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

Usage:
(1) magnesium sulfate contains two essential nutrients: sulphur and magnesium. Magnesium sulfate can not only increase the yield of crops, but also improve the taste of crops.
(2) because magnesium is the component of chlorophyll and pigment, the only metal element in chlorophyll molecules, magnesium promotes photosynthesis and promotes the formation of carbohydrates, proteins and fats.Magnesium is an activator of hundreds of enzymes and is involved in the formation of enzymes that promote the metabolism of crops.Magnesium can improve the disease resistance of crops and prevent the invasion of bacteria.
(3) magnesium can also promote the formation of vitamin A and vitamin C in crops, thus improving the quality of fruits, vegetables and other crops.Sulfur is essential for the synthesis of amino acids, proteins, cellulose and enzymes in crops.
(4) magnesium sulfate can also be used to promote the absorption of silicon and phosphorus
