The green revolution brought impressive gains in food production but with insufficient concern for sustainability. With the increasing demand in agriculture it has become important for us to increase the productivity by using various chemical fertilizers. But with the continued use of these products the soil has been affected badly because of the depletion in the essential minerals of the soil, decreasing soil fertility and rapidly declining production levels. Dependence on chemical fertilizers for future agricultural growth would mean further loss in soil quality, possibilities of water contamination and destruction of soil biota. So to overcome this problem it has become important for all of us to use a different remedy. In nature, there are a number of useful soil microorganisms which can help plants to absorb nutrients known as bio-fertilizers. Their utility can be enhanced with human intervention by selecting efficient organisms, culturing them and adding them to soils directly or through seeds.
Key words: Bio-fertilizer, Chemical Fertilizer, Productivity.
