The patchy character of the distribution of Chernozems and Luvisols formed on loess is often observable on the pedological maps, on a large scale, in Czechia. The focus of the paper is to examine the features of the soil catena of Hrušov (Czechia), which is characterized by the simultaneous presence of Chernozem, Luvisol and Luvic Chernozem – without obvious environmental reasons. A catena of only 330 meters is considered a system of transformation between these soils. Along with field work and the pedological analysis, we used the soil micromorphology method to understand the processes of pedogenesis. We concluded that the presence of considerably different soil types on a small scale is due to intensive agriculture. We found that the present Chernozem is formed on the Luvisol by retrograde soil evolution, which included a shift in the vegetation, erosion, and recarbonation. The evolution of Luvisol in the lower part of the catena has been considerably modified.
