Recent agricultural practices i.e the use of fertilizers pesticides, herbicides and biocides etc. are employed to increase the soil fertility and crop production to feed an increasing population in a developing country like India. Excessive use of fertilizers by man is one of the major source of environmental pollution. Fertilizer enriched soil 1 cannot support microbe population. Hence, humus and essential micro and macro-nutrients become efficient in such soils. These soils become poor and can easily be eroded by wind and rain causing more damage to the ecosystem. Long term application of fertilizers on land has also created an adverse ecological effect
