SOP 0-0-50 Fertilizer
Sulphate of Potash (SOP) is the premium potassium source for quality-focused agriculture. With 50% K2O and 18% sulphur, it delivers chloride-free nutrition that improves crop taste, color, shelf life, and oil content — critical factors for fruits, vegetables, tobacco, and other high-value crops.
Why Choose SOP 0-0-50?
SOP is the preferred potassium source for growers who prioritize quality over cost. Its chloride-free composition makes it essential for crops where chloride accumulation reduces market value.
