What is Magnesium Sulphate Monohydrate?
Magnesium Sulphate Monohydrate (MgSO4.H2O), also known by its mineral name Kieserite, is a more concentrated form of magnesium sulphate compared to the more commonly known heptahydrate (Epsom Salt), containing only one water molecule per formula unit instead of seven. This gives it a significantly higher magnesium and sulphur content per kilogram, making it a more concentrated and often more cost-effective nutrient source for large-scale fertiliser applications, while also offering better physical stability and reduced caking tendency compared to the heptahydrate form.
Polychem Industries supplies Magnesium Sulphate Monohydrate to fertiliser manufacturers, compound fertiliser blenders, and industrial chemical companies across India and internationally. Its higher nutrient concentration per kg compared to the heptahydrate form makes it particularly attractive for bulk fertiliser blending and large-scale agricultural applications where transport and storage efficiency matter.

Applications & Uses
Fertiliser Manufacturing & Blending
The primary application. Magnesium Sulphate Monohydrate is widely used as a magnesium and sulphur source in compound fertiliser manufacturing and blending operations, valued for its higher nutrient concentration and good physical handling properties compared to higher-hydrate forms.
Soil Application for Magnesium Deficiency
Applied directly to soil to correct magnesium deficiency in crops, providing both magnesium (essential for chlorophyll synthesis) and sulphur (required for protein synthesis) in a concentrated, granular form suited to broadcast application.
Textile Processing
Used in certain textile processing and dyeing applications, taking advantage of its specific chemical properties in textile finishing and dye-fixing processes.
Paper Manufacturing
Used in certain paper manufacturing processes as a functional additive, contributing to specific paper quality and processing characteristics required in the papermaking process.
Industrial Chemical Formulations
Used as a raw material in various industrial chemical formulations requiring a concentrated magnesium and sulphate source with good handling and storage stability.
Animal Feed Supplementation
Used as a magnesium supplement in animal feed formulations, providing a concentrated source of this essential mineral for livestock nutrition, particularly valuable for preventing grass tetany in grazing cattle.
