Integrated nutrient management for sustainable crop production: A review

Meera Devi, Manju Kumari

The increasing food demands of a growing human population and the need for an environmentally friendly strategy for sustainable agricultural development require significant attention when addressing the issue of enhancing crop productivity. Here we discuss the role of integrated nutrient management (INM) in resolving these concerns, which has been proposed as a promising strategy for addressing such challenges. INM has multifaceted potential for the improvement of plant performance and resource efficiency while also enabling the protection of the environment and resource quality. A comprehensive literature search revealed that INM enhances crop yields by 8-150% compared with conventional practices, increases water-use efficiency, and the economic returns to farmers, while improving grain quality, soil health and sustainability. Lower inputs of chemical fertilizer and therefore lower human and environmental costs (such as intensity of land use, N use, reactive N losses and GHG emissions) were achieved under advanced INM practices without compromising crop yields.
