Cover crops are plants grown primarily to improve soil health rather than for harvest. They are typically planted during the off-season when main crops are not being cultivated. These crops help prevent soil erosion, enhance soil structure, and increase organic matter, which can lead to better water retention and nutrient availability. Common types of cover crops include clover, rye, and vetch. Farmers often use them to suppress weeds, reduce pests, and break disease cycles. By incorporating cover crops into their farming practices, growers can promote sustainable agriculture and improve the overall productivity of their land.
