Magnesium sulfate is an inorganic salt (chemical compound) containing magnesium, sulfur and oxygen, with the formula MgSO4. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO4·7H2O), commonly called Epsom salt, taking its name from a bitter saline spring in Epsom in Surrey, England, where the salt was produced from the springs that arise where the porous chalk of the North Downs meets non-porous London clay. The monohydrate, MgSO4·H2O is found as the mineral kieserite.

Magnesium is the center element of chlorophyll, photosynthes can’t go on without it. It is the activating agent of many enzymes, such as it can promote the metabolism of carohydrates, nucleic acid synthesis, the conversion of phosphate, etc.It involves in the synthesis of proteins as an element of multi-core proteins, it’s the transmission medium of genes as part of the composition of genes.

In agriculture, magnesium sulfate is used to increase magnesium or sulfur content in soil. It is most commonly applied to potted plants, or to magnesium-hungry crops, such as potatoes, roses, tomatoes, lemon trees, carrots, and peppers. The advantage of magnesium sulfate over other magnesium soil amendments (such as dolomitic lime) is its high solubility, which also allows the option of foliar feeding. Solutions of magnesium sulfate are also nearly neutral, compared with alkaline salts of magnesium as found in limestone; therefore, the use of magnesium sulfate as a magnesium source for soil does not significantly change the soil pH.

1. In industrial,it used in printing and dyeing,monosodium glutamate and yeast fermentation and as accessory ingredient for ABS and PVC resin.

2.In gardening and other agriculture, magnesium is an essential element in the chlorophyll molecule, and sulfur is another important micronutrient.It is most commonly applied to potted plants, or to magnesium-hungry crops, such as potatoes, roses, tomatoes, lemon trees, carrots, and peppers.

3.Magnesium is one of the important compositions of animal skeleton and teeth. It helps activate many kinds of enzymes in organism, controls nerve muscle’s conduction, guarantees cardiac muscles’s normal contraction, and plays an influential role to the poultry vivo material metabolism.
