The Soil Structure Rapid Diagnosis - DRES - was adopted as an instrument to assess soil quality, followed by the collection, identification and measurement of soil fauna using Pitfall traps. Different types of management were evaluated in three rural properties: A - modified conventional planting; B - no-tillage and conventional tillage and C - minimum cultivation. The largest record of group of epigeal fauna occurred in the management with CM, followed by the PD. The lowest activity records were verified in the PC area. The greatest stability of soil aggregates occurred in the PD and CM, and the lowest in PCM and PC. It is concluded that the indicators of Soil Quality adopted allow a technical analysis in the decision making for adoption of vegetable production systems. It is interpreted that the absence of mechanization associated with the planting of Direct Planting and Minimum Cultivation tend to promote an adequate environment for soil conservation and the presence of fauna. A relationship should be established by adopting more indicators of soil sustainability and productivity, to identify the ideal management that promotes production, preservation and profitability to the producer.  aNo-tillage  aSoil fauna  aCultivo Mínimo  aPlantio Direto  aDiagnóstico Rápido da Estrutura do Solo  aFauna do Solo  aMinimum cultivation  aRapid Soil Structure Diagnosis1 aDONAGEMMA, G.
