Which of the following is crucial for controlling soil erosion?

Implementing proper land management practices is essential for controlling soil erosion because it encompasses a range of strategies that maintain soil health and structure, reduce runoff, and protect the soil from the forces of erosion. Effective land management can include practices such as crop rotation, contour farming, terracing, and maintaining ground cover—all of which help enhance soil stability and minimize erosive forces.

By carefully managing land, farmers and landowners can improve the soil's ability to retain moisture, reduce the speed of water runoff, and encourage the growth of root systems that bind the soil particles together. This holistic approach not only protects against erosion but also promotes sustainable agricultural practices and improves overall ecosystem health.

In contrast, options involving increased chemical fertilizers or pesticide application may inadvertently harm soil structure or microbial life, leading to higher erosion rates. Additionally, removing all vegetation would leave soil exposed and vulnerable to erosion, making these practices counterproductive for controlling soil erosion. Thus, focusing on effective land management strategies is vital for preventing soil erosion.
