The aim of this studies was to determine differences in the number of selected groups of organisms belonging to soil macrofauna in three tillage systems, ie. conventional, reduced and zero-tillage on winter wheat crops. The experiment was carried out at the Agricultural Experimental Station Swojec belonging to the Wroclaw University of Environmental and Life Sciences, Poland, in 2004–2006. Soil macrofauna abundance was assessed through soil samples taken directly from the field (25 × 25 × 30 cm). On the basis of obtained results it was shown that conventional ploughing system decreased the number of macrofauna, in particular as compared to zero-tillage, as well as to reduced tillage system. Such relations were found both for beneficial ground beetles, rove beetles, earthworms as well as for potentially harmful polyphagous soil pests (Elateridae, Agrotinae, Melolonthidae).
