Urea is the major source of nitrogenous fertiliser used in Agriculture. It is estimated that out of the total quantity of urea applied to crops, about 50- 70% is lost in various forms, thereby reducing the availability of nitrogen to crops. There is an age old practice in India of blending neem cake with urea. Based on this principle is our Urea coating agent NEEM UCA, a concentrated easy to use formulation. When NEEM UCA is coated on urea, it forms a fine coating and protects the loss of Nitrogen by denitrification ensuring regulated continuous availability of nitrogen for a longer period, as per the requirement of crops.
Mode of Action: When uncoated urea is applied to the soil, the urea (Amide) nitrogen is rapidly converted to ammoniacal nitrogen and subsequently to nitrite and nitrate forms. Nitrogen in these forms, besides being absorbed by plants, is also rapidly lost from the soil due to leaching, run off, volatilization and denitrification. When NEEM UCA coated urea is applied to soil, the neem triterpenes inhibit the activity of nitrifying bacteria resulting in delayed transformation of ammoniacal nitrogen into nitrite nitrogen. This ensures slow and continuous availability of nitrogen matching the requirements of crop plant during their life cycle.
Benefits: (1) Ready to use, economical and easy to apply. (2) Ensures slow and continuous availability of nitrogen to crops. (3) Reduces nitrogen loss from urea due to leaching and denitrification. (4) Protects crops from soil borne pests.
Method of Application: (1) Spread 50 Kg urea in the shade on a clean surface. (2) Mix evenly 250 gm NEEM UCA ensuring proper spreading on urea. (3) Rub urea NEEM UCA thoroughly by hand to get a uniform coating. For larger quantities of urea, suitable mixers can be used. (4) Allow coated urea to dry till it is free flowing and ready to use.
