摘要：

Romania owns important areas with High Natural Value (HNV) agriculture systems. The aim of the paper was to assess the biodiversity aspects of microbial communities in two soils from the areal selected for HNV payments, that belongs to the Pilot Zone II in Lupac, Caras-Severin County: P3-cultivated in conventional system with maize for forage and P4-under HNV agriculture system with forage plants, mainly leguminous, between abandoned orchard trees. Microbial counts and taxonomy of bacteria and fungi have been determined (by dilution plate method). Diversity index of Shannon and similarity index between the habitats have been calculated, as well as soil respiration potential (estimated by substrate-induced respiration method). Microbial diversity varied from 3 to 9 species. Dominant species included Pseudomonas fluorescent, Bacillus spp. and cosmopolitan genera Penicillium and Trichoderma, with role in improving the control of phytopathogens in rhizosphere and nutrients uptake by plants, aggregation of soil, cellulose decomposition and carbon sequestration. Circular paper chromatograms provided information on biological quality of studied soils.
