        abstract = {The increasing global demand for food production has intensified reliance on synthetic fertilizers, leading to soil degradation, nutrient imbalance, environmental pollution, and loss of beneficial soil microbiota. Sustainable nutrient management strategies are urgently required to ensure long-term agricultural productivity without compromising environmental health. Nano biofertilizers have emerged as an innovative solution by integrating nanotechnology with beneficial microbial inoculants to enhance nutrient delivery efficiency and soil biological activity. These advanced formulations utilize nanocarriers to encapsulate nutrients and microorganisms, enabling controlled release, reduced nutrient losses, and improved plant uptake. Evidence from recent studies indicates that nano biofertilizers enhance soil physical structure, chemical balance, and enzymatic activity while promoting root development, photosynthetic efficiency, and stress tolerance in crops. Despite promising agronomic and environmental benefits, concerns regarding production costs, regulatory frameworks, and long-term ecological safety remain. This review synthesizes current knowledge on the mechanisms, applications, and agronomic significance of nano biofertilizers in improving soil fertility and crop yield while highlighting challenges and future research directions.},
