A) Release of Neem oil in the soil increases nitrogen fixation by the soil microorganisms
B) Neem coating slows down the rate of dissolution of urea in the soil
C) Nitrous oxide, which is a greenhouse gas, is not at all released into atmosphere by crop fields
D) It is a combination of a weedicide and a fertilizer for particular crops
Correct Answer: B
Solution :
Spraying urea with neem oil slows the release of nitrogen, by about 10 to 15 per cent, concomitantly reducing consumption of the fertiliser. Many research studies in India have conclusively established that neem oil acts as an effective nitrification inhibitor if coated onto urea (ii) Spraying urea with neem oil slows the release of nitrogen, by about 10 to 15 per cent, concomitantly reducing consumption of the fertiliser. Hence B is the closet answer. Ref: Busienss Standard Newspaper/ New Delhi February 16, 2016; http://www.
