About Potassium Sulfate

Potassium Sulfate is a dual-nutrient fertiliser containing 50-52% K₂O and 18% Sulfur. Unlike standard potassium chloride, SOP is virtually chloride-free, making it indispensable for soil health in arid regions and for crops sensitive to salt stress. We utilise world-class manufacturing infrastructure employing the Mann...
