Question

what are major five reasons for soil erosion?

Answer 1

1. Soil Texture:

Small grain and open structure soil erodes more than the larger grain and closed structure soil.

2. Ground Slope:

Steeper slope ground erodes more than the ground having mild slope due to increased speed of run off than infiltration.

3. Intensity and amount of rainfall:

More the intensity of rainfall more will be the soil erosion.

4. Mismanaged utilization of soil resources:

The soil erosion is enhanced by improper surface drainage, removal of forest litter, overgrazing etc.

5. Distribution of rainfall and landscape:

If the ground surface is such that rainfall distributes evenly, there is not plenty rainfall, the erosion will be less.

6. Deforestation:

It is one of the major factors responsible for Soil erosion. Removal of forest cover which function as a binder of the top layer of the soil with increasing land demand have resulted in enhancing extent of soil erosion.

Answer 2

soil erosion takes place due to following reasons:
1. deforestation
2. soil carried over by water , wind ,etc.
3. dams construction
4. floods
5. overgrazing
6.mining
7. over irrigation
