Alterations to the environment cause changes in the species number as well as in the species
composition of soil organisms. The conversion of forest or pasture into farmland implies a drastic
environmental change. Forest conversion to agriculture removes extremely diverse, complex
and stable multistructured ecological systems, directing ecological succession to the first stages
of immaturity, simplification and instability. The aim of this research was to estimate the soil
macro-fauna community of differently managed soil systems in small farms of the Tarumã-Mirim
rural settlement. Thirty km north of Manaus, Amazonas, farmers have participated in sampling of
the soil monoliths and in sorting of the invertebrate during the rainy season (March and April) in
2007. To study the communities structure of the macro-fauna in systems managed by small
farmers, five areas under distinct soil management systems were sampled: monoculture, poly
culture 1, poly culture 2, agroforestry system (AF) and primary forest. In each area five 50x50x20cm
monoliths were collected. The highest fauna biomass was found in the poly culture 1, totaling
157.8 g.m-². The predominant groups were Hemiptera (89.5 g.m-²), because a nest containing
various individuals was sampled, and Oligochaeta (56.2 g.m-²). The forest showed the lowest
biomass (26.3 g.m-²), consisting mostly of Oligochaeta (22.6 g.m-²). The agroforestry system
showed the second highest biomass, with a total of 108.5 g.m-², consisting of 67.7 g.m-² of
Oligochaeta, 19.6 g.m-² of Isopoda and 12.5 g.m-² of Formicidae. The agroforestry system was
the managed system with the highest density, totaling 6924 ind.m-², of which 3096 ind.m-² were
Isopoda, 1528 ind.m-² Oligochaeta and 724 ind.m-² Isoptera. The area with the lowest density
was the forest, with a total of 784 ind.m-², mainly composed of Isoptera (368 ind.m-²) and
Oligochaeta (192 ind.m-²). The high density in the AF is principally due to the large variety of fruit
bearing species that make the soil appropriate for different taxonomic groups, thus leading to
their colonization. By way of contrast, the primary forest showed the lowest biomasses and
densities, which indicates that plant species diversity within a managed system is very important
for a better macro-fauna colonization and diversity. MenosAlterations to the environment cause changes in the species number as well as in the species
