Which practice helps in reducing soil erosion?

• A. Deep tillage
• B. Cover cropping
• C. Frequent irrigation
• D. Fertilization

Answer: (B)

Cover cropping plays a significant role in reducing soil erosion by providing ground cover that protects the soil from wind and water erosion. When crops are planted specifically to cover the soil, they help to bind the soil together with their root systems, which stabilizes it and reduces the chances of soil particles being washed or blown away. Additionally, cover crops improve soil structure and enhance moisture retention, which further contributes to minimizing erosion risk. In contrast, deep tillage can disturb the soil structure, potentially increasing the risk of erosion by leaving the soil exposed. Frequent irrigation, while important for crop health, does not provide any protective cover for the soil and may even exacerbate erosion, especially on slopes. Fertilization focuses on nutrient supply and does not address soil erosion directly, leaving the soil vulnerable during heavy rains or high winds. Thus, cover cropping is a proactive measure that directly targets soil erosion prevention.
