Resumo: | This work had as objective to compare the communities of Entomobryidae and Isotomidae (Collembola) among no-tillage in three fertility levels, conventional tillage and a natural ecosystem (native grassland). In the no-tillage in low fertility and medium fertility Entomobryidae and Isotomidae had populational picks in the winter and in the summer. In the no-tillage in area of high fertility, there was a populational pick for both families in the summer. In relation to the conventional tillage, Entomobryidae had a populational pick in the winter, and Isotomidae in the winter and in the summer. In the natural ecosystem Entomobryidae presented populational picks in the winter and in the summer and Isotomidae had regular populational fluctuation along the period of the experiment. The final mean density of Entomobryidae was larger in the natural ecosystem, proceeded by the treatments of no-tillage and finally, for the conventional tillage. In relation to Isotomidae, the no-tillage in area of low fertility was superior, coming the conventional tillage soon after, the no-tillage in médium and high fertility, and, finally, the natural ecosystem.
