How is PNP coated urea different from regular urea?

Conventional urea releases nearly all of its nitrogen within a few days, with up to two-thirds lost to volatilization, leaching and runoff. PNP coated urea uses a Potassium Nitrophenolate shell with ~0.1 micron pores to release nitrogen gradually as the crop demands it — improving Nitrogen Use Efficiency (NUE) by up to 24%.

How much regular urea can PNP coated urea replace?

Field trials with TNAU and partners show that 0.7–0.8 kg of PNP coated urea typically replaces 1 kg of conventional urea while matching or exceeding yield, because more of the nitrogen actually reaches the plant.

Which crops is PNP coated urea suitable for?

PNP coated urea is effective across paddy/rice, wheat, maize, cotton, sugarcane, vegetables, fruits, pulses and oilseeds. Long-cycle and nitrogen-hungry crops typically see the largest yield uplift.

PNP Coated Urea

PNP coated urea — slow-release nitrogen with built-in biostimulant.

Q: What is PNP coated urea?

PNP coated urea is a controlled-release nitrogen fertilizer in which a high-purity urea granule is uniformly encapsulated with Potassium Nitrophenolates (2-PNP, 4-PNP and 5-PNP). The PNP shell delays nitrogen release and simultaneously delivers a biostimulant effect, so crops receive nitrogen across 150–200 days while losses to leaching and volatilization fall sharply.

UREGOLD PNP coated urea encapsulates high-purity urea inside a Potassium Nitrophenolate (PNP) shell. The result: nitrogen released across 150–200 days, sharply reduced leaching and volatilization, and a measurable yield uplift across paddy, wheat, maize, sugarcane and horticulture.

UREGOLD PNP coated urea granules — patented controlled-release nitrogen fertilizer

Up to 30% less urea

Replace 1 kg of conventional urea with ~0.7–0.8 kg of UREGOLD without compromising yield.

+24% Nitrogen Use Efficiency

Sustained release matches crop demand from germination through grain fill — fewer losses, more uptake.

150–200 day release window

One application supports the full crop cycle, replacing multiple top-dressings.

Built-in biostimulant

Released PNP and potassium drive germination, root growth, chlorophyll synthesis and tillering.

Lower cost per kg of N uptake

Higher uptake efficiency lowers the true cost of nitrogen actually used by the crop.

Lower environmental impact

Cuts NH₃ volatilization, N₂O emissions and nitrate leaching into groundwater.
