3. Magnesium is the activator of many enzymes, and participating in the formation of some enzymes can improve the activity of enzymes and promote the metabolism of crops.

4. Magnesium can improve the disease resistance of crops and reduce the possibility of disease.

5. Magnesium can promote the synthesis of vitamin A and vitamin C in crops, and sulfur is an essential raw material for crops to synthesize amino acids, protein, cellulose and other nutrients.
