Continuous use of chemical fertilizers without organic sources poses soil health issues whereas organic manures using alone without inorganics could not be able to fulfill the requirement of high nutrient demanding crops due to the bulk and slow-acting nature of these organic fertilizer sources. However, neither organic fertilizers nor inorganic fertilizers alone can maintain productivity. The major yield limiting factors in crops production in Indian soils are NPS deficiencies. So, the option is to concentrate on alternate system like integrated nutrient management to maintain the productivity of soils where INM is promising strategy that aims to achieving harmony in the conjoint use of all resources like organic manures, bio-fertilizers, vermicompost, chemical fertilizers and other non conventional sources of plant nutrients.
