Potash with Sulfur (Sulfate of Potash – SOP) – Chloride-Free Potassium & Sulfur Fertilizer
📝 Product Description
Potassium Sulfate (K₂SO₄), also known as Sulfate of Potash (SOP), is a premium fertilizer that provides plants with essential potassium and sulfur in a highly soluble, chloride-free form. It’s especially suited for chloride-sensitive crops such as tomatoes, grapes, berries, potatoes, and ornamentals. Its dual nutrient profile supports flowering, fruiting, stress resilience, and superior crop quality.
🌿 Key Benefits
Supplies 50% K₂O and 18% sulfur (SO₃) in a water-soluble form
Chloride-free, making it ideal for chloride-sensitive crops and soils prone to salinity
Enhances transpiration regulation, enzyme activity, and protein synthesis, boosting stress tolerance and yield
Improves fruit size, color, taste, and shelf life, particularly in high-value crops
Low salt index, safe for high EC soils and greenhouse fertigation systems
💧 Application Guidelines
Applicable via soil, fertigation, or foliar spray:
Soil Application:
10–30 kg/ha for vegetables, fruits, and field crops depending on soil test results
Fertigation (Drip Irrigation):
5–10 kg/ha per application cycle for greenhouse and precision systems
Foliar Application:
1.5–3 g/L (or 5–10 kg/ha equivalent). Use fine-particle SOP (<0.015 mm) for good solubility; test on a few leaves before widespread application to avoid leaf burn.
⚠️ Safety & Handling
Store in a cool, dry place, sealed and away from moisture to prevent caking.
Use gloves and protective eyewear during handling to avoid dust inhalation or contact.
Avoid overconcentration in foliar sprays, as high sulfur levels may cause phytotoxicity in some sensitive plants
