The application of magnesium nutrition and magnesium fertilizer has been a concern for the international agro-scientists and soil-fertilizers. Magnesium is one of the essential growth elements of crops and the core element of chlorophyll. Magnesium can promote the consolidation of loose soil, shorten the growth cycle, and significantly improve the brightness, color and taste of fruits. Agricultural magnesium sulfate contains both magnesium and sulfur plant nutrients, applicable to all plants and a variety of soil conditions. The raw materials used for the production of magnesium sulfate for agriculture by the chemical method are the “corner remnants†and low-grade magnesia in the production process of refractory materials, and belong to the magnesium deep processing project and the comprehensive utilization of resources. At present, there are widespread symptoms of magnesium deficiency in the world and agricultural production has a great potential for magnesium fertilizer demand.
Yingkou Magnesite Chemical (Group) Co., Ltd. has been engaged in the research, development and production of magnesium chemical industry for many years, and achieved technological breakthroughs in research and development. This time, the company drafted and formulated the “National Standard for Magnesium Sulfate for Agriculture†will play an important role in regulating the production and operation of enterprises, ensuring the quality of products, promoting international trade, increasing the yield of crops, and improving the quality of crops.
