Deforestation and conversion of forest into farmland, traditionally by slash-and-burn clearing, is
harmful to the soil fauna, which is sensitive to human impact as well as to inherent characteristics
of the particular ecosystem, such as climate, soil and vegetation. We estimated the soil
macrofauna community in mulched and non-mulched secondary forest of different age groups
in small farms of the Tarumã-Mirim rural settlement, located 30 km north of Manaus, Amazonas.
The secondary forest biomass was cut and chopped (September 2006) by a ?Tritucap? tractor
used as an alternative to fire for smallholders. Samples were collected in three secondary forest
of different age groups: 2, 5 and 10 years (mulched secondary forest) and in three control
secondary forest of the same age groups (non-mulched) at the beginning of the rainy season
(December 2005, precipitation: 322 mm) and during the rainy season (March 2006, precipitation:
377 mm). The soil macrofauna was sampled applying a modified TSBF (Tropical Soil Biology
and Fertility) method, by randomly collecting five 50x50x20cm deep soil blocks along a 50 m
transect in each system. Predominant factors of soil macrofauna density in different mulched
and control pastures were obtained by Principal Component Analysis (PCA) using the ADE4
program. The predominant taxonomic soil macrofauna groups in the control and secondary
forest were Formicidae, Oligochaeta, Isoptera, and Isopoda. At the beginning of the rainy season,
the PCA explained 57.1 % of the total variance. Factor 1 explained 39.9 %, correlating the
communities of Aranea, Blattaria, Coleoptera, Diplopoda, Formicidae, and Opilon and factor 2
(17.2 %) correlating the communities of Scorpions, Pseudoscorpions, and Uropyge. During the
rainy season, the PCA explained 53.3 % of the total variance, factor 1 (33 %) correlating the
communities of Diplopoda, Formicidae, Isopoda, Opilon, and Thysanoptera and factor 2 (20.3
%) correlating the communities of Scorpions, Hymenoptera, and Uropyge.
In the early rainy season, the 2-year-old control and secondary forest showed similar total soil
macrofauna densities of 379 ind.m-² and 388 ind.m-², respectively, while during the rainy season,
the variance in secondary forest decreased to 231 ind.m-². This is probably due to the low
subsoil density in the 2-year-old secondary forest (personal observation), which after the chopping
treatment got exposed to sun and rain. The 5-year-old secondary forest showed a higher internal
variation, and soil macrofauna density in control secondary forest was higher (311 ind.m-²) than
that of mulched secondary forest. Although the differently aged non-mulched secondary forest
showed higher soil-macrofauna densities than the secondary forest, the densities in the 5- and
10-year-old secondary forest were higher than that in the 2-year-old secondary forest during the
rainy season.
