在星宇肥料（Xingyu Fertilizer）的产品体系中，在 ID 243（Kieserite Powder 粉末版）之后，ID 244 通常对应的是其大宗出口的另一核心规格——Kieserite Granular / Compacted Granular（一水硫酸镁颗粒 / 挤压颗粒硫镁肥）。

与粉末版本相比，颗粒版（Granular Grade）专为机械撒施、飞机喷撒以及与 NPK 大颗粒肥料干混（Bulk Blending）而设计，具有硬度高、无粉尘、流动性好、抗结块等特点。

Premium Kieserite Granular & Magnesium Sulphate Monohydrate Manufacturer

Tianjin Xingyu Fertilizer Co., Ltd. is a leading global manufacturer and exporter of premium Kieserite granular fertilizer, specializing in supplying robust agricultural chemical solutions to international markets. Backed by our modern 20,000 m² production facility and an annual manufacturing capacity exceeding 300,000 metric tons, we deliver high-density Magnesium Sulphate Monohydrate granules to global fertilizer importers, commercial plantation managers, and bulk blending (BB) plant operators worldwide.

Why Compacted Kieserite Granules excel in Modern Agriculture

Kieserite granular (MgSO4·H2O granules) represents an advanced physical form of magnesium sulphate monohydrate engineered for mechanized agricultural operations. Magnesium is the essential core atom of chlorophyll molecules, driving active photosynthesis, sugar transport, and crop enzyme activation. Sulfur is a fundamental building block for plant protein synthesis, nitrogen optimization, and foliage growth.

Unlike fine powders that drift in the wind or soluble salts that leach rapidly during heavy rain, compacted Kieserite granules offer a sustained release mechanism. Their uniform particle size ensures even nutrient distribution across the root zone, making them particularly effective for tropical climate plantations, high-rainfall zones, and coarse sandy soils.

Key Product Advantages & B2B Features

• High Hardness & Dust-Free: Advanced compacting technology creates hard, smooth granules (2-5mm) that resist crushing, minimalizing dust generation during handling and maritime transport.

• Optimal Bulk Blending Compatibility: Identical physical granule size matching with common NPK, DAP, and Urea particles, preventing segregation in bulk-blended (BB) commercial fertilizer mixes.

• Controlled Slow-Release Action: Delivers a continuous, long-lasting supply of magnesium and sulfur throughout the crop growing cycle without leaching risks.

• Strict Certified Quality Assurance: Fully compliant with ISO 9001 standards. Every export batch is tested for crushing strength and chemical purity, backed by a COA and supporting SGS, BV, or CCIC third-party inspections.
