Description
🌿 Potassium Sulfate Granular (K₂SO₄)
High-purity Potassium and Sulfur for Smart Agriculture
Potassium sulfate (K₂SO₄), also known as sulfate of potash (SOP) or arcanite, is a white, water-soluble inorganic salt manufactured with high quality by Urmia Petrochemical Company. It is one of the best options for simultaneously supplying potassium and sulfur—two essential nutrients—for agricultural crops.
✅ Key Benefits of Potassium Sulfate
- Chloride-Free: Ideal for chloride-sensitive crops such as tobacco, grapes, potatoes, and certain vegetables
- Boosts Productivity: Improves fruit quality and increases crop resistance to drought and diseases
- Compatible with Saline Soils: Excellent choice in areas with high chloride content in soil or irrigation water
- Quick Dissolution: Suitable for drip irrigation systems and foliar application

🔍 Key Differences Between Powdered and Granular Potassium Sulfate
| Feature | Powdered K₂SO₄ | Granular K₂SO₄ |
|---|---|---|
| Physical Form | Fine powder | Small granules |
| Main Application | Foliar spray, fertigation (drip systems) | Direct soil application |
| Dissolution Speed | Fast-dissolving | Slower, gradual release in soil |
| Nutrient Availability | Quick uptake by plants | Long-lasting effect in the soil |
| Dust Generation | Higher dust, less suitable for open handling | Low-dust, easier and cleaner to apply |
| Mechanical Spreading | Not suitable | Suitable for spreaders and machinery |
| Recommended Use | Greenhouses, precision irrigation systems | Field crops, orchards, conventional farming |
