Man has been responsible for disturbing the natural environment of the soil in various ways, through his domestic, agricultural, and industrial activities which have directly or indirectly polluted the soil.
Chief soil contaminants
(I) Areas around smelting and mining complexes are usually soiled by metals such as cadmium, zinc, lead, copper, arsenic, and nickel. These contaminants render plants unsafe for human and animal consumption.
(II) The major source of land pollution are the industries viz. pulp and paper mills, oil refineries, power and heating plants, chemical and fertiliser manufacturing units, iron and steel plants, plastic and rubber producing factories.
(III) Modern agriculture, through the non-judicious use of chemical fertilisers, insecticides, herbicides, and fumigants pave way for the heavy pollution for soil.
(IV) Household garbage, consisting of groceries, food scraps, vegetable remains, packing materials, cans, cartons, paper, ash, broken gadgets, wood, metals, plastics, ceramics, glass, and other junk contributes to the solid non-reusable rubbish.
