Product Description

Factory price agricultural grade fertilizer potassium sulfate K2SO4

1) Description:

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 . Potassium sulphate contains between 50-52% of K2O and approx. 18% of s  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.
