Molecular Formula:H3PO4.CO(NH2)2 Molecular Weight:158.06
CAS No.: 4861-19-2 EINECS NO.:225-464-3
Properties: Highly soluble in water (approx. 41g/100mL at 20°C), forming a strongly acidic solution. Decomposes above 110°C, releasing ammonia gas (NH₃) and phosphoric acid (avoid high-temperature drying). Aqueous solutions are highly corrosive.
Application:
1.Acidic soil amendment: As specialty Fertilizer, rapidly reduces soil pH (especially in saline-alkali land), activating iron/aluminum-fixed phosphorus.
2.Drip irrigation fertilizer: Combined with potassium fertilizers for chloride-sensitive crops (e.g., citrus, tobacco), preventing physiological phosphorus deficiency.
3.Foliar fertilizer enhancer:Improves pesticide adhesion (acidic environment enhances spray spreading performance).
Packing and storage: 25kg, 1000kg,1200kg net bag, store at a cool, dry and well ventilated place.
Shelf life: 3 years
