N-GUARD is a unique oleoresin formulation based on a blend of five different natural materials, including biologicals. It helps maximize the Nitrogen Use Efficiency of nitrogenous fertilizers like Urea, while minimizingthe loss of Nitrogen by virtually eliminating the risk of volatility, nitrification and leaching. The Epinimbin in N-GUARD has maximum nitriļ¬cation inhibition potency followed by Desacetylnimbin, Salannin, Desacetylsalannin, Azadirachtin and Nimbin.

A large percentage of the Nitrogen in nitrogenous fertilizers such as Urea is lost due to the action of nitrifying bacteria and ammonification This leads to ow fertilizer use efficiency and also proves to be an environmental hazard because of nitrate leaching.

What happens to Nitrogen post-application?

  • When Urea is applied to the soil only approximately 33% is actually utilized by the plant. Once applied, Urea hydrolyses rapidly to Ammonium Carbonate. This Ammonical form of Nitrogen is subsequently converted to Nitrite (NO2)and then to Nitrate(NO3) by the action of nitrifying bacteria viz. Nitrosomonas and Nitrobacter respectively. The processes of hydrolysis and nitriļ¬cation of Urea "fertilizer is, to a large extent, completed in about 15-20 clays under conducive agro-climatic conditions, 51,-‘Ce tha duration of most cultivated crops extends beygnd 9O_ 100 days, nitrates formed as a result of the relatively rapid hydrolysis and nitrification of Urea - being highiy soluble and in excess of the limited quantities required by crops at their early stages of growth - are liable to leach beyond the active root zone.
  • Therefore, apart from being directly responsible for a huge monetary loss, it is also an underground environmental hazard through nitrate leaching and ammonification. This gives rise to ground water contamination which poses a serious threat to the environment and human health. This problem can be considerably alleviated by treating such nitrogen fertilizers  with N-GUARD.
  • In order to ensure the continuous and optimal supply of Nitrogen to match the requirements of crOP5 at different stages of growth it is necessary t0 Iegulate the Nitrogen Supply to crops by slowing " the late of hYdF0lysis or nitrification or both.
  • The antibacterial properties of Neem have been found to help nitrification inhibition. We significance of Neem in increasing fertilizer Nitrogen efficiency has been studied extensively. Results of the effect of Neem coating or blending of prilled Urea are available from a large nurnber of experiments on several crops. Experiments on rice, in which losses of nitrogen are reported to be the most, reveal that the increase in rice yield due to Neem coating/blending of prilled urea ranged from 0.9% to 54.2%.
