Magnesium Sulfate is a fundamental agricultural input that delivers two essential nutrients—magnesium and sulfur—in highly soluble, plant-available forms. As a key component of chlorophyll and numerous enzymes, magnesium sulfate is indispensable for photosynthesis, protein synthesis, and overall crop health. Our high-purity magnesium sulfate fertilizers are engineered to correct deficiencies rapidly and improve crop performance across diverse growing systems.

Core Benefits of Magnesium Sulfate Fertilization

1. Chlorophyll Synthesis and Photosynthesis Efficiency
Magnesium is the central atom in chlorophyll molecules. Adequate magnesium nutrition ensures optimal photosynthesis, leading to:

• Enhanced energy production for growth and development
• Improved carbohydrate accumulation and yield potential
• Greater resistance to environmental stressors

2. Sulfur Supply for Protein and Enzyme Formation
Sulfur is a vital component of amino acids, vitamins, and enzymes. Magnesium sulfate provides sulfate-sulfur that supports:

• Protein synthesis and nitrogen use efficiency
• Oil production in oilseed crops
• Development of flavor compounds in vegetables and fruits

3. Correction of Nutrient Deficiencies
Magnesium sulfate effectively addresses both magnesium and sulfur deficiencies, which are increasingly common in intensive cropping systems. Symptoms corrected include:

• Interveinal chlorosis (yellowing between leaf veins)
• Stunted growth and reduced tillering
• Poor fruit set and development

4. Improved Crop Quality and Marketability
Balanced magnesium and sulfur nutrition enhances:

• Fruit size, color, and sugar content
• Grain protein levels in cereals
• Shelf life and post-harvest quality
• Overall crop market value

Application Methods and Recommendations

Soil Application

• Broadcast Incorporation: 50-200 kg/ha depending on soil test results and crop requirements
• Banding: 25-100 kg/ha placed near root zones for efficient uptake
• Best Practices: Apply before planting or during early growth stages; incorporate into soil to maximize availability

Foliar Spray

• Concentration: 1-2% solution (10-20 g/L water)
• Timing: Early morning or late afternoon applications to maximize absorption
• Frequency: 2-3 applications at 10-14 day intervals for severe deficiencies
• Compatibility: Mixes well with most pesticides and nutrients (conduct jar test first)

Fertigation and Hydroponics
