A voltammetric method was used for the determination of stability constants (log K) of Mn(II)‐complexes in soils. Log K values were of the order of 2–5, being largest at the stage of intensive decomposition of organic matter. The complexing agents were primarily negative in electric charge, and could be retained by soils containing free iron oxides.
