Which practice helps prevent soil erosion?

• A. Applying high quantities of water
• B. Covering the soils
• C. Using pesticides
• D. Planting annuals only

Answer: (B)

Covering the soils is an effective practice for preventing soil erosion. When soil is left exposed, it is highly susceptible to erosion from wind and water. Covering the soil with organic materials, such as mulch, or establishing a vegetative cover helps to protect the soil surface, reducing the impact of raindrops on the soil, and limiting the ability of wind to displace soil particles. This coverage not only helps to mitigate erosion but also enhances soil health by adding organic matter.

In contrast, applying high quantities of water may lead to increased runoff, which can actually contribute to erosion rather than prevent it. Using pesticides does not address soil erosion and can sometimes worsen soil health issues, making erosion more likely. Planting annuals only can provide temporary ground cover, but they may not be as effective as a perennial system in maintaining soil stability over time, as they need to be replanted each year. Therefore, covering the soils is the most reliable method for erosion prevention, creating a stable environment that supports the soil structure.
