Mineralogical composition of solod

Abstract

The objective of the present study was to investigate in detail the mineralogical soil composition in order to obtain a clearer picture of the extent to which it and the related pedogenetic process taking place in locations marked as solods on the R = 1:50,000 soil map of the Vojvodina Province (Nejgebauer et al., 1971) correspond to the solodization process described in the literature. In the profiles of the soils we studied in the regions of western Bačka and southern Srem, illite was the dominant clay mineral, but some specific phenomena were also observed that from the pedogenetic point of view are typical of a soil type previously described in the literature (solod), namely the greater contribution of quartz, in the surface horizons of the total soil sample (which is indicative of clay mineral decomposition and destruction), the predominance of illite and kaolinite in the surface horizons of the clay fraction, and the fact that in the Bt,g horizon the kaolinite content decreased considerably and illuviation occurred of chlorite and vermiculite, two highly dispersive minerals from the smectite group.
