High Purity Ammonium Sulfate Nitrogen Fertilizer White Granules CAS 7783-20-2

Ammonium Sulfate (CAS 7783-20-2) is a high-purity straight nitrogen fertilizer containing 21% nitrogen and 24% sulfur, supplied as white to off-white free-flowing granules. It delivers readily available ammonium nitrogen for rapid crop uptake and essential sulfate sulfur for protein and oil synthesis. Beyond agriculture, it is also used in industrial fermentation, water treatment, flame retardant formulations, and leather processing.

• 21% ammoniacal nitrogen ensures quick green-up and vigorous vegetative growth.

• 24% sulfur corrects hidden sulfur deficiency, improving crop quality and stress tolerance.

• Low hygroscopicity and uniform granules allow accurate spreading and minimal segregation in blends.

• High solubility for immediate nutrient availability in soil solution.

• Direct application fertilizer for cereals, oilseeds, corn, pastures, and horticultural crops.

• Raw material in NPK and sulfur-enriched compound fertilizer manufacturing.

• Industrial uses: protein precipitation, flame retardant production, tanning, and water treatment.

• Dual nutrient supply reduces the number of field passes and application cost.

• Low heavy metal content meets stringent environmental and food safety standards.

• Consistent granule hardness and size ensure reliable performance in bulk blending and spreading equipment.
