Question 9
Explain how soil pollution and soil erosion could be prevented.
The removal of soil from the surface of the land by the action of wind, water or ice is called soil erosion. The dumping of man-made waste or chemicals into the land decreases the fertility of the soil. This leads to soil pollution.
Steps for preventing soil pollution and soil erosion:
(i) Plantations should be encouraged because the roots of plant firmly bind the soil and help in preventing erosion.
(ii) Methods like crop rotation and mixed farming should be followed.
(iii) Use of organic fertilisers and manure instead of synthetic fertilisers should be encouraged.
(iv) Pesticides and insecticides should be used in limited quantity and find a natural way to prevent it.
(v) Plastic bags should be banned as they don't decompose and leads to soil pollution.
(vi) Industrial waste shouldn't be dumped directly as it kills necessary microorganisms of soil.
