1Following methods will be effective in the prevention of soil erosion - 

1. Afforestation is tree plantation, which should be undertaken in areas where plants/trees are already cut and additional areas should also be brought under plantation.

2. Crop rotation is cultivation of different crops in succession on the same area of land over a period of time. It maintains the fertility of the soil and the water-holding capacity of the soil. In this way it prevents soil erosion.

3. Strip-cropping is the planting of crops in rows or strips to check flow of water. It is a common practice on the sloping areas in hills, this reduces the steepness of the slopes and checks soil erosion.
