Soil erosion is the natural process in which the topsoil of a field is carried away by physical sources such as wind and water. Soil erosion can be controlled by the following measures:
Plant trees on barren lands to limit erosion of soil.
Add mulch and rocks to prevent the plants and grass underneath to prevent soil erosion.
Mulch matting can be used to reduce erosion on the slopes.
Put a series of fibre logs to prevent any water or soil from washing away.
A wall at the base of the slope can help in preventing the soil from eroding.
