Slow and Control Release Fertilizers

Neelam Aqua & Speciality Chem is manufacturing speciality coatings for nitrogenous fertilisers. These coatings help in slow release of nitrogen for urea, ammonium nitrate , Calcium ammonium  nitrate etc.

Slow & Controlled release can be achieved by urease & nitrification inhibitors manufactured by NEELAM AQUA & SPECILITY CHEM, Some of them are: -

  1. NBPT (N-(n-butyl) thiophosphorictriamide )

  2. DMPP (3,4 dimethyl pyrazole phosphate )

  3. DCDA ( Dicyandiamide )

  4. Neem Oil


  1. Liquid formulation so easy to use, gives maximum coating to Urea granules.

  2. High Active content which increases the efficacy.

  3. Highly stable and Environment friendly Solvents. A safe & Green Product to use.

  4. Pleasant Odour.

  5. Works even at low temperatures.


  1. Neelam Aqua & Speciality Chem is an ISO:9001 company.

  2. The Company  firmly believes in supplying quality products.

  3. In addition to the chemical analysis, the products also undergoes simulated performance tests.

  4. Field studies suggest that NBPT with urea has performed with success on a variety of crops, such as corn, wheat, cotton, rice, maize and barley.

  5. Tests have been conducted with NEELCOAT 1N 1000 for the controlled release.



Research suggests NBPT-treated urea use can reduce ammonia loss by 50% to 90% when compared to untreated urea. The potential boost in crop yield from the preserved N will depend on the nutrient demand of the crop, the indigenous soil N supply and other management practices. Urease inhibitors provide farmers with an additional tool to keep applied N in the root zone, which can have agronomic and environmental benefits.




Nitrification inhibitors delay the bacterial oxidation of the ammonium ion (NH4+) by depressing over a certain period of time (four to ten weeks) the activity of Nitrosomonas bacteria in the soil. These bacteria transform ammonium ions into nitrite (NO 2–), which is further transformed into nitrate (NO3 –) by Nitrobacter and Nitrosolobus bacteria. The objective of using nitrification inhibitors is to control the loss of nitrate by leaching or the production of nitrous oxide (N2O) by denitrification from the topsoil by keeping N in the ammonium form longer and thus increasing N-use efficiency. Furthermore, nitrification inhibitors – by delaying the conversion of ammonium to nitrate – avoid undesirable high nitrate levels in plants used for human and animal nutrition.

“Neem Oil “is a proven nitrification inhibitor. It slows down the process of nitrogen release from Nitrogenous Fertilisers. It is the best nitrification inhibiting agent available till date.
