amonium sulphate/ammonium sulphate N20.5%-21


Generally, it is a by-product from chemical (cyanuric acid, capro, acrylonitrile, sodium cyanide, monosodium glutamate – MSG, methyl methacrylate – MMA, etc.) or steel plant.


2.Category: typical inorganic nitrogen fertilizer.


best fast release, quick acting fertilizer directly for a variety of soil and crops. More efficiency than urea,

ammonium bicarbonate, ammonium chloride, ammonium nitrate.
