What it is / When to use

Low-chloride potassium-sulphur source for quality crops

Potassium Sulphate is a water-soluble potassium fertilizer raw material, K2SO4, CAS 7778-80-5, supplying typically K2O 50-52% and S 17-18% with chloride kept at Cl ≤1.5%. Also called Sulphate of Potash (SOP), RunziChem exports it as a low-chloride potassium source for chloride-sensitive crops and fertigation.

  • What it is Potassium sulphate (Sulphate of Potash, SOP), K2SO4, CAS 7778-80-5, white to off-white powder.
  • When to use Use it as the potassium source for chloride-sensitive crops such as tobacco, potatoes, grapes, citrus, and vegetables, and where sulphur is also required.
  • Honesty note specifications are industry-typical values for evaluation; final values are confirmed per batch COA.

Applications

Where Potassium Sulphate fits

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

Potassium + sulphur supply

Delivers K2O 50-52% potassium together with S 17-18% sulphate sulphur in one raw material.

Chloride-sensitive crops

With Cl ≤1.5% it suits tobacco, potatoes, grapes, citrus, and other chloride-sensitive fruit and vegetable crops.

Fertigation & foliar

Water-soluble powder dissolves for drip fertigation and foliar spraying, and it is also used in dry blends.

Water-soluble powder

White to off-white powder grade; the exact grade and solubility are confirmed per inquiry.

Compare with NOP / MKP

For nitrate-plus-potassium compare Potassium Nitrate (NOP 13.5-0-46); for a chloride-free phosphorus-potassium base compare MKP 0-52-34.

Buyer FAQ

Potassium Sulphate questions

When should I choose potassium sulphate (SOP) instead of potassium chloride (MOP)?
Choose potassium sulphate (SOP) when the crop is chloride-sensitive — such as tobacco, potatoes, grapes, citrus, and many fruits and vegetables — or when sulphur is also needed. SOP supplies K2O 50-52% plus S 17-18% with Cl ≤1.5%, while MOP carries high chloride. Choose MOP only for chloride-tolerant crops that can accept a chloride-based potassium source.
Is RunziChem potassium sulphate suitable for fertigation and foliar application?
Yes. The water-soluble powder grade of potassium sulphate (K2SO4, K2O 50-52%) dissolves for drip fertigation and foliar spraying, and it is also used in dry bulk blends. Because chloride is low (Cl ≤1.5%), it suits salinity-sensitive and drip programs. Confirm the exact solubility and grade per inquiry for your irrigation system.
What are the typical potassium and sulphur figures for potassium sulphate?
RunziChem potassium sulphate is a water-soluble SOP with typical K2O 50-52%, S 17-18%, and Cl ≤1.5%, supplied as a white to off-white powder (K2SO4, CAS 7778-80-5). These are industry-typical values for buyer screening; the exact grade and origin are confirmed per inquiry.
Are the potassium and chloride values guaranteed?
No. The figures shown for potassium sulphate, such as K2O 50-52% and Cl ≤1.5%, are industry-typical values for buyer screening. The current batch certificate of analysis (COA) confirms the final potassium content, sulphur content, chloride, moisture, and appearance for the lot you receive.
