Método alternativo para estudar a fauna do solo

Abstract

Study of soil organisms population may not detect differences of organisms number due to the difficulty of pitfall installation methods routinely used. However, to a better practice and determination of population level of soil organisms, it was evaluated an alternative methodology to the pitfall Tretzel (modified). The method is called Provid, for the collection of the soil organisms, proposed by the authors of this work. The two methods were installed in nine different areas, with three replication for each method. The areas differed in terms of location, soil type and vegetable covering. The appraised parameters were richeness, abundance and Simpson´s index. As results, it was not found significant statistical differences for the two methods of collection of organism´s edaphios among the nine analyzed areas, for the appraised parameters. Therefore, that the methodology of collection of the soil organisms for the Provid method can be used as efficient as the pitfall Tretzel modified method. The Provid method is practical and easy to be managed.
