Integrated nutrient management (INM) is a concept, which aims at the maintenance of soil fertility, sustaining agricultural productivity and improving farmer’s profitability through combined use of fertilizers, organic manures and bio-fertilizers. Cropping system is one of the important components of sustainable farming system as it serves as a component of INM, for sustaining the productivity of the system through efficient nutrient cycling. Therefore, balanced fertilization must be based on the concept of the cropping system rather than a crop, so that productivity of a system as a whole is sustained. In Indian agriculture there is mismatch between nutrient additions thorough fertilizers and nutrient removals by crops and resulted a net negative balance of 10 million tones (Mt) of NPK. To minimize India’s current annual negative nutrient balance, increased use of fertilizers along with organic manures would be essential and inevitable. Results of the long-term experiments on INM showed that the application of organic manures in conjunction with recommended does of N increased the productivity of different cropping systems(pearl millet-wheat, wheat-cotton, mustard-cotton, mustard-sorghum(fodder) and rice-wheat) followed in India. In addition to yield gains, integrated use of organic manures and fertilizer increased the organic C and nutrients content of the soil under various cropping systems tested. It is not only the higher productivity and maintenance of soil fertility but is also economical and the benefit : cost ratio of FYM use ranged between 2.07 to 10.02 in different cropping systems. An attempt has been made in this paper to asses the role of INM in maintaining soil health and crop productivity in Indian agriculture.
