Performance of slow release hydroxyapatite coated urea nanofertilizer on aerobic paddy

These methods have lengthy process and difficult to scale up, hence a simple method of nanofertilizer production amenable for large scale production and testing its applicability in crop production can help for upscaling this futuristic technology. With this background, research was undertaken to synthesize urea coated hydroxyapatite nanofertilizer for enhanced nitrogen use efficiency and its filed testing using aerobic rice as test crop.
