Data obtained by dry and wet sieving of soil samples collected from two forest, two meadow and two cropland pseudogley profiles were used to evaluate the aggregate size distribution and aggregate stability of pseudogleys in the surroundings of Kraljevo. The samples were taken from humus, eluvial and illuvial horizons. The structure of these soils is unfavourable, particularly in the topsoil of cropland pseudogleys, especially as regards the content of agronomically most favourable stable aggregates between 1 and 5 mm in diameter. This content in the Ahp horizon is considerably lower than in the Ah horizons of forest and meadow soils. Pseudogleys under forests have a more favourable structure compared to meadow pseudogleys and particularly cropland soils. Due to the low water stability of macroaggregates, these soils under all three land use types exhibit a high degree of compactness.
