Potassium Sulphate (SOP), chemically known as K₂SO₄, is a premium, chloride-free potassium fertilizer containing 50-52% K₂O and 17-18% sulfur. It is the preferred potassium source for high-value, chloride-sensitive crops due to its ability to significantly enhance crop quality without the risk of chloride toxicity. SOP improves fruit size, sugar content, color, and shelf life while also providing essential sulfur for protein synthesis. Its excellent water solubility makes it ideal for fertigation and foliar application. SOP is indispensable in modern agriculture for maximizing the yield and marketability of cash crops, fruits, and vegetables.
