- Аннотация: Equal or comparable contents of Fe and Al extractable by Tamm and Mehra–Jackson solutions have been revealed in all the horizons of a loamy muckypeatypodzolic gley soil on binary deposits. The content of Si extractable by the Mehra–Jackson solution has exceeded that of oxalatesoluble Si by an order of magnitude. The distributions of Al in the Tamm solutions from the entire soil and its fractions of 1–5 and >5 μm are of accumulative type with a maximum in the mucky H horizon and a gradual decrease of the content with depth in relation with the analogous distribution of Al–organic complexes. The maximum content of oxalatesoluble Al in the clay fraction has been found in the eluvial ELg horizon, which can be due to the partial dissolution of Al hydroxide interlayers in soil chlorites. The distribution of Fe in the entire soil has two maximums, in the H horizon due to the accumulation of Fe–organic complexes and in the concretion rich ELcng horizon due to the accumulation of Fe hydroxides. Depletion of oxalatesoluble Fe in the eluvial ELg horizon has been observed in all the fractions, which can be related to its mobilization and removal under strongly acidic conditions and the development of reductive processes, as well as the enrichment of the concretionrich horizon with these compounds because of an increase in pH and the development of conditions favorable for water stagnation and Fe segregation.
