The edaphic fauna of the podzolic chernozem in the northern zone of the Republic of Moldova has been investigated. Invertebrates’ testing was carried out from semi-profiles around the main profile at a distance of 5-10 m by manual sampling of soil layers to the depth of soil fauna occurrence. The highest values of invertebrates’ abundance (84.8 %) were registered in the upper horizon and litter in the natural chernozem. Number of invertebrates constituted 352.0 ex m-2 and Lumbricidae family - 277.3 ex m-2, biomass - 89.5 and 68.5 g m-2, respectively. The natural chernozem contained 10 families of invertebrates and its trophic pyramids were stable. Saprophagous of Aporrectodea rosea, Aporrectodea caliginosa and Lumbricus terrestris predominate in the composition of the edaphic fauna. Species of Calosoma inquisitor, Lebia cruxmino, Carabus coriaceus, Lilioceris merdigera, Clubiona stagnatilis, Lucanus cereus, Lithobius forficatus and Melolontha melolontha have also been identified. Degradation of the faunal complex in the arable chernozem has been manifested in a decrease of abundance, biodiversity and disruption of trophic connections.
