    Potassium Sulphate

    Potassium sulfate is an inorganic salt with the chemical formula of K Ψ so ₄. Generally, the content of K is 50% – 52%, and the content of S is about 18%. The pure potassium sulfate is colorless crystal, and the appearance of agricultural potassium sulfate is mostly light yellow. Potassium sulfate is a good water-soluble potassium fertilizer because of its low hygroscopicity, low caking, good physical properties and convenient application. Potassium sulphate is especially suitable for the economic crops, such as tobacco, grape, sugar beet, tea plant, potato, flax and various fruit trees. It is also the main raw material for the production of chlorine free nitrogen, phosphorus, potassium ternary compound fertilizer. Potassium sulfate is a chemical neutral, physiological acid fertilizer, which is suitable for a variety of soil (excluding flooded soil) and crops. After being applied to soil, potassium ion can be directly absorbed by crops or absorbed by soil colloids. The results showed that potassium sulfate could be applied to Cruciferae crops and other crops which need more sulfur in the soil with sulfur deficiency.
