Used in agriculture as a source of magnesium and sulfur for soil supplementation, especially in magnesium-deficient soils. It enhances chlorophyll production and supports healthy plant growth. Commonly applied in horticulture and crop farming, particularly for sensitive crops like potatoes, fruits, and vegetables where balanced nutrient supply is critical. Also utilized in some photographic processes and as a reducing agent in chemical synthesis. Its high solubility makes it suitable for foliar sprays and fertigation systems.
