Abstract

The aim of the investigation was to define the extend of pedogenethic processes by analysis of colour changes in groundmass of each genetic horizon. The object of the research were Chromic soils developed from red deposits of Lower Triassic (Buntsandstein) in the Holy Cross Mountains. Micromorphological studies were made with polarization microscopes Olympus BX- 41 and Olympus SZX-10. Image analysis was conducted with software program AxioVision 4.5 with Auto Measure module. The application of advanced methods of digital data analysis allowed for the quantitative compilation of measurement figures in thin sections. On the basis of micromorphometrical data designated objective numerical indicators, which allowed comparison groundmass color between each genetic horizon. Statistical analysis by ANOVA test confirm that groundmass color measured in RGB scale in investigated horizons are almost the same. Obtained results evidence that characteristic red color of soil substrate in analyzed soils developed from Lower Triassic rocks originated from the bedrock color. This fact indicates low extent of the pedogenic processes.
