AOLANSU Magnesium Sulfate Heptahydrate is widely used as a magnesium and sulfur fertilizer supplement for fruit trees, vegetables, field crops, and greenhouse cultivation. It helps address magnesium and sulfur deficiencies that may affect plant growth, leaf color, photosynthetic activity, and crop development.
For fruit crops such as apples, citrus, grapes, and bananas, Magnesium Sulfate Heptahydrate supports healthy leaf growth and fruit development. For vegetables including tomatoes, peppers, lettuce, and leafy greens, it provides essential nutrients during key growth stages. For field crops such as rice, wheat, corn, and soybeans, it helps maintain balanced nutrient supply and improve crop performance.
Because of its excellent solubility, AOLANSU Magnesium Sulfate Heptahydrate is an important raw material for water-soluble fertilizer production. It can be formulated with other nutrients and applied through fertigation, drip irrigation, and foliar spraying systems.
This makes the product suitable for modern agricultural practices that require accurate nutrient management, efficient fertilizer utilization, and flexible application methods.
Beyond agricultural fertilizer applications, high-purity Magnesium Sulfate Heptahydrate is also used in industrial processing, textile and dyeing industries, chemical manufacturing, pharmaceutical-related applications, and food processing fields.
AOLANSU provides stable-quality magnesium sulfate raw materials with customized specifications and packaging options to meet different industrial requirements.
A rice production base in Southeast Asia experienced magnesium and sulfur nutrient deficiencies, resulting in weak stems, reduced leaf vitality, and uneven grain development. The farm introduced AOLANSU Magnesium Sulfate Heptahydrate through fertigation and foliar application during the tillering and grain-filling stages.
After application, the rice plants showed greener leaves, stronger growth, and improved nutrient balance. Field observation showed reduced lodging risk and better grain filling performance compared with previous cultivation practices. The growers reported improved crop uniformity and enhanced overall production efficiency.
A: Magnesium Sulfate Heptahydrate is suitable for a wide range of crops, including fruit trees, vegetables, field crops, and greenhouse plants. It is commonly used for magnesium-sensitive crops such as citrus, apples, grapes, tomatoes, peppers, rice, wheat, and corn.
A: Yes. Due to its excellent water solubility, Magnesium Sulfate Heptahydrate can be dissolved and applied through fertigation, drip irrigation, and foliar spraying systems. The application method and dosage should be adjusted according to crop type, growth stage, and soil conditions.
A: AOLANSU Magnesium Sulfate Heptahydrate has good compatibility with many commonly used fertilizers, including NPK fertilizers and water-soluble fertilizer products. Before mixing with specific formulations, compatibility testing is recommended, especially for products containing strong alkaline components.
A: The main difference is crystal water content. Magnesium Sulfate Heptahydrate contains seven water molecules in its crystal structure, providing excellent dissolution performance and wide application flexibility. Anhydrous Magnesium Sulfate contains no crystal water and offers higher nutrient concentration per unit weight, making it suitable for applications requiring concentrated magnesium and sulfur supply.
A: AOLANSU provides flexible packaging solutions including standard bags, customized printing, private labeling, and different specifications according to customer requirements. These services are available for fertilizer distributors, industrial buyers, and international partners.
