In 2020, the total production of magnesium sulfate in China and abroad will be about 5.5 million tons, with basically balanced supply and demand, of which 5 million tons will be used for fertilizer, accounting for 90% of the demand, and 500,000 tons will be used for other purposes, accounting for 10% of the demand.
Magnesium sulfate for fertilizer is the main use of magnesium sulfate, accounting for 90% of the demand.
With magnesium sulfate fertilizer, for example, according to the country's 1770 soil samples available magnesium content and soil nutrient status system study about magnesium on crop nutrition fertilizer recommendations, calculated at 125 million hectares of cultivated land in our country at present, the serious lack of magnesium of about 010 million hectares, soil to fill 2.8 million tons of MgO style, magnesium deficiency soil about 016 million hectares, to add 3.74 million tons of MgO style, medium soil of soil magnesium content about 041 million hectares, to fill 3.3 million tons of MgO style, a total of each year to add 9.84 million tons of MgO style in our country, is equivalent to 40 million tons of magnesium sulfate (25% MgO style),
It accounts for about a quarter of the fertilizer used in Asia, and the potential demand is huge.
As a source of raw materials of low and medium grade magnesite domestic reserves, another kind of raw materials, adequate supplies of sulfuric acid magnesium sulfate product cost is low, the introduction of production technology, energy saving, high efficiency, open flexible, less equipment investment, short construction period, so domestic production enterprises can keep the production capacity of more than demand, oversupply situation will exist for a long time.
