Application

Descriptions:

• Potassium sulphate is the most popular low-chloride fertilizer.

• Combining Potassium (50% K2O) and Sulphur (18%), SOP offers a high concentration of nutrients readily available to plants.

• Potassium Sulphate has a very low salinity index making it the preferred potash fertilizer in areas at risk from soil salinity.

• SOP improves crop yield and quality, making plants more resistant to drought, frost, insects and disease.

• Potassium Sulphate not only improves the crop's nutritional value, taste and appearance but also its resistance to deterioration during transport and storage, and its suitability for industrial processing.

Uses:

• Mainly used as the raw material of blending NPK.

• Used as a specialty fertilizer on crops that are sensitive to soil chloride levels, also used in cases where chloride buildup may be problematic.

• Used as a flash reducer in artillery propellant charges. It reduces muzzle flash, flare back and blast overpressure.

• Used as an intermediate in dye industry.

• Used as a clarifying agent in glass industry.

• Used as a release inhibitor in medicine.

• Used as an accessory ingredient in aromatics industry.

• Used in biochemical inspection of serum protein.
