A controlled-release engine, granule by granule.
UREGOLD (PNP Coated Urea) initiates a series of beneficial processes that deliver nutrients in a controlled, plant-aligned way.
Urea, encapsulated in a bioactive PNP shell.
Each high-purity urea granule is uniformly encapsulated with a proprietary potassium nitrophenolate (PNP) coating. The shell protects the nitrogen core from premature loss while delivering bioactive potassium and nitrophenol on contact with soil moisture.
- Pharmaceutical-grade blending
2-PNP, 4-PNP and 5-PNP blended at calibrated ratios for balanced bio-stimulation.
- Uniform encapsulation
Multi-stage drum coating ensures a defect-free, evenly thick PNP shell on every granule.
- Quality-controlled
Each batch validated by HPLC purity tests and release-rate assays before dispatch.
- STAGE 01
Moisture activation
After application, the PNP coating begins absorbing moisture from the atmosphere and the soil — the trigger that starts the controlled release.
- STAGE 02
Dissociation
The compound dissociates into its fundamental components: potassium and nitrophenol, made instantly available to the plant.
- STAGE 03
Bio-stimulation
Potassium powers enzyme activation, photosynthesis and protein synthesis. Nitrophenol breaks seed dormancy and drives early, uniform germination.
- STAGE 04
Sustained nitrogen release
The remaining urea releases gradually, providing a steady nitrogen supply over weeks — reducing leaching and maximizing uptake efficiency.
The result
Plants receive a consistent supply of nitrogen, potassium and growth-promoting nitrophenol — reducing the risk of nutrient leaching, improving nutrient use efficiency, and supporting sustainable, higher-yielding farming.
