Natural kieserite fertilizer (magnesium sulfate monohydrate, MgSO4.H2O is a highly concentrated, mineral-derived soil amendment engineered for commercial agriculture, broadacre farming, and industrial fertilizer production. Processed from natural salt deposits under rigorous quality control standards, our premium kieserite powder supplies fully bioavailable, water-soluble magnesium MgO≥27% and sulfur S≥20% to promote healthy crop establishment, optimize chlorophyll synthesis, and maximize crop yields.
As an experienced wholesale exporter and bulk chemical supplier, we provide consistent particle sizing, low heavy-metal thresholds, and flexible ocean freight options designed to help commercial buyers and regional distributors streamline their raw material procurement.
Chemical Identifiers: MgSO4.H2O | CAS No. 14168-73-1 | Natural Mineral Origin
Active Nutrient Yield: Total MgO≥27%, Water-Soluble MgO≥20.0%, Elemental S≥20%
Physical Form: Fine, free-flowing off-white to light grey kieserite powder (60–100 mesh options).
Soil Compatibility: Neutral pH impact (5.0 - 8.0 in 10% aqueous solution) that replenishes vital nutrients without causing soil acidification or altering baseline alkalinity.
Broadacre Cash Crop & Plantation Nutrition:
Applying kieserite fertilizer delivers an immediate supply of readily available magnesium and sulfur essential for photosynthesis, enzyme activation, and protein synthesis. It is extensively utilized across palm oil plantations, citrus orchards, sugarcane fields, rubber estates, corn, and potato crops.
Targeted Remediation for Acidic & Leached Soils:
In tropical and high-rainfall agricultural zones, essential cations are frequently washed away. Finely milled kieserite powder penetrates the root zone efficiently to treat magnesium deficiencies without interfering with potassium or calcium uptake ratios.
Compound NPK Formulation & Fertigation Blends:
Serves as an indispensable raw material for secondary fertilizer manufacturers. It dissolves rapidly in water-soluble fertigation mixtures and acts as a high-density micronutrient source during dry chemical compounding.
Livestock Feed Additive & Industrial Uses:
Beyond soil management, feed-grade monohydrate formulations act as a magnesium supplement in animal feed blocks, while technical grades serve as coagulation agents in wastewater treatment.
Protecting fine kieserite powder against atmospheric moisture during extended sea transit is critical to maintaining product fluid dynamics:
Bulk Packaging Options: Supplied in heavy-duty 25 kg / 50 kg PP woven bags with thick PE moisture barriers, or 1000 kg / 1200 kg jumbo super sacks featuring bottom discharge spouts for automated hoppers.
Shipping Terms & Traceability: We support FOB, CFR, CIF, and DDP trade terms directly from primary container ports with complete batch traceability.
Full Compliance Documentation: Every shipment includes a Certificate of Analysis (COA), Safety Data Sheet (SDS/MSDS), and origin certification to ensure smooth customs clearance.
