ABSTRACT
The epi-edaphic macrofauna are important for soil functioning and their populations are sensitive to soil
management. In this study, the effect of integrated and continuous cropping systems on the edaphic macrofauna
was evaluated in a long-term experiment at Embrapa Cerrados in Planaltina-DF, Brazil. Sampling took place
in the wet and dry seasons of 2019, using pitfall traps in nine treatments with two replicates, including croplivestock
integration with or without cover crops and with minimum cultivation or no-tillage; continuous
pasture of pure grass or intercropped with legumes; continuous tillage with and without cover crops; and a
fragment of native Cerrado vegetation. A strong seasonality was observed, with 56 indicator macrofauna
morphospecies in the rainy season and 38 in the dry season. Integrated systems in the cropping phase had
greater dominance of some groups of fauna, such as ants, beetles and moth catterpillars, leading to lower
Shannon diversity values. No-tillage, integrated systems with cover-crops and the native Cerrado had the
highest morpho-species richness, showing potential as repositories of local epi-edaphic macroinvertebrate
biodiversity.
