The primary role of cover crops in sustainable farming is improving soil health and reducing erosion.

Cover crops are crucial to sustainable farming because of their capacity to enhance soil health and reduce erosion. Clovers, legumes, and grasses are among the plants that are sown in the off-season or in between cash crops to conserve and enhance the soil. Cover crops help minimize erosion by improving soil structure and reducing the impact of rainfall on exposed soil. By increasing organic matter, fixing minerals, and cultivating beneficial bacteria, they also increase soil fertility. Cover crops promote long-term agricultural sustainability, increase yields, and reduce the demand for synthetic fertilizers and pesticides.
