In the agricultural practices cover plants are grown for the enrichment and the protection of the soil. They are not harvested to be sold as cash crops.
<h3>What are the cover crops used for?</h3>
Cover crops are grown in the agricultural land parts to maintain the soil fertility and quality so that the land will be safe from the invasion and attacks of pests and weeds.
They are generally grown after the reaping of cash crops and help in soil binding by preventing erosion from the water runoffs.
