Urea is the major fertilizer used in the world as a nitrogen supplier which is a critical nutrient for crop growth. Urea contains highest nitrogen content. Urea is release Nitrogen in the soil and water and leached by activity of nitrifying bacteria Nitrobactor and Nitrosomonas. These bacteria turn nitrogen in nitrite and then nitrate which are highly mobile in nature when present in soil. By these processes approximate 50% of nitrogen provided by urea is lost. Neem Plus has proven nitrification inhibition properties. This way it slow down the process of nitrogen release from urea. It is the best nitrification inhibiting agent till date and better then sulpher. It slows down the process of nitrification of urea and save nitrogen.
