      How can we control soil pollution?

    Answer:

                      Following measures may be taken to control soil pollution: (i) Proper dumping of unwanted materials. (ii) Organic wastes contained in animal dung can be used for preparation of compost, manure and biogas rather than throwing them as waste and polluting the soil. (iii) Natural soil microorganisms should be used to increase the soil fertility rather than the use of pesticides and insecticides. (iv) To minimise soil pollution, waste such as paper, plastics, glass, metals, chemicals and industrial wastes should be recycled and reduced instead of throwing in the soil. (v) Use of chemicals, insecticides, etc., should be banned.
