Which practice helps reduce soil erosion by wind?

• A. Using synthetic fertilizers
• B. Growing vegetation
• C. Implementing clear-cut logging
• D. Weekly tilling of the land

Answer: (B)

Growing vegetation is an effective practice for reducing soil erosion by wind because it provides a protective cover over the soil surface. Plants, including grasses and shrubs, help stabilize the soil with their root systems, which bind the soil particles together. Additionally, the leaves and stems of the plants act as physical barriers to wind, reducing its speed at the surface and preventing the soil from being blown away. The presence of vegetation also enhances moisture retention in the soil, further contributing to soil stability. When vegetation is healthy and well-established, it can significantly reduce the impact of wind erosion, helping to maintain soil quality and prevent degradation. Other practices, such as using synthetic fertilizers or tilling the land, do not directly contribute to reducing wind erosion. In fact, excessive tilling can exacerbate erosion issues by exposing bare soil to wind. Clear-cut logging, on the other hand, removes vegetation entirely, making the soil more susceptible to erosion by both wind and water.
