The depth and dynamics of the goundwater table throughout the warm sea
son are crucial factors in soil formation on coarse-textured deposits
in glaciofluvial plains. Also, in spring, an impermeable layer of froz
en soil has a substantial effect on the pedogenesis and is responsible
for soil waterlogging and the occurrence of perched water above the f
rozen horizon of soils of automorphic (geochemically independent) and
superaquatic landscapes, Such soil conditions favor the development of
gleyification, which is realized under conditions of a stagnant and p
ercolative water regime. Pseudofibers occurring in nongley, deeply gle
y and gleyic soils largely control the wetness of enclosing horizons a
nd plant water supply because of an increased water-holding capacity a
nd poor permeability of pseudofibrous neoformations.
