Specialized Production of Potassium Sulfate by Mihan Zaj
What is Potassium Sulfate?
Potassium sulfate is a mineral salt in the form of a white, crystalline powder or granule with high solubility in water. The primary significance of this fertilizer lies in its low salt index and its chlorine-free nature.
Unlike other potassium sources such as potassium chloride (KCl), potassium sulfate is an ideal option for use in saline and alkaline soils, as well as for chlorine-sensitive crops (such as pistachios, potatoes, tobacco, citrus fruits, and vegetables). The potassium it contains plays a key role in regulating plant water balance, activating enzymes, and increasing resistance to cold and diseases.
The Potassium Sulfate Production Process at Mihan Zaj Company
In line with its goals of completing its product portfolio and responding to the critical needs of the agricultural community, Mihan Zaj Company has made extensive investments in the production of potassium sulfate. After years of effort and overcoming economic challenges and sanctions, the company's Potassium Sulfate (SOP) production unit was commissioned in 2012, utilizing advanced Mannheim Furnace technology.
Production using the Mannheim process guarantees the highest purity and quality of the final product. At Mihan Zaj, we are committed to providing Iranian farmers with a premium quality product to enhance farm productivity, in strict compliance with national and international standards.
Key Applications of Potassium Sulfate (SOP)
While its primary application is in agriculture, this product is also used in other industries:
- Agriculture and Horticulture:
- Supplying the potassium and sulfur required by plants.
- The best option for hydroponics and drip irrigation systems (due to its complete solubility). - Ideal for saline and alkaline soils.
- Improving the quality, taste, color, and shelf life of horticultural and agricultural products.
- Used in the production of certain types of special glass.
- As a catalyst in some chemical processes.
- In the gypsum and construction materials industries.
Advantages of Mihan Zaj's Potassium Sulfate
- Very High Purity: Produced using the Mannheim process.
- Chlorine-Free: Suitable for all sensitive plants and prevents the accumulation of chlorine in the soil.
- Lowers Soil pH: Its sulfur content helps in the amendment of alkaline soils.
- Increases Plant Resistance: Significantly improves resistance to environmental stresses (frost, drought, salinity).
- Complete Solubility: Does not cause residue or clogging in irrigation systems.
Packaging and Storage
The potassium sulfate produced by Mihan Zaj Company is supplied in 25 kg and 50 kg laminated bags, as well as jumbo bags (available upon customer request). It is recommended that this product be stored in a dry, cool, well-ventilated area, away from moisture, heat sources, and incompatible chemicals.
