Nano Urea (a fertilizer) has been approved by the government for commercial use because of its potential to substantially reduce the import bill, but several experts have questioned the science underlying its efficacy.
What is Liquid Nano Urea?
It is essentially urea in the form of a nanoparticle. Urea is chemical nitrogen fertilizer, white in colour which artificially provides nitrogen, a major nutrient required by plants.
