Function of magnesium sulfate:
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.
1.Magnesium sulfate 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 sulfate used in the industrial
It can be used in printing and dyeing, Industry,monosodium glutamate and yeast fermentationand as accessory ingredient for ABS and PVC resin
