Urea is the major source of Nitrogenous fertilizer world-wide. However, a large part of the Nitrogen from Urea is lost and does not add to the nutrient value.
With the increasing cost of Urea production, it is becoming important to save and judiciously use every part of the urea prill. “Nitrogen from Urea is released in the soil and leached by the activity of nitrifying bacteria Nitrobacter and Nitrosomonas. These bacterias turn nitrogen in nitrite and then into nitrate which is highly mobile in nature when present in the soil. By these processes, approximate 50% to 65% of nitrogen provided by urea is lost. A solution to this problem of nitrogen loss from urea is to coat the area with “OAN NML”.
