What it is / When to use

Nitrogen-sulphur raw material for blending and soil programs

Ammonium Sulphate is a crystalline nitrogen fertilizer raw material, (NH4)2SO4, CAS 7783-20-2, supplying typically N 21% in ammoniacal form and S 24% sulphur. It dissolves at roughly 76 g per 100 mL of water at 20°C, and RunziChem exports it as a nitrogen-sulphur source for blending and soil programs.

  • What it is Ammonium sulphate, (NH4)2SO4, CAS 7783-20-2, white to slightly yellow crystals.
  • When to use Use it as the nitrogen source in bulk-blend (BB) fertilizers, for nitrogen-plus-sulphur soil programs, and where an acidifying effect helps lower pH on alkaline soils.
  • Honesty note specifications are industry-typical values for evaluation; final values are confirmed per batch COA.

Applications

Where Ammonium Sulphate fits

Confirm crop, rate, compatibility, and local label requirements before application.

Nitrogen + sulphur supply

Delivers N 21% ammoniacal nitrogen together with S 24% sulphate sulphur in one raw material.

Bulk-blend (BB) nitrogen source

A standard crystalline nitrogen source for bulk-blend and compound fertilizer production.

Alkaline soil programs

Ammoniacal nitrogen has an acidifying effect that helps lower pH on alkaline and calcareous soils.

Caprolactam grade

White to slightly yellow crystals, commonly caprolactam-grade; exact grade is confirmed per inquiry.

Compare with MAP / SOP

Buyer FAQ

Ammonium Sulphate questions

When should I choose ammonium sulphate instead of urea as a nitrogen source?
Ammonium sulphate supplies N 21% in ammoniacal form plus S 24%, while urea carries about N 46% with no sulphur. Choose ammonium sulphate when the crop or soil also needs sulphur, when a crystalline nitrogen source is preferred for blending, or when a mild acidifying effect is useful on alkaline soils. Choose urea when nitrogen concentration per ton is the priority.
What grade and appearance does RunziChem ammonium sulphate have?
The commonly traded material is caprolactam-grade ammonium sulphate, supplied as white to slightly yellow crystals with typical N 21% and S 24%. These are industry-typical values; the exact grade, granulometry, and origin are confirmed per inquiry and per batch COA.
Can ammonium sulphate be used in bulk-blend (BB) fertilizers and fertigation?
Yes. Ammonium sulphate is a standard crystalline nitrogen source for bulk-blend (BB) and compound fertilizer production, and it is also applied directly to soil. With a solubility of roughly 76 g per 100 mL of water at 20°C it can be dissolved for fertigation, though fully soluble grades should be confirmed per inquiry for drip systems.
Are the nitrogen and sulphur values guaranteed?
No. The figures shown for ammonium sulphate, such as N 21% and S 24%, are industry-typical values for buyer screening. The current batch certificate of analysis (COA) confirms the final nitrogen content, sulphur content, moisture, and appearance for the lot you receive.
