Which agricultural practice is directly aimed at preventing soil erosion?

• A. Monoculture
• B. Cover cropping
• C. Pesticide application
• D. Using synthetic fertilizers

Answer: (B)

Cover cropping is an agricultural practice specifically designed to prevent soil erosion. When cover crops are planted, they create a protective layer of vegetation that helps hold soil in place, reducing the impact of rainfall and wind. The roots of the plants improve soil structure, enhance moisture retention, and increase organic matter, further stabilizing the soil. This practice not only minimizes soil loss but also promotes overall soil health by improving nutrient cycling and supporting beneficial microbial activity.

In contrast, monoculture can increase erosion risk as it often results in bare soil when crops are not growing. Pesticide application and the use of synthetic fertilizers focus on pest control and nutrient supply, respectively, without direct impact on the physical stability of the soil. These practices may inadvertently lead to erosion if they do not include measures to protect the soil's surface. Therefore, cover cropping stands out as the most effective method explicitly aimed at preventing soil erosion.
