Nano-biofertilizers are an emerging innovation that integrates nanotechnology with beneficial microorganisms to enhance nutrient use efficiency and crop productivity. Conventional fertilizers suffer from significant nutrient losses, leading to environmental pollution and soil degradation. Nano-biofertilizers overcome these limitations through controlled nutrient release and improved microbial activity in the rhizosphere. They enhance nutrient uptake, reduce chemical fertilizer dependency and support sustainable agricultural practices. Despite challenges such as cost and limited awareness, nano-biofertilizers offer a promising approach for achieving efficient and environmentally sustainable agriculture.
