Major causes of soil degradation
Soil erosion
Decline of soil fertility
Water logging
Salinity
Shifting cultivation
Soil erosion:
Among the agents, water is considered as the main cause of soil erosion.
Main agents of soil erosion are (1) Water, (2) Wind, (3) Waves and (4) Glaciers
Removal of the top layer of soil by various means, which include both natural events and human activities, is called as soil erosion.
Water-caused soil erosion can be classified as below:
Sheet Erosion: Uniform removal of the top soil just like a sheet.
Rill Erosion: Heavy water flow cause rill in Land.
Gully Erosion: Rill will enlarge as Gullies and land will be disordered. ( eg: Chambal Valley)
Note: Wind erosion also causes sheet and rill erosions.
Note: The largest area affected by soil erosion in India is the State of Rajasthan followed Madhya Pradesh.
