AOLANSU Magnesium Sulfate Granular is a granular magnesium and sulfur fertilizer developed for agricultural distributors, commercial farms, orchards, and industrial users that require a clean, easy-to-handle source of magnesium and sulfur. With Mg≥16% and S≥13%, it provides two essential nutrients in one granular product, helping maintain soil nutrient balance and support healthy crop development.
Unlike conventional magnesium sulfate powder, the granular form is designed around practical handling requirements. Its 2-4mm particle size, low dust generation, good flowability, and fast water solubility make it easier to transport, store, spread, and integrate into modern fertilizer application systems. AOLANSU also provides customized particle sizes and packaging options for different markets and application equipment.
Manufactured by Shandong AOLANSU Environmental Protection Technology Co., Ltd., a professional China Magnesium Sulfate Granular manufacturer and supplier, the product is suitable for orchards, vegetable farms, greenhouse cultivation, field crops, fertigation, and selected industrial applications. Each production batch is controlled for nutrient content, particle size, moisture, appearance, and physical handling performance.
Magnesium is a key component of chlorophyll and plays an important role in photosynthesis, while sulfur is involved in protein and enzyme formation. When soil cannot supply sufficient magnesium or sulfur, crops may show symptoms such as leaf yellowing, reduced vigor, poor development, and lower crop quality.
AOLANSU Magnesium Sulfate Granular provides both nutrients in a convenient granular format. It can be incorporated into a fertilization program when soil testing or crop conditions indicate a requirement for additional magnesium and sulfur.
For orchard and high-value crop production, magnesium supplementation can be particularly important because long-term nutrient imbalance may affect leaf performance and fruit development. Combining magnesium and sulfur in one fertilizer source can simplify nutrient planning and reduce the need to handle multiple individual products.
For B2B fertilizer buyers, product performance is not limited to nutrient content. Granule quality can directly affect transportation, warehouse management, spreading efficiency, and compatibility with fertilizer machinery.
AOLANSU Magnesium Sulfate Granular is supplied in a regular 2-4mm particle size. The relatively uniform granules support more consistent distribution during fertilizer spreading and reduce the handling problems commonly associated with fine powder materials.
The granular structure provides good flowability, making the product suitable for fertilizer spreaders and other mechanical application equipment. This is particularly useful for commercial farms and distributors serving customers who rely on mechanized field operations.
Compared with magnesium sulfate powder, granular material generates less airborne dust during routine loading, transportation, and fertilizer application. This creates a cleaner working environment and makes bulk material handling more convenient.
The product is designed to dissolve efficiently in water, allowing it to be used in appropriate fertigation and drip irrigation programs. This provides additional flexibility for growers who combine granular fertilizer supply with irrigation-based nutrient management.
Uniform granules and moisture-resistant packaging make the product convenient for container transportation, warehouse storage, and international distribution. Standard 25kg and 50kg packaging is available, with customized solutions for different markets.
AOLANSU Magnesium Sulfate Granular can be incorporated into different crop nutrition programs according to soil conditions, crop requirements, and local agricultural practices. The appropriate application rate should be determined according to soil testing and professional agronomic recommendations.
When magnesium and sulfur supplementation is required before planting, Magnesium Sulfate can be incorporated into the soil as part of the base fertilizer program. This approach allows growers to address nutrient requirements during field preparation and establish a balanced nutrient environment for the crop.
For established crops, granular magnesium sulfate can be used as a supplementary fertilizer when additional magnesium or sulfur is required during the growing season. Its uniform particle structure supports convenient field application and mechanical spreading.
Fruit trees such as apples, citrus, and grapes may require additional magnesium and sulfur depending on soil conditions and crop nutrient status. AOLANSU Magnesium Sulfate can be incorporated into orchard fertilization programs to supplement these nutrients and support healthy leaf development and fruit production.
Greenhouse vegetables and high-value crops require careful nutrient management because intensive production can gradually change soil nutrient levels. Magnesium Sulfate Granular can be included in fertilization programs for crops such as tomatoes, peppers, cucumbers, and other vegetables when magnesium or sulfur supplementation is required.
Because of its water solubility, the product can be dissolved and applied through suitable fertigation or drip irrigation systems. Application concentration, filtration, compatibility, and irrigation management should be evaluated according to the specific system and local agricultural practices.
| Crop / Application | Why Magnesium and Sulfur Matter | Recommended Product Advantage |
|---|---|---|
| Apple Orchards | Supports leaf function and balanced crop nutrition | Suitable for orchard soil application and seasonal supplementation |
| Citrus | Supports chlorophyll formation and plant development | Can be incorporated into regular orchard fertilization programs |
| Grapes | Provides magnesium and sulfur during crop development | Uniform granules simplify field and vineyard application |
| Tomatoes and Peppers | Supports balanced nutrient management in intensive cultivation | Suitable for soil application and appropriate fertigation programs |

The choice between granular and powdered magnesium sulfate often depends on how the fertilizer will be transported and applied. Powder can be useful for certain industrial or agricultural processes, but it may create more dust and can be less convenient for mechanical field spreading.
AOLANSU Magnesium Sulfate Granular is designed specifically for buyers who prioritize handling efficiency. The 2-4mm particles provide better flowability and more convenient mechanical distribution while maintaining the water-soluble characteristics required for efficient nutrient availability.
| Feature | Magnesium Sulfate Granular | Magnesium Sulfate Powder |
|---|---|---|
| Particle Form | Uniform granules | Fine powder |
| Dust Generation | Lower | Higher during handling |
| Mechanical Spreading | Highly suitable | More equipment-dependent |
| Flowability | Good | More prone to handling issues |
| Transportation | Convenient for bulk distribution | Requires greater dust and moisture control |
| Water Solubility | Fast dissolving | Fast dissolving |
An apple orchard in Qixia, Shandong had experienced long-term magnesium and sulfur deficiency associated with its soil conditions. The orchard observed weak leaf growth, uneven fruit coloring, and a lower proportion of premium-grade apples, creating challenges for consistent commercial fruit production.
The grower incorporated AOLANSU Magnesium Sulfate into the orchard's fertilizer program as a base fertilizer and seasonal top dressing. The application was designed to supplement magnesium and sulfur according to the orchard's nutrient management requirements.
Following the application, the orchard reported improved leaf vitality, stronger photosynthetic performance, and more uniform fruit appearance. The percentage of apples larger than 80mm exceeded 90%, while measured sugar content increased by approximately 2-3 degrees compared with previous seasons.
The improvement in fruit size, appearance, and sugar content contributed to better market value and demonstrated how targeted magnesium-sulfur supplementation can form part of a broader orchard nutrition strategy.
