Measures to prevent soil pollution:-

Soil pollution refers to the degradation of soil.

Drainage management:- It involves treatment of natural water channels such as drains.

Excessive irrigation to fields:- Excessive irrigation leads to water logging and it leads to desalination of soil of fields.

Excessive use of fertilizers:- This makes the soil brittle and the soil susceptible to erosion, it provides temporary fertilizer to soil and make it bad soil.

Measures to prevent soil erosion:-

Soil erosion refers to the displacement of top layer of soil.

Contour plowing:- Running the plow parallel to the contour lines on the sloping land, it reduces the speed of water flow which cause soil erosion.

Step farming:- The flow of water can be reduced by making a ladder on high sloping land. It reduces soil erosion.

Tree plantation:- The roots of the plants prevent soil, reducing soil erosion.

Controlling over grazing:- Soil erosion can be prevented by preventing uncontrolled grazing of animals.
