Soil invertebrates play key roles in determining soil suitability for agricultural production and realizing sustainable farming systems. They include an enormous diversity of arthropods, nematodes, and earthworms. However, this fauna suffers from the impact of agricultural activities with implications for the capacity of soil to maintain its fertility and provide ecosystem services. Some agricultural practices may create crucial soil habitat changes, with consequences for invertebrate biodiversity. In the few last decades, especially under intensive and specialized farming systems, a loss in soil ecosystem services has been observed, as a result of the reduction in both the abundance and taxonomic diversity of soil faunal communities. On the other hand, agricultural practices, based on sustainable soil management, can promote useful soil fauna. Therefore, the concerns about the sensibility of soil biota to the agricultural practices make it urgent to develop sustainable management strategies, able to realize favorable microclimate and habitats, and reduce the soil disturbance.Research & information: generalbicsscAporrectodea caliginosaAporrectodea roseaaxonchiumbiodiversitybioenergybioindicatorsbiological controlco-occurrence patternscover cropscrop rotationearthwormsecosystemecosystem servicesfarming systemsgossypiumGossypiumground-dwelling arthropodsheavy metalshelicotylenchusHordeum vulgare L.invertebratesland managementLumbricidaeLuvisolsmacrofaunamanagement intensitymesofaunamountain agriculturenatural enemiespear pestsphosphorus fertilizersphosphorus-solubilizing microorganismspitfall trapspost-harvest residuespratylenchusrenewable resourcesreniformsoilsoil biodiversitysoil biotasoil degradationsoil invertebratessoil moisturesoil organic mattersoil pHsoil propertiessoil qualitysoil temperatureSouth Tyrolsustainabilitysustainable agriculturetraditional managementtylenchorhynchusvertisolvertosolVicia faba L. ssp. minorvineyardvineyard managementwheatZea maysResearch & information: generalBocchi Stefanoedt302956Orlando FrancescaedtBocchi StefanoothOrlando FrancescaothBOOK9910674036503321Impact of Agricultural Practices on Biodiversity of Soil Invertebrates3059263UNINA
