This study examined courses of sorption and of leaching with distilled water of ions Fe²⁺, Fe³⁺, and Mn²⁺ in non-deoxidized and unoxygenated loessial soil material. The sorption was measured using a dynamic method. ODR and Eh were measured as indices of soil oxygenation. It was found that unoxygenation of loessial soil material increases the sorption of ions Fe²⁺, Fe³⁺, and Mn²⁺ in samples of pH 4.8, while in samples having pH 6.5 an increased sorption was only found for Fe³⁺ ions.
