Summary Twenty‐four soils from north‐east Scotland have been subjected to differential extraction techniques to determine the effect of hydromorphism on various Fe, Mn, and A1 fractions. There were pronounced losses of dithionite‐extractable Fe and Mn from gleyed horizons, but the 'silicate‐Fe’fraction appeared to be relatively unaffected. The oxalate‐extractable Fe and A1 fractions also decreased in response to gleying. The ratio of the oxalate‐ to dithionite‐extractable Fe fractions (Fe 0 /Fe d ) increased in gleyed horizons, presumably due to variations in the rate of ageing and crystallization of amorphous Fe oxides and hydroxides.
