Due to the production method of industrial magnesium sulfate, the main producers of magnesium sulfate must be distributed around the magnesium mine, with the most numerous in China's Liaoning Haicheng, Yingkou and Shandong Laizhou. Our magnesium sulphate factory is located in Liaoning, with annual output 200000.0mts.  In agriculture and horticulture, magnesium sulphate is used to properly deplete magnesium (magnesium is an essential element of chlorophyll molecules). This is the most common used for potted plants, or magnesium hungry crops such as potatoes, roses, tomatoes, peppers and marijuana. The advantage of applying magnesium sulfate over other magnesium sulfate magnesium soil improvers (such as dolomitic lime) is its high solubility.
