Which of the following is a benefit of cover crops?

Cover crops play a crucial role in sustainable agriculture, and one of their primary benefits is their ability to reduce soil erosion and improve soil structure. By providing ground cover, these crops protect the soil from wind and water erosion, which can strip away nutrient-rich topsoil. The roots of cover crops also help bind the soil particles together, improving soil structure and promoting water infiltration.

Additionally, as cover crops decompose, they add organic matter back into the soil, enhancing its fertility and health. This leads to better water retention and nutrient availability for subsequent crops. Overall, the practice of using cover crops is an effective strategy for maintaining soil integrity, enhancing agricultural productivity, and promoting environmental sustainability.

While other options mention benefits such as water efficiency or high yields, these factors can vary significantly between cover crops and conventional crops and are not the primary reasons for using cover crops in sustainable agricultural practices.
