In the humid tropic the soil fauna has fundamental importance for decomposition and nutrient
cycling. Such variation can indicate differences in the sustainability of management systems.
This objective this study was to evaluate the soil fauna in an alley cropping implanted in 2002
and designed to improve soil fertility. The completely randomized bloch with 4 replications test
in 6 trataments comprising mixtures of two legume trees with high quality residues - Leucaena
leucocephala (Lam.) DeWit) and Cajanus cajan (L.) Druce) and two legume trees of low quality
with residues - Clitoria fairchildiana (Howard) and Acacia mangium, as follow: Clitoria + Cajanus
(Cl+Cj); Leucaena + Cajanus (Lc+Cj); Acacia + Cajanus (Ac+Cj); Clitoria + Leucaena (Cl+Lc);
Leucaena + Acacia (Lc+Ac) and Control (without legume trees). The legumes were pruned in
January 2007 at 50 cm height and pruning was between the corn and cassava rows. Soil fauna
was captured May, 4 months after pruning, with pitfall traps using 300 ml plastic glasses. Five
traps were placed in each tratament, arranged in zig-zags resulting 30 traps per block. The
traps were activated after 2 days, in order to reduce the effects of excavation. The pitfall traps
remained in the field for 7 days, after which transfered to the laboratory, all specimens washed
and identified to level of major taxonomic groups. Diversity and eveness were evalueted with
Shannon´s and Pielou indices, and similarity between tratamentsevaluated with cluster analyses.
Mixtures of Lc+Cj presented the highest number of individuals following by Cl+Lc, the control
tratament and Ac+Cj mixtures had the lowest abundance of soil fauna. Our resultes suggest that
soil organisms prefer habitats with high residue quality. The groups with highest dominance
were mites and springtails, 65% (Lc+Cj), 52% (Cl+Lc), 37% (Control) and 55% (Ac+Cj). This
fact could be explained by the probable increase of the microbial and fungi populations during
the rainy season serving as food for the Collembolas. Some Acari, fungivorous, predators of
Collembola or detritivorous, which may have likewise benefitted by the increase in the microbial
population. These organisms possess short life cycles and they response storngly to food supply
by rapid reproduction we did not find any difference in richness or number of groups between
trataments, but was higher in the control than in the others trataments, indicating a greater activity
of soil fauna without residue aplication. This could be explained by fact that the contro plot were
situated in locations between the oders trataments, capturing soil organism migrating in search
for protection and food. Cluster analyses indicated that similarity was high between Cj+Ac and
Lc+Cj trataments suggesting that the fauna of the soil seeks for residue of high quality, and at
the same time refuge offered by the residues of low quality. MenosIn the humid tropic the soil fauna has fundamental importance for decomposition and nutrient
