Which of the following practices can help prevent soil erosion?

Conservation tillage is a beneficial practice that significantly helps prevent soil erosion. This method involves minimizing the disturbance of soil during planting and maintenance, which allows for the retention of soil structure and organic matter. By leaving a portion of the previous year’s crop residue on the surface, conservation tillage protects the soil from the impact of rain and wind, reduces runoff, and enhances water infiltration. This not only prevents erosion but also improves soil health and promotes sustainable farming practices.

In contrast, practices like intensive tillage disturb the soil more thoroughly, increasing the risk of erosion as the protective cover provided by residues is removed. Increased irrigation can lead to waterlogged conditions which may also contribute to soil erosion if not managed properly. Urban development often involves removing vegetation and altering the land surface, which can exacerbate erosion by increasing runoff. Thus, conservation tillage stands out as an effective method for soil erosion prevention.
