India requires approximately 350 lakh tonnes of urea annually, with 40 lakh tonnes being imported. The government heavily subsidizes urea, selling a 45-kg bag that costs around ₹3,000 at ₹242 to farmers. In 2023-24, the government spent ₹1.3 lakh crore on urea subsidies. A conventional urea bag provides about 20 kg of nitrogen in a plant-usable form. Nano-urea contains 4% (w/v) nitrogen in its 500ml solution, equivalent to 20 grams of nitrogen - approximately one-thousandth of the nitrogen present in a conventional urea bag.
