Sustained 150–200 day release
One application supports the full crop cycle, replacing multiple top-dressings of conventional urea.
Slow-Release Urea
Slow-release urea, done right — without microplastics.
Slow-release and controlled-release ureas were invented to stop the two-thirds of nitrogen normally lost to volatilization, leaching and runoff. UREGOLD's PNP coated urea takes the idea further: a Potassium Nitrophenolate coating that releases nitrogen across 150–200 days AND delivers a biostimulant effect — with no polymer microplastic load.
+24% NUE
More of every kilogram of nitrogen reaches the plant instead of the atmosphere or groundwater.
Up to 30% less urea
Match or beat conventional urea yields with significantly less nitrogen applied per acre.
Lower NH₃ & N₂O emissions
Reduces ammonia volatilization and nitrous oxide — the most potent agricultural greenhouse gas.
No microplastic load
Unlike polymer-coated urea, the PNP shell is a soluble, biodegradable Potassium Nitrophenolate — not plastic.
Built-in biostimulant
Released PNP and potassium drive germination, root growth and chlorophyll synthesis from day one.
Field-proven
When slow-release urea is the right choice
Slow-release urea pays off fastest on long-cycle, nitrogen-hungry crops and on soils prone to leaching.
- Paddy/rice — sustained N through tillering, panicle and grain fill
- Maize and wheat — uniform vegetative growth without late top-dress
- Sugarcane and cotton — long-cycle crops with high N demand
- Fruits, vegetables and horticulture — controlled feeding for quality
- Light/sandy soils where leaching losses are high
- Operations targeting fewer field passes and lower labor cost
