High-Purity Kieserite Micro-Granular Fertilizer Manufacturer & Wholesale Supplier

Tianjin Xingyu Fertilizer Co., Ltd. is a premier manufacturer and exporter of specialized Kieserite micro-granular fertilizer, serving high-precision agricultural distribution networks around the globe. Operating from our advanced 20,000 m² chemical production hub with an annual manufacturing output reaching 300,000 metric tons, we supply high-uniformity Magnesium Sulphate Monohydrate micro-granules engineered specifically for modern precision agriculture, mechanized seeding, and specialized compound fertilizer formulations.

The Strategic Advantage of Kieserite Micro-Granules in Crop Nutrition

Kieserite micro-granular (MgSO4·H2O micro-granules) combines the excellent physical handling of uniform round particles with the long-lasting nutritional profile of slow-release magnesium and sulfur. Magnesium acts as the foundational central atom in chlorophyll molecules, fueling active photosynthesis, enzyme regulation, and sugar movement. Sulfur functions as a mandatory element for plant amino acid formation, protein synthesis, and foliage health.

The unique micro-spherical structure ensures significantly higher particle counts per square meter compared to standard large granules. This provides closer proximity to young crop root systems, accelerating early-stage magnesium absorption while offering a controlled, steady release rate that prevents nutrient leaching in high-rainfall tropical soils and sandy farmland.

Key Product Features & B2B Strengths

• Exceptional Particle Uniformity: Precision-milled micro-round shape (typically 1.0mm - 2.5mm) guarantees fluid flowability, zero bridging in mechanical seeders, and ultra-even soil distribution.

• Dust-Free & High Anti-Caking: Smooth spherical surface drastically cuts down operational friction dust, remaining free-flowing during long-distance oceanic transport and humid storage conditions.

• Superior Precision Blending: Blends seamlessly into specialty NPK formulations, turf fertilizers, and micro-nutrient starter fertilizers without risk of density segregation.

• ISO-Certified Quality Assurance: Produced strictly in accordance with ISO 9001 protocols. Each shipment comes complete with an official Certificate of Analysis (COA) and supports third-party verification by SGS, BV, or CCIC.
