Liquid urea is cheaper than granular urea and may also be used for enhancing abiotic stress tolerance. The liquid nano urea consists of a higher surface area because of the lesser size of the nanoparticle and high reactivity and solubility in water. It is found effective in the nutritional quality of plants. It can reduce the excessive use of urea application to soil. It is very effective for precise nutrient management in precision agriculture by matching the crop growth stage for nutrients and may provide nutrients throughout the crop growth period. Liquid nano urea should be tested through on-farm trial and large-scale demonstrations.
