Integrated crop-livestock systems (ICLS) have been recommended in Brazil as an alternative to
conventional and/or continuous land use systems and have increased production of both crops
and livestock. ICLS systems that seem to be the best for conserving diversity and sustaining
high levels of abundance of the macrofauna and are strongly promoted by agronomic research
in Brazil. We hypothesized that the adoption of RMPs, mainly ICLS based in no-tillage, would
have a favorable effect on the development of an abundant and diverse soil and litter fauna,
which in turn would assist in restoring soil fertility and site productivity. In this regard, the objectives
of this study were estimate the effects of integrated crop-livestock systems, associated with two
tillage and fertilization regimes, on the abundance and diversity (measured by morphoespecies
richness) of the macrofauna in comparison with continuous systems. Four different soil
management systems were studied: continuous pasture; continuous crop; crop/pasture rotation
and pasture/crop rotation. The native Cerrado was used as a reference condition. Macrofauna
was sampled with three replicates for each land use systems (each plot 40 x 50 m) according
TSBF methodology and all individuals were counted and identified at the morphoespecies levels.
Total density and diversity at morphoespecies levels was determined for each plot. A total of
194 morphospecies were found, distributed among 30 groups. The most representative groups
observed, in order to decrease of density, were: Isoptera, Coleoptera larvae, Formicidae,
Oligochaeta, Coleoptera adult, Diplopoda, Hemiptera, Diptera larvae, Arachnida, Chilopoda,
Lepidoptera, Gasteropoda, Blattodea and Orthoptera. Soil management systems and tillage
have impacts on the structure of soil macrofauna communities in Cerrado soils. Integrated
systems (crop/pasture and vice-versa) associated to no-tillage present more favorable conditions
for the development of soil macrofauna (Coleoptera and Oligochaeta) in comparison with
continuous systems and represent alternative land use systems which are useful for soil
biodiversity conservation compared to conventional and continuous systems.
Index terms: soil invertebrates, biodiversity, crop-pasture rotation, no-tillage, soil quality MenosIntegrated crop-livestock systems (ICLS) have been recommended in Brazil as an alternative to
