Soil is an important natural resource. It is a complex substance, which supports all plant life. We have limited soil on earth’s surface evolved through slow geological processes and matured by the interactions of climates and living organisms.
Productive soils and people at peace fit together, each nourishing the other. But one of the main problems of this technological era is associated with soil pollution through toxic substances. Also the excessive cultivation of crops and use of chemical fertilizers and pesticides etc., have badly affected the fertility of soils.
Soil pollution refers to lowering of its quality (disequilibrium stage) either due to heavy concentration of undesirable foreign elements through chemicalization or due to depletion of soil nutrients through accelerated rate of soil erosion.
