Abstract: Cover crops are a critical component in sustainable agriculture, significantly contributing to soil fertility and health. This review explores the various mechanisms by which cover crops enhance soil quality, including their impact on soil structure, organic matter content, and nutrient cycling. Cover crops improve soil structure by reducing erosion, increasing aggregate stability, and enhancing water infiltration. They also boost soil organic matter through the decomposition of plant residues, which contributes to the formation of humus and supports microbial activity. Furthermore, certain cover crops can fix atmospheric nitrogen, thereby replenishing soil nutrient levels and reducing the need for synthetic fertilizers. By integrating cover crops into crop rotations, farmers can achieve long-term improvements in soil fertility, leading to increased agricultural productivity and environmental sustainability. This synthesis of current research highlights the importance of cover crops in promoting soil health and provides practical insights for their effective implementation in agricultural systems.
