Magnesium sulphate                                                                                              

Magnesium sulfate (or magnesium sulphate, Epsom salt ,Bitter salt ) is a chemical compound containing magnesium ,sulfur and oxygen,with the formula Mgso_4.  In its hydrated form ,the PH is 6.0(5.5-6.5).It is often encountered as the heptahydrate ,Mgso_4·7H₂O, commonly called Epsom salt. Anhydrous magnesium sulfate is used as a drying agent .Since the anhydrous form is hygroscopic (readily absorbs water from the air )and is therefore difficult to weigh accurately, the hydrate is often prefered when reparing solutions ,for example ,in medical preparations ,Epsom salt has been traditionally used as a component of bath salts .

In agriculture and gardening ,magnesium sulfate is used to correct magnesium derficiency in soil ,since magnesium is an essential element in the chlorophyll molecule. It is the commonly applied to potted plants ,or to magnesium-hungry crops ,such as potatoes ,roses ,tomatos ,peppers amd cannbis. The advantage of magnesium sulfate over other magnesium soil amendments (such as dolomitic line )is its high solubility.

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.

1.Magnesium sulphate for agriculture
Sulfur and magnesium can provide rich nutrients for crops that it contributes to crop growth and increase the output, it also helps to loosen the soil and improve soil quality.
The symptoms of lacking of "sulfur"and"magnesium":
1) It lead to exhaustion and death if it's serious lacked;
2) The leaves became smaller and its edge will became dry shrinkage.
3) Susceptible to bacterial infections in premature defoliation

2.Magnesium sulphate used in the industrial
It can be used in printing and dyeing, Industry,monosodium glutamate and yeast fermentation and as accessory ingredient for ABS and PVC resin

3.Magnesium sulphate for stock raising
Magnesium is usually Fertilization among the early spring and the end of the year, until the grass can provide adequate magnesium ,it can also added in the feed and drinking water to meet growing demand of dairy cow's sebum, in order to improve the quality and quantity of milk cows.

4.Magnesium sulphate which contains a small amount of crystal water or non-crystalline water can be used for organic synthesis and the desiccant and dehydration agent of feed and fertilizer.

1. In agriculture and gardening, Magnesium sulphate is used to correct magnesium deficiency in soil,since magnesium is an essential element in the chlorophyll molecule.It is most commonly applied to potted plants, or to magnesium-hungry crops,such as potatoes,roses,tomatoes and pepper.The advantage of Magnesium sulfate over other magnesium soil amendments(such as dolomitic lime) is its high solubility.

2. Magnesium sulphate is also used to maintain the magnesium concentration in marine aquaria which contain large amounts of stony corals as it is slowly depleted in their calcification process.In a magnesium-deficient marine aquarium is present to sabilize these ions in the saltwater and prevent their spontaneous precipitation ionto calcium carbonate.

3. Magnesium sulphate is used as the electrolyte to prepare copper sulfate.

4. Magnesium sulphate is used as a brewing salt in beer production to adjust the ion content of the brewing water and enhance enzyme action in the mash or promote a desired flavor profile in the beer.

5. Magnesium sulphate is also widely apply in medical use. 

The advantages of MgSO4                                                          

l Fully water-soluble

l Consists of 100% plant nutrients

l Efficient Mg and S nutrients for the light soil and acid soils, especially for the calcareous soils and soils with a high pH, which high calcium concentrations in the soil solution impede the magnesium availability.

l Granular fertilizer has excellent spreading properties due to the well-defined granulometry and the hardness of the granules. These qualities also make it equally well suited for bulk blending.
