Ever rising global population demands the production of more and more food grains. This increased demand has put up a pressure on the existing technologies and resources to produce more from the limited available resources. Thus, there is a need to increase the crop productivity from the ever-shrinking natural resources. The modern agriculture which comprises the utilization of high-yielding variety seeds, inorganic fertilizer inputs (primarily NPK fertilizers) and other plant protection chemicals have aided in increasing the agricultural production but at the cost of ruining soil, plant, and animal health. Moreover, this modern era agriculture is also challenged by declining cultivable lands, growing soil degradation, declining soil fertility, nutrient mining, and changing climatic scenarios. The use of these inorganic fertilizers has not reduced these challenges but have played quite a major role in aggravating them. Organic manures, on the contrary, do not harm the environment but also cannot provide all of plant’s nutritional demand. Thus, the growing concerns towards achievement of long-term sustainable production is under question. This directs our way to manage the declining resources smartly and by integrating various technologies. One such ecological approach is Integrated Nutrient Management which can offer as a potential technique for dealing with these issues. This chapter briefly describes about the idea of INM and its need, components of INM, and practices under integrated nutrient management along with the advantages and limitations in its adoption. INM has a diverse potential for improving plant performance and resource efficiency while also providing environmental and resource quality preservation. Advanced INM approaches enable fewer chemical fertiliser inputs and hence lower human and environmental costs (such as intensity of land usage, N use, reactive N losses, and GHG emissions) without affecting crop yields. As a nutshell, INM practise could be an innovative and environmentally favourable technique for global sustainable agriculture.
