With purity above 98%, AOLANSU Anhydrous Magnesium Sulfate provides concentrated magnesium and sulfur nutrients. Magnesium plays an essential role in chlorophyll formation and photosynthesis, while sulfur supports protein synthesis and enzyme activity. The balanced nutrient supply helps improve crop growth, leaf development, and overall plant health.
The product dissolves rapidly in water, allowing magnesium and sulfur elements to be efficiently delivered through soil application, fertigation, drip irrigation, or foliar spraying. Its high solubility makes it especially suitable for precision fertilization systems and modern intensive agriculture.
Compared with Magnesium Sulfate Heptahydrate, Anhydrous Magnesium Sulfate contains no crystal water and provides higher effective nutrient concentration. Under proper moisture-proof storage conditions, it offers improved transportation efficiency and easier inventory management.
AOLANSU Anhydrous Magnesium Sulfate can be used in various fertilizer formulations and industrial processes. It is compatible with many water-soluble fertilizers and can serve as a reliable magnesium and sulfur source for different production requirements.
AOLANSU adopts standardized production processes to manufacture high-quality Anhydrous Magnesium Sulfate. Through controlled dehydration, purification, drying, and inspection procedures, the product achieves stable purity, uniform appearance, and reliable performance.
During production, professional quality inspection is carried out on key indicators including magnesium content, sulfur content, moisture level, impurity content, and powder characteristics. This ensures consistent product quality for bulk orders and long-term cooperation with global customers.
AOLANSU Anhydrous Magnesium Sulfate is widely used as a magnesium and sulfur fertilizer supplement for fruit trees, vegetables, field crops, and protected agriculture. It helps correct magnesium deficiency symptoms such as leaf yellowing, reduced photosynthetic activity, and weak plant growth.
For fruit crops including apples, citrus, grapes, and other high-value plants, the product supports chlorophyll formation, improves leaf vitality, promotes fruit development, and contributes to better appearance and quality. For vegetables and field crops such as tomatoes, peppers, corn, wheat, and peanuts, it provides essential nutrients throughout different growth stages.
With excellent water solubility and stable nutrient performance, AOLANSU Anhydrous Magnesium Sulfate is suitable for precision agricultural systems including fertigation, drip irrigation, and foliar spraying. It allows growers to apply magnesium and sulfur nutrients according to crop requirements, improving fertilizer management efficiency.
The product is especially suitable for greenhouse cultivation, intensive farming, and high-value crop production where accurate nutrient supply is important for maintaining stable crop quality.
Beyond agricultural use, Anhydrous Magnesium Sulfate is also used as an important magnesium compound raw material in industrial applications. It can be applied in chemical processing, pharmaceutical production, food-related industries, and other fields requiring stable magnesium sulfate materials.
AOLANSU provides customized specifications, packaging options, and supply solutions to meet different industrial application requirements.
An apple orchard in Penglai, Shandong applied AOLANSU Anhydrous Magnesium Sulfate during the fruit expansion and coloring period. The grower combined foliar spraying with drip irrigation supplementation to improve magnesium and sulfur nutrition.
After application, the orchard showed stronger leaf growth, improved leaf color, and better fruit uniformity. The apple sweetness increased by approximately 2–3 degrees (Brix), while the proportion of high-quality marketable fruit improved compared with previous cultivation results. The grower reported that the product provided stable nutrient supplementation and supported improved commercial fruit value.
A vegetable production base in Shandong used AOLANSU Anhydrous Magnesium Sulfate through fertigation and foliar application during the seedling and fruiting stages of chili peppers.
The treated area demonstrated stronger plant growth, greener leaves, and improved fruit development. At harvest, the peppers achieved better appearance and commercial quality, with yield performance higher than the conventional fertilization comparison area.
A: The main difference is crystal water content. Anhydrous Magnesium Sulfate does not contain crystal water, resulting in higher effective nutrient concentration and lower transportation weight compared with Magnesium Sulfate Heptahydrate. It is suitable for applications requiring concentrated magnesium and sulfur supplementation, precise dosing, and improved storage efficiency.
A: Yes. Agricultural-grade Anhydrous Magnesium Sulfate is an effective magnesium and sulfur fertilizer source. It can be applied through soil fertilization, fertigation, drip irrigation, and foliar spraying according to crop requirements and agricultural practices.
A: AOLANSU Anhydrous Magnesium Sulfate has good compatibility with many commonly used fertilizers, including water-soluble fertilizers and NPK fertilizers. However, compatibility testing is recommended before mixing with specific formulations, especially products containing strong alkaline components.
A: Because Anhydrous Magnesium Sulfate has strong hygroscopic characteristics, it should be stored in a dry, ventilated environment with moisture-proof packaging. After opening, the package should be resealed properly to prevent moisture absorption and product caking.
A: Yes. AOLANSU provides customized solutions including particle size, packaging specifications, bag printing, and branding options according to customer requirements. This service supports fertilizer distributors, agricultural companies, and industrial buyers worldwide.
AOLANSU specializes in the research, production, and supply of magnesium sulfate products and chemical raw materials.
