Abstract
Nitrogen Use Efficiency (NUE) is a key characteristic for sustainable agriculture to increase crop yield in parallel with reducing negative environmental impacts. Inm-Integrated Nutrient Management: Integrated nutrient management is an approach that integrates both organic and inorganic sources of nutrients & improves the productivity of crops and crop sustainability. Controlled release or stabilized nitrogen fertilizers better match plant needs with nutrient supply and reduce losses. Crop rotation and diversification approaches are used to improve NUE by maintaining soil fertility, pest management, and enhancing crop productivity. Organic amendments are essential in enhancing soil health and can serve as drivers of carbon sequestration as well as facilitate optimized nutrient cycling. There are challenges associated with NUE optimization, regardless of the sophistication of technology. The mentioned requirements are a better linkage between crop and livestock systems, development of more reliable NUE indicators, and adjusting precision farming for the sustainability. The path forward should concentrate on strategies that are innovative like improved crop sequences and sensor-based fertility management systems as well as an intensification which is sustainable. This group of problems required a high level of efficiency in nitrogen use as well as a decent performance of crops and mitigation of environmental degradation. Such holistic approaches combine the agronomic, genetic, and technologic dimensions into a long-term effort to conquer the exigencies of feeding the worldâs population without adversely affecting ecosystem health.
