Summary Saturated sodium‐pyrophosphate extracts were obtained from samples of Sphagnum‐moss peat, sedimentary peat, fibrous peat, disintegrated peat, and muck and were subjected to electrophoretic separation and analysed for organic matter, polysaccharides, and coloured material. The resulting patterns indicated a marked difference between the muck samples and the peat samples. The high exchange‐capacity values obtained for muck samples were associated with the amount of highly charged material rather than with an increase in the charge density of this material. The muck and the fibrous‐peat samples appeared to be end members in a disintegration and oxidation sequence involving many intermediate stages.
