Potassium sulfate, also known as sulfate of potash (SOP), is a chemical compound containing potassium and sulfate ions. It is commonly used in agriculture as a high-potassium fertilizer, contributing essential nutrients for plant growth and development. Potassium sulfate dissolves easily in water, providing readily available potassium ions to plants without chloride, which can be harmful to certain crops. It promotes flowering, fruiting, and overall crop yield, particularly in potassium-deficient soils. Beyond agriculture, potassium sulfate is utilized in industrial applications such as glass manufacturing, where it reduces the melting point of silica and improves glass clarity. In pharmaceuticals, it serves as an electrolyte supplement due to its potassium content, supporting cellular functions in the human body. Potassium sulfate is valued for its versatility and beneficial effects across various sectors.
