When urea is applied to the soil, it is first hydrolysed or broken by water into ammonium ions (NH4+), followed by oxidation to nitrite (NO2-) and, then, nitrate (NO3-) forms. In normal urea, however, the conversion to nitrate happens very rapidly. As a result, up to two-thirds of the nitrogen is lost either through underground percolation (‘leaching’) of nitrates or ‘volatilisation’ (escaping into atmosphere).
Neem oil basically 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. Farmers apply urea when they notice the leaves turning yellowish.
