In each LUS samples were taken for theassessment of: (1) soil physical (texture, porosity, aggregation stability, resistance topenetrationanddensity)andchemical(pH,P,K,Ca,Mg,MO,Al,H+Al,C,H,NandS)quality,(2) soil macrofauna diversity (soil macrofuna groups, and identification to species level ofOligochaeta, Coleoptera, Chilopoda, Diplopoda, Aranae, Formicidae, Scorpionidae,PseudoscorpionidaeandIsopoda)usingpitfalltrapsandhandsortingof25x25cmmonoliths,(3)mycorrhizalcolonization,sporecountsanddiversity,(4)soilmicrobialbiomassandactivity(basal respiration) and, (5) structural community diversity ofArchaea andBacteria using TͲRFLPmolecularmethod.
