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....


Control measures of soil pollution:Soil erosion can be controlled by a variety of forestry and farm practices.Ex: Planting trees on barren slopesContour cultivation and strip cropping may be practiced instead of shifting cultivationTerracing and building diversion channels may be undertaken.Reducing deforestation and substituting chemical manures by animal wastes also helps arrest soil erosion in the long term.
Proper dumping of unwanted materials: Excess wastes by man and animals pose a disposal problem. Open dumping is the most commonly practiced technique. Nowadays, controlled tipping is followed for solid waste disposal. The surface so obtained is used for housing or sports field.Production of natural fertilizers: Bio-pesticides should be used in place of toxic chemical pesticides. Organic fertilizers should be used in place of synthesized chemical fertilizers. Ex: Organic wastes in animal dung may be used to prepare compost manure instead of throwing them wastefully and polluting the soil.Proper hygienic condition: People should be trained regarding sanitary habits.Ex: Lavatories should be equipped with quick and effective disposal methods.Public awareness: Informal and formal public awareness programs should be imparted to educate people on health hazards by environmental education.Ex: Mass media, Educational institutions and voluntary agencies can achieve this.Recycling and Reuse of wastes: To minimize soil pollution, the wastes such as paper, plastics, metals, glasses, organics, petroleum products and industrial effluents etc should be recycled and reused.Ex: Industrial wastes should be properly treated at source. Integrated waste treatment methods should be adopted.Ban on Toxic chemicals: Ban should be imposed on chemicals and pesticides like DDT, BHC, etc which are fatal to plants and animals. Nuclear explosions and improper disposal of radioactive wastes should be banned.
