UTEC Stabilized Urea — NBPT-Inhibited 46% Nitrogen
Surface-applied urea on calcareous soils can lose 30–50% of nitrogen to ammonia volatilization within days. UTEC grade combines standard 46% N prills with NBPT urease inhibitor, extending the conversion window and improving nitrogen recovery in wheat, maize and pasture programmes. Granules 2–4 mm suit mechanical spreading and bulk vessel loading. Contract parcels from 1,000 MT to discharge ports across MENA, South Asia and East Africa.

Field Application & Logistics
UTEC performs best when broadcast onto moist soil or incorporated within 24 hours — the NBPT coating delays urease activity without altering the 46% N analysis. Bulk shipments move in 5,000–25,000 MT geared bulkers; bagged lots in 50 kg PP or 1,000 kg FIBC for inland distributors. FOB at nominated load port; CFR/CIF includes ocean freight to your terminal. HS 3102.10; mill COA and third-party inspection available on request.
FAQ
How does NBPT treatment change urea behaviour in the field?
NBPT temporarily blocks urease enzymes on the soil surface, slowing hydrolysis of urea to ammonium. This reduces ammonia gas losses when urea is not immediately incorporated — particularly on high-pH soils above 7.5 where volatilization is most severe.
Can UTEC be blended with DAP or MOP without losing inhibitor activity?
Yes. UTEC granules blend cleanly with standard NPK components in bulk blending plants. The NBPT coating remains effective through mechanical mixing; however, avoid prolonged storage in high-humidity conditions before application.
Is UTEC suitable for fertigation systems?
UTEC is primarily designed for solid application. For drip and pivot systems, standard urea or UAN solutions are typically preferred. UTEC can be used in dry fertigation setups where granules are dissolved in tank mixes, but dissolution is slower than untreated prilled urea.
