AOLANSU also provides customized particle sizes and packaging options for different markets and application equipment.

Magnesium Sulfate Granular fertilizer Granular Magnesium Sulfate production Magnesium Sulfate Fertilizer application

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.

What Does Magnesium Sulfate Granular Do for Crops?

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.

Designed Around Modern Fertilizer Handling

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.

1. Consistent 2-4mm Granules

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.

2. Better Flow Through Fertilizer Equipment

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.

3. Lower Dust During Handling

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.

4. Fast Water Solubility

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.

5. Easier Long-Distance Transportation

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.

Magnesium Sulfate for Different Fertilization Programs

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.

1. Base Fertilizer for Soil Preparation

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.

2. Top Dressing During Crop Growth

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.

3. Orchard Fertilization

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.

4. Greenhouse and Vegetable 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.

5. Fertigation and Drip Irrigation

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.

Application Across Different Crop Types

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
Corn and Wheat Provides supplementary magnesium and sulfur when required Compatible with mechanized fertilizer spreading
Peanuts and Oil Crops Supports crop nutrition where sulfur and magnesium are required Easy to handle in large-scale agricultural operations

Why Granular Magnesium Sulfate Is Different from Powder

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

Field Case: Magnesium-Sulfur Management in an Apple Orchard

1. Apple Orchard Application in Qixia, Shandong, China

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.
