Roots help prevent erosion of soil by wind and water. Soil is held in place by the dense network of roots of grasses, trees, and other plants. Plants called legumes, which include clover, peas, and soybeans, help enrich the soil. Swellings on their roots contain bacteria that convert nitrogen from the air into compounds. These compounds are useful to the plant. After the plant dies, the compounds become part of the soil.
