O objetivo deste trabalho foi quantificar a densidade e diversidade de grupos da comunidade de macrofauna invertebrada do solo sob diferentes sistemas de produção, bem como analisar a similaridade entre os sistemas avaliados. O trabalho foi conduzido no Município de Dourados, MS, em Latossolo Vermelho distroférrico típico, sob os seguintes sistemas: sistema convencional (SC), sistema plantio direto (SPD), sistema integração lavoura/pecuária (SILP), pastagem contínua (PC) e vegetação nativa. As amostragens foram realizadas em três safras de verão e de inverno. Os valores de densidade total da comunidade de macrofauna invertebrada de solo, nos sistemas SPD, SILP e PC, foram similares, no entanto, o SPD apresentou a maior diversidade de grupos. Na safra de verão, observou-se similaridade entre os sistemas SPD e SILP e entre o SC e PC; e na safra de inverno, a similaridade foi entre os sistemas SPD, SILP e PC.
The objective of this work was to quantify the density and diversity of soil invertebrate macrofauna community, in different production systems, and also to evaluate the similarity among them. The study was carried out in the Municipality of Dourados, MS, Brazil, in a Typic Hapludox under the following systems: conventional system (CS), no-tillage system (NTS), crop/livestock integration system (CLIS), continuous pasture (CP) and natural system. Samples were collected during summer and winter cropping seasons. Total density and diversity of the soil invertebrate macrofauna community in the NTS, CLIS, and CP systems were similar. However, NTS showed the highest diversity. In summer, similarity was observed between NTS and CLIS, and between CS and CP, with regard to the soil invertebrate macrofauna community. In winter, similarity was among NTS, CLIS and CP.
