Laboratory soil columns were utilized for comparison of four K sources—Sul-Po-Mag, KNO3, K2SO4 and Fritted Potash applied to soils differing in mineralogical composition and leached with two irrigation waters. Reduction in CEC, exchangeable plus soluble K, and K in the leachate were measured. It is evident that K status of the montmorillonitic and vermiculitic soils differed markedly. There was greatest K fixation with the latter soil. The use of Fritted Potash, when compared to more soluble K sources such as KNO3 and K2SO4, on soils which do not fix K may reduce considerably the amount of K lost by leaching. For soils which fix K in a difficultly exchangeable form, the amount of K fixed from applications of the slightly soluble sources are similar to the amounts fixed from applications of the very soluble sources.
