AOLANSU Anhydrous Magnesium Sulfate is a high-purity magnesium and sulfur compound developed for fertilizer manufacturers, agricultural input distributors, chemical processors, and industrial users requiring a concentrated and reliable magnesium source. With an anhydrous MgSO₄ composition and purity of ≥98%, it provides a high concentration of active material while offering excellent water solubility and consistent chemical performance.
Unlike hydrated magnesium sulfate products that contain crystal water, this material is processed through controlled dehydration and purification to remove bound water from the crystal structure. The resulting product provides a higher effective nutrient concentration per unit weight, which can be valuable for formulation manufacturers and buyers managing transportation, storage, and dosing efficiency.
Manufactured by Shandong AOLANSU Environmental Protection Technology Co., Ltd., a professional China magnesium sulfate manufacturer and supplier, the product is available for agricultural and industrial applications. AOLANSU also holds a Hazardous Chemicals Business License, providing qualified chemical business operation capabilities and additional confidence for international B2B customers evaluating a long-term chemical supply partner.
For fertilizer formulators and industrial buyers, the water content of a raw material can directly affect formulation concentration, transportation efficiency, storage requirements, and production calculations. Anhydrous magnesium sulfate contains no crystal water, allowing buyers to obtain more active MgSO₄ from the same shipment weight compared with hydrated grades.
This characteristic makes it particularly useful where concentrated nutrient formulations, accurate dosing, or reduced transportation of inactive crystal water are important purchasing considerations.
With a purity of ≥98%, the product provides a concentrated source of magnesium sulfate. This allows fertilizer manufacturers to formulate magnesium-containing products with greater flexibility while maintaining accurate nutrient calculations.
The anhydrous form does not contain the crystal water associated with magnesium sulfate hydrates. This results in a higher proportion of active MgSO₄ per unit of product weight and can improve transportation efficiency when comparing equivalent active-material requirements.
Its excellent water solubility allows the material to dissolve efficiently in appropriate agricultural and industrial formulations. This makes it suitable for water-soluble fertilizer production, fertigation systems, and other applications requiring rapid preparation.
AOLANSU controls key production parameters including purity, magnesium content, sulfur content, moisture, and appearance to maintain consistent characteristics between batches. Stable raw material quality helps downstream manufacturers reduce formulation variation.
Beyond fertilizer applications, the material can be used as a magnesium sulfate source in selected chemical, pharmaceutical, food-related, and industrial processing applications where the required grade and specifications are appropriate.

The production of high-purity magnesium sulfate requires effective control of dehydration and purification. AOLANSU uses a standardized processing route designed to reduce residual moisture while maintaining the required chemical composition and physical characteristics.
Selected magnesium sulfate raw materials are prepared according to the target product specification. Initial inspection helps control impurities and establish consistent input conditions before further processing.
The material undergoes controlled dehydration to remove crystal water and produce the desired anhydrous form. Process conditions are managed to maintain product quality while achieving the required moisture and purity specifications.
Additional processing is used where necessary to improve product consistency and control impurities. The finished material is processed into a fine crystalline powder suitable for downstream formulation and industrial use.
Before shipment, batches are evaluated for purity, magnesium content, sulfur content, moisture, appearance, and other agreed specifications. This quality management process helps international buyers maintain consistent production performance.
One of the main advantages of a concentrated magnesium sulfate raw material is its flexibility in fertilizer formulation. Rather than being limited to one crop-specific application, the material can be incorporated into different fertilizer products according to the required nutrient ratio and production process.
The excellent solubility of AOLANSU Anhydrous Magnesium Sulfate makes it suitable for selected water-soluble fertilizer formulations. It can provide magnesium and sulfur in formulations designed for intensive agriculture, greenhouse production, and other controlled nutrient-management systems.
For agricultural systems that deliver nutrients through irrigation water, a soluble magnesium source allows growers to manage nutrient input according to crop requirements. The product can be incorporated into suitable fertigation programs after compatibility and application-rate evaluation.
Fertilizer manufacturers can use concentrated magnesium sulfate as a raw material when developing specialty nutrient products for crops with specific magnesium or sulfur requirements. Its consistent composition supports more predictable formulation calculations.
Magnesium is associated with chlorophyll formation and photosynthetic activity, while sulfur contributes to protein and enzyme-related functions in plants. Where soil or crop analysis identifies magnesium or sulfur deficiency, an appropriate magnesium sulfate fertilizer program can help restore nutrient availability.
In addition to agricultural formulations, the material can function as a magnesium sulfate raw material for selected industrial processes. Its high purity and consistent chemical composition make it suitable for buyers who require a dependable source of MgSO₄ rather than a finished granular fertilizer.
Magnesium sulfate can be used as a magnesium-containing raw material in selected chemical production and processing applications. Product grade and purity requirements should be confirmed according to the specific process.
Magnesium sulfate is used in certain pharmaceutical-related applications. For such applications, customers should specify the required regulatory and quality grade before purchasing, as agricultural and pharmaceutical specifications are not interchangeable.
Magnesium sulfate may be used in selected food-related applications where permitted by applicable regulations and where the supplied grade meets the required food-grade specifications. Buyers should confirm the intended use and applicable regulatory requirements before ordering.
The product can also be considered for industrial formulations requiring a soluble magnesium sulfate source. AOLANSU can discuss purity, particle size, packaging, and other technical requirements with industrial buyers before quotation.
An apple orchard in Penglai, Shandong experienced magnesium-related nutrient imbalance during the fruit expansion and coloring stages. The grower incorporated AOLANSU magnesium sulfate into its nutrient management program through foliar spraying and drip irrigation supplementation.
Following application, the orchard reported stronger leaf development, improved leaf color, and more uniform fruit growth. Measured apple sweetness increased by approximately 2-3 degrees Brix, while the proportion of commercially desirable fruit also improved compared with previous cultivation results.
The case demonstrates how a soluble magnesium and sulfur source can be integrated into a crop-specific nutrient management program when additional magnesium supplementation is required.
A commercial vegetable production base in Shandong incorporated AOLANSU magnesium sulfate into its fertigation and foliar nutrition program for chili peppers during the seedling and fruiting stages.
The treated area showed stronger plant growth, greener foliage, and improved fruit development during the cultivation period. At harvest, the grower reported improved fruit appearance and commercial quality compared with the conventional fertilization comparison area.
When purchasing magnesium sulfate, buyers often compare the anhydrous and hydrated forms according to active content, transportation requirements, storage conditions, and final application. The choice should depend on the intended use rather than simply the purchase price per tonne.
