Cover crops are plants that are planted to cover the soil to keep it in place and improve soil health. They can be intercropped with other crops or planted after harvesting. The crops are mainly grown to protect the soil from soil erosion and enhance the quality of the soil. Cover crops can help a farmer minimize costs incurred during soil protection activities and produce pasture that can be used as animal feeds.
Cover crops can be grown between regular crops like corn, soya bean, and wheat. Examples of cover crops are annual ryegrass, crimson clover, oats, oil-seed radishes, and cereal rye.
