Our magnesium sulfate fertilizer is a high-purity agricultural nutrient supplement, available in monohydrate (MgSO4·H2O) and heptahydrate (MgSO4·7H4O) forms. As a water-soluble mineral fertilizer, it efficiently delivers magnesium (Mg²+) and sulfur (SO4²-)-two critical elements for plant metabolism. The product is processed through advanced crystallization technology, ensuring uniform particle size and easy absorption by crops via soil or foliar application. It is free from harmful heavy metals, making it suitable for both conventional and organic farming.
