Description

Large Granular Magnesium Sulfate Heptahydrate Inorganic Chemicals – High-Purity, Agricultural Grade


Large Granular Magnesium Sulfate Heptahydrate (MgSO₄·7H₂O) is a high-purity, white crystalline compound with well-defined large particle size, typically ranging from 4 mm to 6 mm. It is manufactured in accordance with international standards such as USP, BP, EP, and CP, and is specially formulated for use in agriculture, horticulture, and certain industrial applications where low dust, controlled release, and excellent handling characteristics are required.

This product is composed of magnesium sulfate combined with seven molecules of water, providing both magnesium (Mg) and sulfur (S), two essential secondary nutrients for plant growth. Magnesium is vital for chlorophyll synthesis and enzyme activation, while sulfur is necessary for amino acid formation and metabolic function.

The large granular form is particularly advantageous in large-scale field applications. It reduces product loss due to wind drift, allows for even broadcasting via mechanical spreaders, and extends the release time of nutrients in soil. It is widely applied to crops such as vegetables, fruit trees, oilseed plants, tobacco, and grains.

In addition to its role in agriculture, large granular magnesium sulfate heptahydrate is also used in the production of magnesium-based chemicals, in wastewater treatment, and as a processing agent in industrial manufacturing.

This product is characterized by high solubility, purity of ≥99.5%, low impurity levels, and a neutral pH range suitable for most soil types. It is compatible with most NPK fertilizers and can be applied directly or as part of compound blends.
