description A major concern related to agricultural management systems used by the man lies on the effects on biological processes in the soil, whose action within ecosystems aiming at the farm, modifies the intensity of these processes under use of techniques that exclusively aim to maximize crop yield. One of the challenges of research in soil biology is precisely understand the impacts on the complex interactions of all soil organisms at the community level by the management that are critical in maintaining soil quality. The objective of this work was to evaluate the influence of management practices on fruit trees (mango, guava and coconut trees) in the composition and distribution of soil arthropods (edaphic macrofauna, mesofauna) and on microbial biomass, the activity and interaction with the chemical, physical and environmental attributes. The study of soil arthropods began in July 2013 and followed until May 2014, with measurements at four periods. Microbiological soil activities were evaluated by the determination of microbial soil properties (RBS, CBM, NBM, NBM / N, qCO2 and qMIC). It was found that the soil arthropods were sensitive to changes arising from different soil tillage systems, allowing it to be used as an important tool to apply as bio-indicators of the quality of edaphic system. The system with guava cultivation proved to be unstable over time in relation to the structure of the community of soil arthropods. The system with coconut tree cultivation allows for better soil quality, increase in abundance and species richness of invertebrate macrofauna. The microbial biomass carbon (MBC), microbial biomass nitrogen (NBM) and the metabolic quotient (qCO2) were the main microbiological soil properties responsible for identifying dissimilarities between areas. Correlations between microbiological and faunal characteristics of the soil were low with significant correlations only between Collembola, NBM and NBM / N. === Uma das grandes preocupaÃÃes relacionadas aos sistemas de manejo agrÃcola adotado pelo homem reside nos efeitos sobre os processos biolÃgicos que ocorrem no solo, cuja aÃÃo dentro dos ecossistemas visando à exploraÃÃo agrÃcola, modifica a intensidade desses processos em virtude do emprego de prÃticas que objetivam exclusivamente a maximizaÃÃo da produÃÃo vegetal. Um dos desafios da pesquisa em biologia do solo à justamente entender os impactos do manejo sobre as complexas interaÃÃes de todos os organismos edÃficos ao nÃvel de comunidade que sÃo fundamentais na manutenÃÃo da qualidade do solo. Objetivou-se avaliar a influÃncia dos manejos em cultivos de fruteiras (mangueira, goiabeira e coqueiro) na composiÃÃo e distribuiÃÃo dos artrÃpodes de solo (mesofauna e macrofauna edÃfica) e sobre a biomassa microbiana, sua atividade e interaÃÃo com os atributos quÃmicos, fÃsicos e ambientais. O estudo dos artrÃpodes edÃficos teve inÃcio em julho de 2013 e seguiu atà maio de 2014, com coletas realizadas em quatro perÃodos. As atividades microbiolÃgicas do solo foram avaliadas mediante as determinaÃÃes dos atributos microbianos do solo (RBS, CBM, NBM, NBM/N, qCO2 e qMIC). Constatou-se que os artrÃpodes de solo mostraram-se sensÃveis as alteraÃÃes ocasionadas pelos sistemas de manejos do solo, possibilitando a sua indicaÃÃo como importante ferramenta para aplicar-se como bioindicadores da qualidade do sistema edÃfico. O sistema com cultivo de goiabeiras mostrou-se instÃvel ao longo do tempo em relaÃÃo à estrutura da comunidade dos artrÃpodes de solo. O sistema com cultivo de coqueiros propicia melhores caracterÃsticas do solo e aumento na abundÃncia e riqueza de espÃcies da macrofauna invertebrada. O carbono da biomassa microbiana (CBM), nitrogÃnio da biomassa microbiana (NBM) e o quociente metabÃlico (qCO2), foram os principais atributos microbiolÃgicos do solo responsÃveis por identificar dissimilaridades entre as Ãreas. CorrelaÃÃes entre as variÃveis microbiolÃgicas e faunÃsticas do solo foram baixas, com correlaÃÃes significativas somente entre Collembola, NBM e NBM/N.
