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 the soil. For example, planting legumes like beans or peas can add nitrogen back into the soil, benefiting subsequent crops. This sustainable approach not only enhances crop yields but also promotes biodiversity in farming systems.
