Agriculture Fertilizer Granular Magnesium Sulphate Heptahydrate for Agriculture. Our Heptahydrate crystals provide a concentrated source of water-soluble magnesium and sulfur, delivering essential secondary nutrients to prevent micronutrient deficiencies in crops. Magnesium serves as the central atom of the chlorophyll molecule. It directly drives photosynthesis to correct leaf yellowing (chlorosis) and boost overall plant vigor. These transparent crystals exhibit high water solubility with zero residues. This makes them ideal for precise application through foliar spraying and modern drip irrigation systems. This agricultural-grade fertilizer facilitates carbohydrate and protein synthesis within the plant, significantly improving fruit sweetness, color, and shelf life for higher market value.
