Soil pollution can be controlled by limiting the use of chemical fertilizers and by substituting them with bio-fertilizers and manures. Reducing the use of pesticides and applying biological methods also reduces soil pollution.
Other methods to control soil pollution include recycling plastics, paper and other materials; reusing materials; promoting forestation and preventing deforestation; disposing wastes properly; and promoting pollution awareness programs.
Soil pollution is referred to as the contamination of soil caused by the presence man-made chemicals such as pesticides and insecticides. These chemicals tend to reduce the quality of soil making it less fertile or barren. Soil pollution is also caused by the alteration of natural environment. These causes arise from improper disposal of waste, agricultural chemicals and industrial activity.
Other causes of soil pollution include unfavorable irrigation practices; sanitary waste leakage; automobile fuel leakages; improper management and maintenance of septic systems; improper disposal of nuclear waste; poor waste management methods; and toxic fumes from industries that cause acid rains.
If soil pollution is not controlled, it can have adverse effects on the ecological balance and health of living organisms. These effects include increased soil erosion; creation of toxic dust; loss of nutrients in soil; reduced soil fertility; alteration in soil structure; and increase in soil salinity.
