Abstract

In this research work, commercially available neem oil coated urea prills were subjected to nitrogen release for 18 days in silty clay soil and the release was compared with nitrogen release from urea without neem coating. Neem oil coating enhanced urea hydrolysis to ammonia. Subsequent oxidation of ammonia to nitrates led to gradual rise of nitrate concentration, reaching maxima around 10th day followed by the drop in the concentration due to denitrification. It can be concluded that neem oil coating was able to retard nitrate formation by 27% at its maximum concentration and about 48% on an average based on the final concentration at the end of 18th day compared to urea without neem oil coating.
