What is a way to prevent wind erosion?

Maintaining soil cover is an effective way to prevent wind erosion because it protects the soil surface from the direct impact of wind. Soil cover can take various forms, such as vegetation, crop residues, or cover crops. These elements create a barrier against wind forces, which can otherwise displace fine soil particles. With adequate cover, the soil is better anchored, reducing the likelihood of erosion. When the soil is covered, it also improves moisture retention and enhances organic matter, further contributing to soil health and structure.

The other options do not contribute effectively to minimizing wind erosion. Keeping the soil surface bare leaves the topsoil exposed and vulnerable to wind, while increasing tilling depth can disturb soil structure and make it more prone to erosion. Using crops that require high water does not address wind erosion directly and does not provide the necessary soil cover to shield against wind impact.
