Macrofauna invertebrada do solo em sistema integrado de produção agropecuária no cerrado

Abstract

The objective of this work was to evaluate the density and diversity of soil invertebrate macrofauna in a crop-livestock rotation production system under no-tillage. The field experiment was performed in Dourados, Mato Grosso do Sul State, Brazil, on a Typic Hapludox soil, in parcels under a conventional monoculture system, a crop-livestock rotation system under no-tillage and continuous pasture, and a native vegetation fragment. The evaluations were conducted in January 2002, June 2002, January 2003 and July 2003, according to the method recommended by the Tropical Soil Biology and Fertility (TSBF) program. Systems with less anthropic interference showed greater abundance and richness of soil invertebrate macrofauna.
