Various processes exercise influence on the soil macrofauna through intervention in the physical,
chemical or biological characteristics of the ecosystem. The aim of this study was to evaluate
the potential influence of different levels of chemical fertility associated to different contents of
kaolinite and gibbsite on the soil macrofauna under pastures in the Brazilian Cerrado region. In
this regard, a region to study was selected in the Federal District (near Brasília) and in the city of
Formosa, Goiás state. A chemical pre-analysis was carried out of the soils to determine the
exchangeable Ca and Mg as well as those of kaolinite and gibbsite through thermogravimetric
analysis (TGA) with the aim of calculating the ratio kaolinite / kaolinite+gibbsite (RKGb). These
two parameters (Ca + Mg and RKGb) allowed the choice of four groups of soils, which were:
Group I (Ca + Mg from 0.5 to 1.0 cmolc kg-1 and RKGb from 0.4 to 0.6); Group II (Ca + Mg from
0.5 to 1.0 cmolc kg-1 and RKGb from 0.8 to 1.0); Group III (Ca + Mg from 2.0 to 4.0 cmolc kg-1
and RKGb from 0.4 to 0.6) and Group IV (Ca + Mg from 2.0 to 4.0 cmolc kg-1 and RKGb from
0.8 to 1.0). Macrofauna was sampled following the TSBF method, collecting blocks of 25 × 25 ×
30 cm where, after manual collecting, all of the individuals were counted which afterwards were
identified as belonging to groups. The data were submitted to a principal component analysis
(PCA) with the aim of grouping the variables which came closest to explaining the behavior of
the macrofauna in the four soil groups selected. The groups identified in decreasing order of
total density are: Isoptera, Hymenoptera, Oligochaeta, Coleoptera, Diplopoda, Chilopoda,
Diptera, Hemiptera, Lepidoptera, Araneae, Homoptera, Symphyla, Scorpione e
Pseudoscorpione. The frequency of individuals in the litter is very low and represents less than
1% of the total; the greatest concentration of macrofauna in soils under pastures in the Cerrado
region occurs in the superficial layer 0-10 cm. The predominance of Isoptera is more accentuated
in the soils having low chemical fertility (low Ca + Mg) and there is a higher density of Oligochatea
(earthworms) in soils with high RKGb. MenosVarious processes exercise influence on the soil macrofauna through intervention in the physical,
