उत्तर
Soil pollution usually results from the disposal of solid and semi-solid wastes in agricultural practices, industrial processes and insanitary habits.
Some Major Causes of soil pollution:
Industrial waste: Industrial wastes are mainly discharged from coal and mineral mining, metal processing and engineering industries.
Agricultural practices: Though fertilizers are used to increase the fertility of soil, they often contaminate the soil with impurities present in them. When the fertilizers are contaminated with other synthetic organic chemicals, the soil water gets polluted.
