Description of Potassium Sulphate

Potassium sulphate is an important chlorine-free potassium fertilizer containing sulfur and potassium. K2O content is 50%-52%, and the S content is about 17%-18%. Agricultural potassium sulfate is mostly pale yellow. Potassium sulfate is a water-soluble potassium fertilizer because of its low moisture absorption, non-caking, good physical properties and convenient application. Potassium sulfate is especially suitable for cash crops that are resistant to chlorine and like potassium, such as tobacco, grapes, beet, tea, potatoes, flax and various fruit trees. It is also the main raw material for making chlorine-free nitrogen, phosphorus and potassium ternary compound fertilizer. Potassium sulfate is a chemical neutral and physiological acidic fertilizer, which is suitable for a variety of soils (excluding flooded soils) and crops. 

Potassium sulphate (SOP) is a water soluble, white and crystalline salt. The mineral form arcanite is relatively rare. The main resources for SOP are found in combination with other mineral sulfates, such as magnesium, sodium and calcium. Another way of producing SOP is a combination of potassium chloride and kieserite. Most common forms of manufacture are from potassium chloride through a synthetic reaction with sulfuric acid or sulfur dioxide. Potassium sulphate contains between 50-52% of K2O and approx. 18% of sulphur which is a needed element in plant growth and deficiant in many soils. Otherwise than potasssium chloride (SOP) does not contain any chlorides, which can be harmful to some crops like tobacco, fruits and vegetable.
