⏪Soil Degradation is caused by the following factors :
↪Deforestation : Cutting down of trees on a large scale makes soil vulnerable to Erosion which further reduces its fertility and adversely affects its quality .
↪Over Irrigation : Though Irrigation of crops is necessary, irrigation more than required can be dangerous . It makes the soil highly alkaline and poor in basic nutrients .
↪Mining : the Process of Mining releases harmful substances. These prevent proper aeration of soil . Thus, the soil is deprived of basic nourishment.
↪Over Grazing : over grazing by animals exposes the soil to agents like wind rain etc thereby making it vulnerable to Erosion.
-----------------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------------
⏪Conservation of Soil :
↪Planting Trees on a large Scale [ Afforestation ]
↪Prevent Over grazing
↪Terrace Farming , ploughing along contour lines , Building Shelter belts .
↪Careful or Reduced Mining .
↪Proper Irrigation .

Causes of Soil Degradation and Methods for Soil Conservation
Major causes of soil degradation
- Soil erosion
- Decline of soil fertility
- Water logging
- Salinity
- Shifting cultivation
Soil erosion
- 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.
Soil conservation methods
- Afforestation.
- Contour ploughing (cultivation against the direction of the wind).
- Strip cultivation (cultivation in strips).
- Flood control by government initiatives.
- Reclamation of bad lands.
- Wind breaks in land; like trees at borders.
- Organic farming.
- Control/restrict shifting cultivation.
- Construction of proper drainage.
- Leveling of gullies, ravines etc.
- Control of chemical fertilizers and pesticides in the market.
- Proper awareness about the need of conservation.
Hope uhh get it.
