The potassium sulphate or potassium sulphate is a chemical compound with the formula K2SO4which is presented as a white powder or in granular form. Potassium sulphate is mainly used as a fertiliser in crops. Potassium (K) is one of the main plant nutrients and potassium sulphate is the main form of potassium sulphate. Potassium sulphate is a loose, crystalline product that dissolves quickly in water without leaving a residue. It can be applied using any fertigation system. It is suitable for all types of crops at developmental stages with high potassium requirements and low nitrogen needs.
