Magnesium sulfate manufacturer, MgO fertilizer supplier, MgSO4 factory since 1993: Tianjin Xingyu Fertilizer Industry Co., Ltd.(abbreviated as XYF) is supplier and manufacturer of magnesium sulfate heptahydrate, magnesium sulfate anhydrous, magnesium sulfate monohydrate and kieserite. Our factory is located in Jinghai, Tianjin, China, and the geographic distance is only 80 kilometers from our factory to Tianjin port.
There are two main raw materials for kieserite: magnesium oxide and sulfuric acid. In our opinion, good raw material is one of the key points to ensure the products’ quality. So we have developed our own high-quality magnesium mine base in Liaoning Province, and use high-quality sulfuric acid as raw material.
The picture above shows the packing process, workers are loading the goods into the container. For kieserite, one container can hold 25 tons, and the maximum can hold 27.5 tons, for packaged in 50kg PP bags.
As one of the MgO fertilizer, magnesium sulphate granular kieserite can provides the plant with the magnesium nutrient essential for its growth and also provides sulfur. The kieserite granules can usually be used as a base fertilizer and used in conjunction with other fertilizers for better results.
