Composition, properties and formation of Pseudogley on loess along a precipitation gradient in the Pannonian region of Croatia

Climate and relief influence on particle size distribution and chemical properties of Pseudogley soils in Croatia

“…Further, the parent materials of Croatian Pseudogleys usually have the same or even slightly increased clay content compared with the Btg horizons above them (see Bašić, 2013;Rubinić et al, 2014Rubinić et al, , 2015. Given the clay coatings observed in thin sections and the depthrelated trends of the weathering indices (Ti/Al and CIA), Rubinić et al (2014) inferred that the vertical increase in clay content from the topsoil towards the parent material in Croatian Pseudogleys is largely due to lessivage.…”

“…2). Given that parent materials of Croatian Pseudogleys are usually thoroughly altered by pedogenesis, they are morphologically similar to Btg horizons (see Rubinić et al, 2014Rubinić et al, , 2015. Most notably, both Btg horizons and parent materials are usually dominated by RMF (Table 1 and Fig.…”

“…Given the clay coatings observed in thin sections and the depthrelated trends of the weathering indices (Ti/Al and CIA), Rubinić et al (2014) inferred that the vertical increase in clay content from the topsoil towards the parent material in Croatian Pseudogleys is largely due to lessivage. High contents of clay (and RMF) in C horizons can be considered the result of the downward percolation of precipitation water along the cracks (zones of the redox depletions) in the parent material (see Bockheim, 1980;Shaw et al, 2004).…”

“…Soil morphology of profiles 1, 3, and 25 (see Appendix B) is described in detail in Rubinić et al (2014). Additionally, morphology of soil profiles 7, 19, and 28 (see Appendix B) is described in Rubinić et al (2015).…”

“…According to Rubinić et al (2014), parent materials of Pseudogleys in the Pannonian region of Croatia can be characterized as follows. They comprise largely loess derivates, and sporadically brown loess.…”
