Nitrogen fertilizer - UREA is a major nutrient component in Agriculture and it is estimated that 50
- 70% of Urea is lost from the soil due to leaching, run off, volatilization and denitrification in field application.
To reduce the nitrogen loss and to increase the urea efficiency, Indian Scientists have conducted various research trials on different crops at different locations and concluded that when Urea is coated with Neem bitters, nitrogen loss reduces by 30-35% by
the leaching and denitrification. Yield increase upto 25% is also recorded.
The research reports have highlighted that, Neem coating of Urea is superior to other denitrifying coating agents like lac and Tar.
