Sumario:The objectives of this study were to evaluate the effects of cover crops (CC) and crop sequences on some soil properties and macrofauna abundance; and the influence of these properties on the presence of the main macroinvertebrates’ families. We worked on an experiment installed in Zavalla (Santa Fe) which treatments included CC of vetch and triticale before maize and soybean, respectively, and two treatments of fallow with the same cash crops. Samplings were done after CC (Mcc-b) and cash crops (Mf) cycles. Among edaphic properties, particulate organic carbon registered an increase in sequences with CC, while mechanical penetration resistance and water stable aggregates percentage showed short term variations that were linked with CC´s root development, particularly after vetch suppression. Changes in the abundance of macrofauna were associated with edaphic conditions generated by the treatments. In Mcc-b there was a differentiation between samples of both CC, and between them and fallow ones, while in Mf samples which included CC showed more favorable edaphic conditions in relation with fallow ones. Finally, CC leaded the presence of macrofaunal organisms from different trophic groups due to the coverage generated and the input of food resources.
