What is one method to prevent wind erosion?

Planting grass is an effective method for preventing wind erosion because it helps stabilize the soil. The roots of grass plants bind the soil together, reducing its susceptibility to being blown away by strong winds. Additionally, grass can serve as a protective cover that slows down wind velocity at the soil surface, further minimizing the potential for erosion.

In contrast, the other options do not address wind erosion effectively. Using heavy machinery can disturb the soil structure, making it more prone to erosion. Applying pesticides primarily targets pests and diseases rather than addressing soil stability. Harvesting crops does not inherently prevent erosion; in fact, leaving soil bare after harvesting can increase the risk of wind erosion during open periods. Therefore, planting grass stands out as the most suitable choice for erosion control.
