Product Detail
Potassium Sulphate (SOP)
K2SO4 water-soluble raw material, K2O 50-52%, S 17-18% and Cl ≤1.5%, a low-chloride potassium source for chloride-sensitive crops. Values are industry-typical and confirmed per batch COA.
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.
- Specification note figures are typical, not guaranteed; the batch COA gives the binding values.

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.
