Magnesium is the necessary nutrient elements in the process of growing plant.It is the center element of chlorophyll,photosynthes can not go on without it.
It is the activating agent of many enzymes,and has a big effect for carbon metabolism,nitrogen metabolism,fat and active oxide action of the plant.
The magnesium Sulphate Fertilizer is perfect for the acid soil,highly leaching soil,boggy soil and sandy soil.
Magnesium Sulphate can be used in the plant of rice、wheat、cotton、corn、peanut、beans、flue-cured tobacco、sugarcane、tomato、beet、cole、potato、vegetable and other plant.Magnesium Sulphate can strengthen the photosynthesis,promote the growth of root,increase the yield and also loosen the soil and improve the soild quality for plant.
Magnesium Sulphate can be used as foliar-fertilizer and nutrient solution for soilless culture.
