The content of the total potassium in particular granulometric fractions increases from a sand fraction (1-0.1 mm) to fine silty clay (0.002-0.005 mm), while in the clay fraction it usually decreases. The most diverse fractions in terms of potassium content are those extracted from mountain soils developed from old Cretaceous and Tertiary forms. Granulometric fractions extracted from soils developed from loessial sediments are homogenous with regard to the total potassium content. In those sediments there is a close parallelism between the amount of a given fraction in the soil and the amount of potassium contained in the fraction. This relation laid behind this attempt to calculate the coefficients for the total potassium content in soils on the basis of the granulometric analysis.
