Answer 2

Soil Erosion :-

• Washing or blowing away of the top layer of the soil is called soil erosion.

• Top layer of soil is the most fertile because it contains the most organic, nutrient-rich materials.

• Soil erosion is caused by natural factors like rain, water, ice etc. or manual factors such as ploughing of the field. But it is also caused by man-made factors.

Common Man-Made Reasons of Soil Erosion :-

• Shifting cultivation
• Deforestation
• Overgrazing
• Jhum cultivation etc.

Impact of Soil Erosion :-

• Reduces the capacity os soil to hold water.

• Lower layers generally contain fewer nutrients than top layer, hence, soil erosion contributes to loss of nutrients.

• Water infiltration is reduced, which makes it harder it harder for the seedlings to break through the soil crust.

• Erosion does not remove topsoil uniformly over the surface of a field, which makes it impossible for a farmer to apply fertilizers and chemicals uniformly and obtain uniform results.
