✨ Enhance Fruit Quality, Plant Strength & Yield with Potassium Sulfate (SOP) 0-0-51 ✨
Give flowering and fruiting plants a concentrated potassium and sulfur boost during the stages when crop quality matters most. Our Potassium Sulfate (SOP) 0-0-51 is a premium, fully water-soluble plant nutrient designed to support fruit development, firmness, colour, flavour, plant strength, and overall yield. With 51% soluble potash and no nitrogen, SOP is especially useful during flowering, fruit filling, and ripening stages when plants require additional potassium without encouraging excessive leafy growth. It is also chloride-free, making it suitable for many chloride-sensitive crops.
🌱 Why Use SOP 0-0-51?
