Abstract
A morphometrical analysis was made of soil lessivé surface layer (0–8 cm) after different cultivation treatments and in changeable weather conditions. The basic parameters were discussed (macroporosity, i.e. the relative area of pore cross-sections, quantity, mean pore crosssection size characteristic of macropores sized above 42 μm). It was found out that macroporosity is the factor which can best describe changes in the soil structure caused by different external conditions. The other parameters allow for a deeper analysis of soil structure changeability. The structure of the surface layer of the tested soil lessivé developed from silt showed low stability and high susceptibility to compaction by rain.
