PRODUCT DETAILS
Product Introduction
GSOP 50%, or Granular Potassium Sulphate, is a high-quality, chloride-free potassium fertilizer containing 50% potassium oxide (K₂O) and 17–18% sulfur (S). Specially formulated in granular form for soil application, it is ideal for broadcasting, blending, and mechanical spreading.
GSOP is especially recommended for chloride-sensitive crops like tobacco, grapes, potatoes, and fruit trees, where chloride-free nutrition is essential for yield quality, taste, and storage life.
