Abstract The organic matter of the A 0 and B h horizons of a podzol has been oxidized with 1:1 nitric acid. About 60% of the organic matter of both materials was converted to CO 2 . In the oxidation product of the A 0 material, succinic, glutaric, adipic, benzene tetra‐ and penta‐carboxylic and picric acids were identified. The oxidation product of the B h material contained benzene tetra‐ and penta‐carboxylic and picric acids but no aliphatic carboxylic acids. The acids identified represented about 5% of the original organic matter of both materials. The results suggest that the organic matter of the B h contained more aromatic structures than that of the A 0 horizon. The possible significance of the acids identified with regard to the chemical structure of the organic matter preparations from both horizons is discussed.
