⁣High quality potassium fertilizer raw material potassium sulfate

Potassium sulfate is a high content and quick acting potassium fertilizer, mainly prepared from sulfate ore anhydrous potassium magnesium aluminate and potassium chloride as raw materials. It is a white or light yellow crystalline particle with two crystal forms, α - and β -. The α - type is a colorless crystal in the hexagonal crystal system, while the β - type is a colorless crystal in the orthorhombic crystal system. It has a bitter and salty taste.

Generally, it contains 90% to 95% potassium sulfate, 50% to 52% potassium (K2O), 16% sulfur (S), and less than 2.2% chlorine (Cl); In addition, there are small amounts of sodium (Na), calcium (Ca), magnesium (Mg), bromine (Br), etc., which are insoluble in ethanol, acetone, and carbon disulfide, but easily soluble in water and can be directly absorbed and utilized by plants. They can be used as base fertilizer, seed fertilizer, and topdressing. Experimental results have shown that the application of 1 kilogram of potassium sulfate can increase the yield of grain crops by 6-8 kilograms and sugar beets by 15.5-22.5 kilograms. Some chlorine sensitive crops (such as fruits, flax, tobacco, tea, citrus, potatoes, etc.) cannot be treated with potassium chloride, but can be treated with potassium sulfate.
