PRODUCT DETAILS
Product Introduction
Potassium Sulphate (SOP) is a premium, chloride-free potassium fertilizer with a guaranteed analysis of 50% potassium (K₂O) and 18% sulfur (S). Also known as sulfate of potash, SOP is ideal for high-value, chlorine-sensitive crops such as fruits, vegetables, tobacco, and tea.
SOP provides two essential nutrients — potassium for yield and quality, and sulfur for protein synthesis and chlorophyll formation. Available in powder, granular, or soluble form, it is used in soil application, fertigation, and NPK fertilizer blending.
Benefits of Potassium Sulphate
- Supplies high-potassium without added chlorides – ideal for salt-sensitive crops
- Enhances sugar content, color, size, and shelf life of fruits and vegetables
- Improves plant resistance to drought, disease, and environmental stress
- Adds soluble sulfur, which is vital for protein and enzyme synthesis
- Low salt index – safe for greenhouse and open-field applications
- Suitable for alkaline, saline, or sulfate-deficient soils
