Which agricultural-related benefit is associated with using cover crops?

Using cover crops provides a variety of agricultural benefits, one of which includes reduced soil compaction. When cover crops are grown, their root systems penetrate the soil, creating channels that improve soil structure and porosity. This enhanced structure allows for better water infiltration, reduces surface runoff, and alleviates compaction that may result from heavy machinery or prolonged farming activities. Improved soil aeration also leads to healthier root development for subsequent crops, thereby promoting overall soil health.

The other choices presented do not align with the benefits of cover crops. Increased irrigation needs would imply that moisture retention in the soil is compromised, which is contrary to the purpose of cover crops. Higher pest populations generally indicate a negative impact, whereas cover crops can often help suppress pests and diseases. Lastly, decreased soil moisture is not a benefit associated with cover crops; rather, they typically help to conserve soil moisture through enhanced organic matter and root structure, ultimately leading to better moisture retention.
