Which of the following practices helps in reducing soil erosion?

Implementing ground covers is an effective practice for reducing soil erosion. Ground covers, such as grasses or low-growing plants, provide a protective layer over the soil, which helps to hold the soil in place and prevent it from being washed or blown away by rain and wind. The roots of these plants bind the soil particles together, stabilizing the soil structure and reducing the impact of rainfall on the soil surface. This not only minimizes erosion but also helps improve soil health by maintaining moisture and enhancing nutrient retention.

Other practices, such as using chemical pesticides, do not address soil erosion directly and may even contribute to further degradation of soil health. Choosing high maintenance plants could lead to increased soil disturbance due to the maintenance activities required, which could exacerbate erosion rather than mitigate it. Allowing bare soil areas is counterproductive, as exposed soil is more vulnerable to erosion from rainfall and wind.
