High-purity kieserite magnesium (natural magnesium sulfate monohydrate, MgSO4.H2O, CAS No. 14168-73-1) is an essential, mineral-derived plant nutrient and industrial raw material. Engineered specifically for broadacre agriculture, commercial fertilizer manufacturing, and soil remediation, our product delivers a concentrated supply of fully bioavailable magnesium (MgO≥27%) and elemental sulfur (S≥20%).
Unlike synthetic alternatives, our natural kieserite granular formulation provides a sustained-release nutrient profile that does not alter soil pH levels, making it the preferred choice for commercial growers, bulk blenders, and chemical distributors worldwide.
Chemical Composition: MgSO4.H2O (Natural Kieserite Mineral)
Active Nutrient Content: Total MgO≥27%, Water-Soluble MgO≥20.0%, Elemental S≥20%
Physical Form: Uniform, hard spherical kieserite granular (2.0 mm – 5.0 mm, ≥ 90% in range)
Granule Hardness: ≥25N per particle, offering high crushing strength to prevent crushing and dusting during transport
Solubility: Dissolves predictably in soil moisture to sustain root uptake throughout the crop growth cycle
Mechanical Broadacre Spreading & Plantation Crops:
Our kieserite granular product is specifically processed for smooth mechanical spreading across large agricultural operations. It supplies immediate and sustained kieserite magnesium to oil palm plantations, rubber trees, citrus orchards, corn, and potatoes, driving chlorophyll production and enhancing nitrogen uptake efficiency.
Bulk Dry NPK Blending:
With tight particle size control (2–5 mm), our granular product matches the physical properties of urea, DAP, and muriate of potash (MOP). This structural uniformity prevents particle segregation during mechanical mixing, bagging, and field application.
Soil Remediation in Acidic & Leached Environments:
In high-rainfall tropical regions prone to heavy nutrient leaching, kieserite magnesium restores essential cations without increasing soil alkalinity or disrupting calcium and potassium adsorption ratios.
Industrial Processing & Animal Feed Additives:
Selected grades serve as functional precursors in specialty chemical processing, wastewater treatment coagulation, and dense magnesium sources for livestock mineral blocks.
Maintaining structural granule integrity and preventing moisture degradation during long-haul ocean freight is central to our supply process:
Packaging Formats: Available in heavy-duty 25 kg / 50 kg PP woven bags with thick PE inner liners, as well as 1000 kg, 1200 kg, or 1250 kg jumbo super sacks fitted with bottom discharge spouts.
Global Shipping Terms: We regularly execute shipments under FOB, CFR, CIF, and DDP terms with quick dispatch from major container ports.
Quality & Compliance: Every lot is backed by a Certificate of Analysis (COA), Safety Data Sheet (SDS/MSDS), and complete origin documentation to ensure rapid customs clearance.
