On-site Consequences of soil erosion
- Loss of fertile soil- loss in soil productivity
- Loss of top soil: soil left behind has lower water-holding and cation exchange capacities, less biological activities
- Dense crust, reduces water infiltration, increases water infiltration,
- Fruits and foliage may be damaged by sandblasting effect
Off-site consequences
- Sedimentation, pollution, flood can be included under off site consequences.
- it creates the water pollution as well as lakes and rivers.
- cause eutrophication by excess of nitrogen and phosphorus.
- Blowing sand may bury roads and fills drainage ditches.
- Soil particles may damage fruits and foliage as well as paints on vehicles and buildings.
