Detailed explanation-1: -The roots of the plants bind the soil together, and interweave with other roots, forming a more solid mass that is less susceptible to both water and wind erosion. The removal of vegetation increases the rate of surface erosion.

Detailed explanation-2: -Vegetation intercepts rain, reducing its energy and preventing splash erosion. It also slows runoff, reduces sheet erosion, and anchors and reinforces the soil with its root system. Figure 2 shows how erosion rate decreases as the soil is covered by vegetation.

Detailed explanation-3: -You can reduce soil erosion by: Maintaining a healthy, perennial plant cover. Mulching. Planting a cover crop – such as winter rye in vegetable gardens. Includes annual grasses, small grains, legumes and other types of vegetation planted to provide a temporary vegetative cover.

Detailed explanation-4: -Soils most susceptible to erosion are those with the largest amount of medium (silt)-size particles. Clay and sandy soils are less prone to erosion. 4) Ground slope – its combined length, grade, and surface quality (rough or smooth) – affects erodibility.

Detailed explanation-5: -In return, vegetation, tree cover and forests prevent soil degradation and desertification by stabilizing the soil, maintaining water and nutrient cycling, and reducing water and wind erosion.
