Photosynthes can't go on without it. It is the activating agent of many enzymes. 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. magnesium sulphate for agriculture magnesium and sulfur 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 "magnesium" and "sulfur": 1) it leads to exhaustion and death if it's serious lacked. 2) the leaves became smaller and its edge will become dry shrinkage. 3) susceptible to bacterial infections in premature defoliation.
