Studies on Fe oxides have facilitated the interpretation of past and present
pedogenetic processes (INDA JUNIOR & KAMPF, 2005), and the mapping and classification of soils (SANTOS et al., 2013).
Low values of Xfd probably indicate beginning
pedogenetic formation of magnetic particles in soils.
Elevated proportion of clay fraction in the Bt horizon indicates the process of
pedogenetic clay differentiation.
The horst-tops were colonized by tropical lush vegetation due to the local warm-humid climate, as indicated by their palynologic and plant assemblages (Del Rio, 1984; Rees et al., 2000) and the
pedogenetic evidence (laterites and calcretes).
Diagnostic properties, epipedons and subsuperficial horizons of soil profiles were identified in order to analyze and classify
pedogenetic processes.
Contribution of different proton sources to
pedogenetic soil acidification in forested ecosystems in Japan.
Pedogenetic changes in the quantity and distribution of textural and chemical soil constituents during thirty years.
Such a scalar does not work so well in the case of wet mineral soils, as here the hydrological conditions overshadow the normal
pedogenetic processes.
Despite of the relative homogeinity of the
pedogenetic factors (landscape, parental materials, climate, waters, vegetation), within the basin there is present a large enough variety of soil cover, thus being identified soils belonging to the seven classes: Cernisols, Luvisols, Pelisols, Hydrosols, Salsodisols, Protisols and Anthrosols.
The dominant
pedogenetic processes that formed the soils were the following: structure formation, organic matter accumulation, loss of bases and acidification, desilication, fast weathering, and the formation of noncrystalline (short-range order) minerals and gibbsite.
