What is the primary benefit of using cover crops in agriculture?

• A. To increase crop yield
• B. To improve soil health
• C. To reduce pests
• D. To enhance irrigation efficiency

Answer: (B)

The primary benefit of using cover crops in agriculture is to improve soil health. Cover crops contribute to soil health in several important ways. They help prevent soil erosion by protecting the soil surface with vegetation, which stabilizes the soil structure. Additionally, these crops can enhance soil fertility through the addition of organic matter when they decompose, and some cover crops, particularly legumes, can fix nitrogen from the atmosphere, enriching the soil with this essential nutrient. Improved soil health from cover crops also leads to better water retention and reduced compaction, which can create more favorable conditions for subsequent crops. Healthy soils are critical for sustaining agricultural productivity over time, making this benefit significant. While cover crops can also lead to increased crop yields, pest reduction, and improved irrigation efficiency, these are secondary effects that often arise as a result of the foundational improvement in soil health. Healthy soil typically supports stronger root systems, better nutrient availability, and overall more resilient plants. Thus, enhancing soil health stands out as the primary, overarching benefit of utilizing cover crops in agricultural practices.
