep pests away. So, the crops help keep the soil healthy and the pests away so the farmer can grow healthy crops each year.
