Magnesium Sulfate Monohydrate 99% – Concentrated Magnesium Source for Feed, Fertilizer & Industry
We supply high-purity Magnesium Sulfate Monohydrate with a 99% assay. This concentrated, free-flowing salt provides a potent and highly soluble source of bioavailable magnesium and sulfur. Consequently, manufacturers actively use it to fortify animal feed, correct soil deficiencies in agriculture, and serve as a reagent in industrial processes. Moreover, its low moisture content and high nutrient density make it an efficient and stable raw material.
Core Applications for Magnesium Sulfate Monohydrate in Key Sectors
This concentrated compound delivers essential nutrients and chemical functionality to agriculture and industry. Its roles are targeted and highly effective.
First, the animal nutrition industry relies on magnesium sulfate monohydrate 99% as a premium feed-grade mineral supplement. It is essential for metabolic functions, bone development, and enzyme activation in livestock, poultry, and aquaculture. Therefore, feed millers and premix manufacturers depend on it for producing nutritionally complete and balanced feeds.
Second, the agricultural sector utilizes it as a high-analysis water-soluble fertilizer. It rapidly corrects magnesium and sulfur deficiencies in high-value crops through soil application or foliar spraying. Furthermore, its high solubility makes it ideal for fertigation systems and hydroponic nutrient solutions.
Third, various industrial processes employ it as a chemical feedstock and processing aid. It is used in the production of other magnesium compounds, in textile and leather processing, and in the fermentation industry. Additionally, it finds application in specialty chemicals, bath salts, and as a coagulation agent.
