It is most commonly applied to potted plants, or to magnesium-hungry crops, such as potatoes, roses, tomatoes, lemon trees, carrots, and peppers. It also used in printing and dyeing,monosodium glutamate and yeast fermentation and as accessory ingredient for ABS and PVC resin. Magnesium Sulphate Heptahydrate 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. Also can be used in stockfeed additive leather, dyeing, pigment, refractoriness, Ceramic, marchdynamite and Mg salt industry. Usage: Agriculture:�  Magnesium Fertilizer plays an important role on the growing of plants. Magnesium is the main component of chlorophyll, and activator of many enzyme. It can promote metabolism of carbohydrate, and promote the synthesis of nucleic acid and the conversion of phosphate. Feed Additive: Magnesium Sulphate act as a magnesium supplement in feed processing. If the livestock and poultry,s body is short of magnesium, it will disorder the metabolism and neutral function, cause the imbalance of the growth of livestock and poultry and even lead to death. Industry: It can be applied in paper industry, rayon and silk industry. It can be used for the thin cotton printing and dyeing, the silk weighting and the product packing if the ceibas. In the light industry, it can be used for the production if yeast, monosodium glutamate, and act as the stabilizer of Calcium Hydrogen in the toothpaste producing process. In the leather-making industry, it can be used ad filling agent to improve the heat resistance.
