PSEUDOFIBERS OF COARSE SOILS WITH DIFFERENT DEGREES OF HYDROMORPHISM IN ALLUVIAL PLAIN LANDSCAPES

In the automorphic Light Brown soils of vast alluvial plain landscapes , pseudofibers are distinguished from the enclosing horizons by an inc reased content of mud, nonsilicate iron, and organic matter, a very fi ne consistency, and a high moisture capacity. They make a noticeable c ontribution to the moisture supply to plants. With the growth of hydro morphism (Highly Gleyed and Gleyey soils), the number of pseudofibers decreases, and their differences from the enclosing horizons weaken. P seudofibers are not formed in gley soils.
