Crop rotation is an agricultural practice where different types of crops are planted in the same area across different seasons or years. This method helps maintain soil fertility, reduce soil erosion, and prevent the buildup of pests and diseases that can occur when the same crop is grown repeatedly. By alternating crops, farmers can improve the overall health of their soil and increase yields. For example, a farmer might plant corn one year, followed by soybeans the next. Soybeans are legumes that can fix nitrogen in the soil, enriching it for the next crop. This sustainable practice not only benefits the environment but also enhances farm productivity.
