Application
Magnesium is important element in chlorophyll, is necessary for photosynthesis. Magnesium is activator for many enzymes, is able to accelerate metabolism for carbohydrate, composition for nucleic acid, transform for phosphate, etc. Magnesium sulfate is very important fertilizer for its rich nutrition. Moreover, Magnesium benefits for crop growth and high yield. Magnesium sulfate not only provides Magnesium and Sulfate element, but also loosens soil. Magnesium and other 15 elements are considered as nutrition for plant growth and high yield, as well as nutrient component and fertilizer for relative plants. Traditional fertilizer contain such nutrient content as N, P, K, which can not enhance crop yield obviously, while, medium nutrient content (Ca, Mg, S) and minim nutrient ingredients (Zn, Cu, Fe, Mn, B, Mo and Cl) become less and less. It will cause low yield of crops. It is tested that the main reason is too much exploit of Magnesium from the soil. Magnesium is important ingredient for enhancing productivity and agriculture yield. So it needs compensated in time.
