Which of the following is a benefit of planting cover crops?

Decreases organic matter in soil

Improves soil structure

Planting cover crops offers numerous benefits, one of which is the improvement of soil structure. Cover crops, such as legumes and grasses, help to create a network of roots in the soil. These roots enhance soil aggregation and porosity, which allows for better air and water movement within the soil. Improved soil structure promotes a healthy habitat for soil organisms and can lead to increased productivity in the following growing season.

Additionally, cover crops can reduce soil erosion by protecting the soil surface, enhancing its stability and structure. The organic matter contributed by decaying cover crops further enriches the soil, leading to better overall soil health. This holistic improvement in soil quality contributes to better crop yields, sustainable farming practices, and increased resilience against extreme weather events.
