Why does the Government of India promote the use of ‘Neem-coated Urea’ in agriculture?
Detailed Explanation:
✅ Statement 2 – Correct: Neem coating acts as a nitrification inhibitor, slowing down the conversion of urea to nitrate, thereby reducing nitrogen losses through leaching, volatilization and denitrification, and ensuring gradual nitrogen release for better crop uptake.
❌ Statement 1 – Incorrect: Neem coating does not enhance nitrogen fixation by soil microorganisms; it primarily inhibits nitrification.
❌ Statement 3 – Incorrect: While neem-coated urea reduces nitrous oxide emissions by minimizing denitrification, it does not eliminate greenhouse gas release completely.
❌ Statement 4 – Incorrect: Neem-coated urea is not a weedicide-fertilizer combination; neem acts as a nitrification inhibitor, not a weedicide.
