Which of the following is a positive effect of using cover crops?

Using cover crops plays a vital role in agricultural systems, particularly in enhancing soil health and preventing erosion. When cover crops are planted, their roots help to hold the soil in place, which reduces the risk of erosion caused by wind and water. This is especially important on sloped terrains where soil can easily be washed away during rainfall or blown away during high winds.

Cover crops also contribute to improving soil structure and increasing organic matter as they decompose, further enhancing the soil's ability to retain moisture and nutrients. This protective layer on the surface of the soil can significantly diminish surface runoff and soil degradation, promoting long-term sustainability in farming practices. By effectively stabilizing the soil, cover crops create a more resilient agricultural ecosystem that can better withstand various environmental stresses.
