One way that farms can control runoff is by planting cover crops when the fields do not have anything planted in them. A cover crop is a crop that is planted mostly during the winter when most other plants cannot grow. Farmers plant these crops to help stop soil erosion. Cover crops help stop erosion because these plants hold the soil in place with their roots, which means that wind or water cannot wash the soil away. Cover crops also help to increase the organic matter in soil, which increases soil health.
