Arthropods are part of important functional groups in soil and little is known about their composition in differently used agroecosystems across larger spatial scales. We analysed the qualitative and quantitative structure of soil arthropods with emphasis on ground beetles in different agroecosystems in relation to the various factors (soil physical properties) that Slovakia as a highly diversified country offers. Research was conducted in 4 different soil types (Arenosol, Cambisol, Fluvisol, Leptosol) at 6 study sites located in three different ecological zones with two different land use types (arable land – AL and permanent grasslands – PG). Ten orders of soil arthropods were identified, of which the most abundant was the order Coleoptera, specifically the Poecilus cupreus species in the Carabidae family. The analysis of variance confirmed significant effect of land use type on arthropod number and ecological gradient on arthropod biomass and soil temperature. The number and biomass of arthropods was nearly twice as high in PG plots compared to AL plots with the exception of two study sites located in sub-mountain and mountain regions with the dominance and proximity of extensive forest and grassland ecosystems. From the ecological gradient point of view, the highest arthropod biomass was recorded in the mountain ecological zone.
