Product Description

Potassium Sulphate (K₂SO₄) is a water-soluble inorganic salt belonging to the class of potassium fertilizers. It is typically produced through the reaction of potassium chloride with sulfuric acid or extracted from natural mineral deposits, resulting in a high-purity crystalline compound. Composed of potassium and sulfate ions, it provides both essential plant nutrients in a balanced, readily available form.

Potassium Sulphate is characterized by its white crystalline appearance, high solubility in water, non-hygroscopic nature, and chemical stability. It is non-toxic, odorless, and compatible with a wide range of other fertilizers and soil amendments. These properties make it highly valued for its ability to supply potassium and sulfur efficiently without introducing chloride, which can be detrimental to sensitive crops.

Potassium Sulphate is widely used in agriculture to enhance crop yield, improve fruit quality, and strengthen plant resistance to stress. It is suitable for fertigation, foliar sprays, and soil application, particularly in chloride-sensitive crops such as fruits, vegetables, and tobacco. Additionally, it finds applications in industrial processes as a raw material for glass manufacturing, chemical production, and specialty fertilizers.
