Moisture-Resistant Potassium Sulfate Blend is a white crystalline powder, an inorganic salt with the chemical formula K2SO4. Agricultural potassium sulfate typically has a light yellow appearance and exhibits low hygroscopicity, preventing agglomeration and ensuring good physical properties. It serves as an excellent water-soluble potassium fertilizer, commonly utilized as a primary ingredient in chlorine-free nitrogen, phosphorus, and potassium compound fertilizers. This versatile compound can be directly applied as fertilizer to various soils and crops, enhancing their growth and yield. Additionally, it finds application as a food additive, providing dough conditioning properties, among other uses.
