In the Indian Agriculture scenario where the crop production with chemical fertilizers is increasing day by day, and by this chemical fertilizer which if not properly utilized could be harmful to the soil nutrient and soil micro flora reserves in the soil, as a result the excessive use of fertilizer deplete crop growth and productivity can be compromised over a period of time. Cumulative depletion can decrease agriculture production, crop yield & soil fertility and lead to soil degradation.

Thus the alternative option is to balance the organic and inorganic (chemical) nutrient requirements of plants and hence the nutrient reserve in the soil is essential for maintaining high yield, soil micro flora & soil fertility.

Sustainable agriculture refer to farming system which meet organic and inorganic(chemical)form of nutrient that preventing environmental degradation and sustaining agricultural production over the long term soil fertility and higher productivity.
