Potassium sulfate, chemical formula K ₂ SO ₄, is an inorganic salt, generally containing 50%~52% K and about 18% S. The pure potassium sulfate is a colorless crystal, and the appearance of agricultural potassium sulfate is mostly light yellow. Potassium sulfate is a good water-soluble potash fertilizer with low hygroscopicity, no caking, good physical properties and convenient application. Potassium sulfate is especially suitable for cash crops that hate chlorine and potassium, such as tobacco, grapes, sugar beets, tea trees, potatoes, flax and various fruit trees. It is also the main raw material for producing chlorine free nitrogen, phosphorus and potassium ternary compound fertilizer. Potassium sulfate is a chemically neutral and physiological acid fertilizer, which is suitable for a variety of soils (excluding flooded soils) and crops. After being applied to the soil, potassium ions can be directly absorbed by crops, and can also be absorbed by soil colloids.
