Potassium Sulphate




Potassium sulphate is next to potassium chloride the most common potassium nutrient used in crop nutrition.
Potassium sulphate also called Potassium Sulfate /Sulphate of Potash(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 Sulphate of Potash (SOP) does not contain any chlorides, which can be harmful to some crops like tobacco, fruits and vegetable.
