Resumo: Soil management systems with different crop residue inputs and different soil mobilization degrees, influence microbial community structure and activity, affecting crop productivity and soil quality. In the present study, we evaluated the microbial attributes of a Paleudult with three crop systems (winter fallow or two crop rotations) under conventional tillage or no-tillage, having a natural pasture as the reference system. Microbial biomass, respiratory activity, activity of β-glicosidase, urease, arylsulphatase and acid phosphatase, besides metabolic diversity, were evaluated. The analysis of microbial biomass and respiratory activity, as well as the index of enzymatic activities, revealed that no-till and natural pasture were quite similar, differing from soil under conventional tillage, with no influence of crop systems on these parameters. Regarding metabolic diversity, it was observed a distinct pattern between conventional tillage and the all other treatments. As a whole, considering the microbial indicators analyzed in this research, no-tillage resembled to natural pasture and the crop systems did not impact the biochemical indicators evaluated.

No presente trabalho, foram avaliados os atributos microbianos de um Argissolo cultivado em três sistemas de culturas (pousio no inverno e duas rotações de culturas), implementados sob preparo convencional ou plantio direto, utilizando-se o campo nativo como referencial. Foram estimadas a biomassa microbiana, a atividade respiratória, as atividades das enzimas â-glicosidase, urease, arilsulfatase e fosfatase ácida, além da diversidade metabólica da microbiota. As análises de biomassa e de atividade respiratória, bem como o índice das atividades enzimáticas, indicaram comportamento semelhante entre solo sob plantio direto e campo nativo, os quais diferiram daquele sob preparo convencional, não havendo diferenças quanto aos sistemas de culturas. Em relação à diversidade metabólica, a determinação demonstrou um padrão distinto entre o preparo convencional e os demais tratamentos. De forma geral, para os indicadores empregados no presente trabalho, o plantio direto assemelhou- se ao campo nativo e os sistemas de culturas utilizados não promoveram impactos significativos sobre qualquer dos indicadores bioquímicos utilizados. Departamento de Diagnóstico e Pesquisa Agropecuária.
