Agricultural-grade Magnesium Sulfate Heptahydrate powder (chemical formula MgSO₄・7H₂O) is a water-soluble magnesium-sulfur supplement fertilizer specifically developed for agricultural planting. Processed using a refined pulverization process, it boasts core advantages such as rapid dissolution, excellent dispersibility, high nutrient utilization, and convenient application. It quickly replenishes the two essential elements of magnesium and sulfur required for crop growth, making it suitable for large-scale planting of field crops, cash crops, fruit trees, and vegetables. It is the preferred fertilizer for modern agricultural fertigation and refined planting practices.

Four Core Benefits:
· 1.Promotes Photosynthesis: Magnesium is a core component of chlorophyll. Supplementation enhances crop photosynthesis, reduces yellowing leaves and premature aging, resulting in lush green leaves and robust growth.
· 2.Improves Resistance: Sulfur participates in the synthesis of crop proteins and enzymes, while magnesium promotes nutrient absorption and conversion. Their synergistic effect enhances crop resistance to drought, cold, and pests, reducing pesticide use.
· 3.Improves Product Quality: Promotes the accumulation of nutrients such as sugars, vitamins, and amino acids, resulting in more uniform fruit enlargement, brighter color, and better taste. For example, it increases the sweetness of fruits and vegetables, reduces fiber in vegetables, and increases the thousand-grain weight of grains.
· 4.Prevents Deficiency Symptoms: Quickly alleviates problems caused by magnesium deficiency, such as yellowing leaves (interveinal chlorosis), slow growth, and flower and fruit drop. It is especially suitable for supplementing crops with high magnesium requirements in the mid-to-late stages of growth.
Procurement Advantages
