Crop rotation is the practice of changing the types of crops you plant in a specific area from season to season. Instead of planting the same crop in the same spot year after year, you rotate different crops across your fields. This method is not only effective at improving soil fertility but also at breaking pest cycles, reducing weed pressure, and preventing soil erosion. By alternating crops, you can maintain a balance of nutrients in the soil. For example, leguminous plants such as beans and peas can fix nitrogen in the soil. This benefits other crops like corn and wheat, which are heavy nitrogen users.
