CXXV1II (2004), 223-232 and black poplar (Topuletum nigro-albae Slavn. 1952) and the forest of spreading elm and narrow-leaved ash (Traxino-Ulmetum laevis Slav. 1952). The pedogenesis of the study area is characterised by distinct effects of the Danube hydrological regime. As a rule, the soil texture is of loamy to sandy character. Only in micro-relief depressions away from the riverbed (mostly in the surface part) may the texture be somewhat heavier (clayey loam to light clay). A characteristic feature of the soil in this region is a prominent texture stratigraphy. Apart from alluviation as a geological andpedogenetic process, these forest ecosystems are characterised by high organic production, which is sporadically significantly manifested in pedosphere humisation. The dominant soil type was found to be fluvisol, regularly carbonate, while gleysol and humofluvisol are represented to a much lesser degree. All these three soil types differ from one another in terms of ecological production. It should be pointed out that ecological-productive differences within one type are in some cases much larger than among the types, which is closely connected to the features of the water regime properties and the texture. From the aspect of pedotaxonomic nomenclature, in our view it is not necessary to-classify some soils from the alluvial plain into a separate type. This refers to humofluvisols with a shallow A-horizon. An approach to the WRB classification seems to be a better solution, according to which the majority of such soils are classified into a group offluvisols (except those with the A-horizon thicker than 25 cm).
