The partial salt index of sulphate of potash is lower than muriate of potash (KCl). It does not produce any acidity or alkalinity in the soil. It is an excellent fertilizer and can be applied to all soils and all crops. On soils prone to salinity the use of SOP should be the preferred potash fertilize.
