Information

Agricultural-grade Magnesium Sulfate Fertilizer is a widely used medium-element fertilizer in modern agriculture. With magnesium (Mg) and sulfur (S) as its core nutrients, it encompasses various forms including Magnesium Sulfate Heptahydrate (MgSO₄・7H₂O), magnesium sulfate monohydrate (MgSO₄・H₂O), and Anhydrous Magnesium Sulfate (MgSO₄), making it suitable for field planting, greenhouse agriculture, and fruit and vegetable cultivation. It boasts excellent water solubility, high nutrient utilization, and strong soil compatibility, rapidly replenishing essential nutrients for crops and improving soil structure, making it a key fertilizer for enhancing crop yield and quality.

Core Nutritional and Physicochemical Advantages

·Comprehensive Nutrition: Magnesium is a core component of chlorophyll, directly participating in photosynthesis; sulfur is an important component of proteins and enzymes, enhancing crop resistance (drought resistance, cold resistance, and disease and pest resistance). The synergistic effect of these two elements provides dual support for crop growth through both "nutrient supply" and "stress protection."

• Excellent water solubility: The industrial-grade standard product has a solubility of over 26g/100mL at 20℃ (heptahydrate type). The monohydrate and anhydrous types dissolve even faster, allowing for rapid preparation of water-fertilizer solutions. It is suitable for various application methods such as drip irrigation, sprinkler irrigation, and fertigation, with no risk of equipment clogging.

• Soil-friendly: The pH is neutral (5% aqueous solution pH 5.0-9.0). It does not disrupt the soil's acid-base balance after application, and can neutralize acidic soils, improve soil aeration, promote microbial activity, and alleviate soil compaction with long-term use.

• High safety: Heavy metal (lead, arsenic, cadmium, etc.) content ≤0.001%, chloride ion ≤0.03%, no residue, no phytotoxicity, meeting the requirements of green agricultural production and ensuring the quality and safety of agricultural products.

    Four Core Benefits

· Promotes Growth and Prevents Yellowing: Quickly replenishes magnesium, resolving issues such as interveinal chlorosis, yellowing, and premature aging in crops caused by magnesium deficiency. This results in lush, green leaves and a 20-30% increase in photosynthetic efficiency.

· Improves Quality and Yield: Promotes the accumulation of nutrients such as sugars, vitamins, and amino acids, leading to uniform fruit enlargement, bright color, and increased sweetness (1-2 degrees Brix for melons and fruits). It also increases the thousand-grain weight of grain crops by 5-10% and yield per acre by 10-15%.

· Enhances Stress Resistance: Sulfur participates in crop protein synthesis, while magnesium promotes nutrient absorption and conversion, synergistically enhancing crops' resistance to drought, cold, and pests, reducing pesticide use.

· Improves Soil: Regulates soil pH, improves the structure of acidic soils, increases soil aeration and water retention, and enhances soil fertility, creating a favorable environment for crop root growth.

Application Precautions

· Avoid mixing with alkaline fertilizers (lime, wood ash) and phosphate fertilizers to prevent the formation of insoluble precipitates and reduced fertilizer efficiency (apply every 5-7 days);

· The concentration for foliar spraying should not be too high (not exceeding 2%). A small-scale test spray is recommended before the first application to observe the crop's response;

· Strictly follow the recommended dosage. Excessive application may lead to soil salt accumulation, affecting crop growth;

· Store in a dry, well-ventilated place. Seal the packaging to prevent moisture absorption and clumping. If clumping occurs, crush the contents; the fertilizer can still be used without affecting its efficiency.

Core Advantages of Procurement

· Controllable Costs: Direct supply from the manufacturer, eliminating intermediaries; bulk purchases (≥10 tons) receive preferential pricing; usage is reduced by 30% compared to ordinary Magnesium fertilizer for equivalent fertilizer effectiveness, lowering planting costs.

· Strong Product Competitiveness: Meets national agricultural standards, quality is traceable, easily gaining growers' trust, suitable for agricultural input suppliers to expand their market.

· Customized Services: Available in different forms (crystalline/powder/granules), packaging specifications (1kg/5kg/25kg/50kg/ton bag), supporting OEM/ODM production to meet brand operation needs.

· Export Adaptability: Supports customization according to importing country standards, providing complete customs declaration documents (HS code 28332100), suitable for foreign trade export business. • Quality Commitment: A Certificate of Assessment (COA) is provided for each batch of products;

• Logistics Support: Multimodal transport including road, rail, and sea freight is supported. Moisture-proof packaging (inner PE film + outer woven bag) ensures undamaged and moisture-free transportation;

• After-sales Response: 24-hour online consultation to promptly answer application questions, help solve practical problems for growers, and increase customer repurchase rate.
