SOP 51-17.5 is a highly concentrated, premium-grade Sulphate of Potash fertilizer designed to deliver optimal nutrition without the risk of chloride toxicity. Featuring a powerful blend of 51% Soluble Potash (K₂O) and 17.5% Soluble Sulphur (S), this formulation is highly valued for its exceptional purity and rapid water solubility, making it ideal for both drip irrigation (fertigation) and foliar spraying. By supplying readily available potassium, it drives crucial plant processes like carbohydrate transport, enzyme activation, and cellular water regulation, which directly improves fruit size, color, sweetness, and post-harvest shelf life. Simultaneously, the high sulphur content enhances nitrogen efficiency and protein synthesis. Because it is virtually chloride-free, SOP 51-17.5 serves as the safest choice for high-value, salt-sensitive cash crops—such as potatoes, tobacco, fruits, and leafy vegetables—while actively boosting the plant's natural defense mechanisms against drought, frost, heat, and disease.
