Why does the Government of India promote the use of ‘Neem-coated Urea’ in agriculture?

Question

CollectorBabu · Accepted Answer

Correct Answer: Neem coating slows down the rate of dissolution of urea in the soil. Neem oil acts as a ‘nitrification inhibitor’ when coated on urea. By slowing down urea hydrolysis and nitrification, it allows a more gradual release of nitrogen, which can be used by the plant. Neem-coating increases nitrogen use efficiency. Also, since the urea action is prolonged, the plants stay greener for a longer time. The other impacts of Neem Coated Urea are: ● Improvement in soil health; ● Reduction in costs with respect to plant protection chemicals; ● Reduction in pest and disease attack; ● An increase in yield of paddy, sugarcane, maize and soybean ● Diversion of highly subsidized urea towards non-agricultural purposes negligible among farmers after the introduction of the mandatory policy of production and distribution of the only Neem coated urea.
