Magnesium Sulfate Monohydrate Granules (MgSO₄·H₂O) are a high-purity, white granular form of magnesium sulfate monohydrate, processed through advanced granulation techniques to produce a uniform particle size with excellent fluidity, reduced dust, and ease of handling. This granular version maintains the chemical identity and properties of its powder form counterpart while offering superior performance in automated systems, precision agriculture, and industrial applications.
These granules are ideal for use in agriculture as a magnesium and sulfur fertilizer, in industrial processes requiring precise dosing, and in formulations where uniformity and low dust content are essential. With a magnesium (Mg) content of approximately 17.21% and sulfur (S) content of around 13.5%, this product serves as an efficient dual-nutrient source to improve plant health and optimize crop yield.
Magnesium is a core component of chlorophyll and plays a vital role in photosynthesis, enzyme activation, and nutrient uptake. Sulfur is essential for the synthesis of amino acids, vitamins, and proteins in plants. As a result, Magnesium Sulfate Monohydrate Granules provide balanced nutrition that promotes greener foliage, stronger stems, and improved crop quality.
In industrial applications, these granules are used in manufacturing flame retardants, textiles, paper, ceramics, and as a component in chemical synthesis. Their granular structure ensures better dispersion, reduced caking, and improved storage stability.
Free-flowing white granules with excellent solubility in water
High purity and consistent magnesium and sulfur content
Ideal for direct application or blending into NPK and compound fertilizers
Reduced dust for safer handling and cleaner application
Compatible with automated spreading and packaging systems
