摘要

Abstract Gleying and enhancement of hydromorphism in wetland soils due to Fe(III) reduction entail a series of degradation processes. The resistance of wetlands to degradation can be calculated from the content of potentially reducible iron, Fe(III)~(pr), which is found from the van Bodegom equation taking into account the contents of oxalate-soluble iron Fe~(ox)and dithionite-soluble iron Fe~(dit)in the soil. In addition, this makes it possible to distinguish relict and actual gleysols. The van Bodegom equation is applicable to soils from which the oxalate solution extracts only amorphous and poorly crystallized iron compounds, which are quickly reduced by Fe-reducing bacteria. These soils have a low proportion of Fe(II) (no more that 15% of the total iron), as well as an accumulative profile distribution of Fe~(ox). The van Bodegom equation is unsuitable for calculating the Fe(III)~(pr)content in soils with a high proportion of Fe(II) and a nonaccumulative profile distribution of Fe~(ox).
