PRODUCT DETAILS
Product Introduction
Kieserite is a naturally occurring magnesium sulphate monohydrate (MgSO₄·H₂O) fertilizer that contains 16% magnesium oxide (MgO) and 20–23% sulfur (SO₃). It is available in granular and powder forms and is widely used in agriculture to correct magnesium and sulfur deficiencies in crops and soils.
Kieserite is fast-acting, 100% water-soluble, and chloride-free, making it ideal for a wide range of crops, particularly in acidic and light soils, or regions where magnesium leaching is common.
Key Benefits of Kieserite
- Supplies two essential secondary nutrients: magnesium and sulfur
- Promotes chlorophyll production, photosynthesis, and protein synthesis
- Enhances crop quality, yields, and disease resistance
- 100% chloride-free – safe for sensitive crops
- Powder form is ideal for blending or direct application, while granular form is suited for mechanical spreading and bulk blending
