During and after the green revolution in last century, agrochemicals especially nitrogen (N) were extensively used. However, it resulted a remarkable increase crop yield but drastically reduced soil fertility; increased production cost, food prices, carbon footprints; depleted fossil reserves with huge penalties to environment ecological sustainability. The groundwater, rivers, oceans are loaded N excess which is an environmental catastrophe. Nitrogen emissions (e.g., ammonia, oxide, nitrous oxide) play important role global climate change contribute particulate matter acid rain causing respiratory problems, cancers, damage forests buildings. Therefore, nitrogen-polluted planet Earth needs concerted efforts avoid disaster. Improved agricultural management focuses on synchronization of demand supply along improving N-use efficiency crops. there very little focus natural sources available for plants form diazotrophic bacteria present inside or root surface rhizosphere. These diazotrophs mini-nitrogen factories that convert (78%) atmospheric N2 ammonia through process known as "biological fixation" then taken up by its metabolic functioning. Diazotrophs also stimulate architecture producing plant hormones hence improve plant's overall ability uptake nutrients water. In recent years, nanotechnology has revolutionized whole agri-industry introducing nano-fertilizers coated/slow-releasing fertilizers. With this mind, we tried explore following questions: To what extent can requirements be met diazotroph inoculation? Can input agriculture managed way leading benefits farmers saving money? help technological advancement application? review suggests integrated technology based slow-releasing nano-fertilizer combined should adopted decrease inputs system. This would minimize pollution losses much extent.
