Re-engineering of nanofertilizers for sustainable agriculture: synthesis, mechanistic insights, toxicity and regulatory frontiers

The green revolution enhanced global food production, ensuring food security for a rapidly growing population. However, overreliance on traditional fertilizers has led to environmental degradation and poor nutrient use efficiency. This necessitates a paradigm shift toward sustainable agriculture. Nanofertilizers are a frontier technology having the potential to overcome such challenges by optimizing nutrient delivery and reducing environmental footprint. This review critically assesses the mecha
