Nano urea is a nanoscale form of the conventional nitrogen fertilizer urea. Its reduced particle size increases surface area, promoting controlled release and improved nutrient uptake efficiency in plants. The gradual nutrient supply matches crop demands and mitigates environmental impacts by reducing nitrogen losses. Nano urea's potential benefits lie in enhanced agricultural productivity and sustainability, with reduced runoff and eutrophication risks. However, as a developing technology, its commercial availability and broader adoption require further investigation and understanding of potential long-term effects. Continued research is essential to ensure safe and effective utilization of nano urea in modern agriculture.
