| Resumo: |
This work had as objective to compare the communities of Sminthuroidea and Onychiuridae (Collembola) among no-tillage in three fertility levels, conventional tillage and a natural ecosystem (native grassland). In the conventional tillage and in the no-tillage in area of medium fertility, the community of Sminthuroidea had regular fluctuation along the period of the experiment, but wtth low densities. The no-tillage in area of high fertility presented a populational pick in the autumn; the no-tillage in area of low fertility, in the spring; and, the natural ecosystem, in the summer. As the final mean density of the population of Sminthuroidea, was observed that the no-tillage in area of low fertility went numerically superior to the others, proceeded by the natural ecosystem, no-tillage in area of high fertility, conventional tillage, and, finally, no-tillage in area of medium fertility. Onychiuridae had three populational picks in the no-tillage in area of low fertility: being a larger in the winter and other two, smaller in the summer and in the autumn. In the no-tillage in area of medium fertility presented only a populational pick in the winter. In the other treatments there was not significantly populational picks. In relation to the final mean density ofthe community of Onychiuridae, the no-tillage plantation in area of low fertility was superior, proceeded by the other treatments of no-tillage, and, in third plan, the natural ecosystem and the conventional tillage.
