The oxidation of atmospheric CH4 in upland soils is mostly mediated by uncultivated groups of microorganisms that have been identified solely by molecular markers, such as the sequence of the pmoA gene encoding the -subunit of the particulate methane monooxygenase enzyme. The objective of this work was to compare the activity and diversity of methanotrophs in Amazonian Dark Earth soil (ADE, Hortic Anthrosol) and their adjacent non-anthropic soil. |

The increase in the feedlot pig production has generated high amounts of manure, being in
general applied in agricultural areas as organic fertilizer. However, its excessive or continual
use can cause negative environmental impacts, such as unbalanced relations in soil chemical,
physical and biological properties, water pollution, losses in crop yields, and decrease in the
quality of farming products. The objective of this study was to assess the effects of crescent
doses of pig slurry on physical and structural soil properties, and their relation with abundance
and diversity of soil macrofauna. The experiment is carried out in Campos Novos, SC, southern
Brazil, since November 2001, on a red distroferric latosol. The treatments are: 1) Control (0); 2)
Mineral fertilization (MF) 3) organomineral fertilization (OM); 4) 50 m3 ha-1 of pig slurry (50); 5)
100 m3 ha-1 of pig slurry (100); and 6) 200 m3 ha-1 of pig slurry (200). The experimental design
was completely random blocks, with four replicates. The crop system was the succession of
maize (Zea mays) and black oat (Avena stringosa), under no tillage soil management. Soil
samples for physical analyses were collected in January 2006, in the layers of 0-5; 5-10; 10-20
cm depth. The analyzed properties were organic carbon, aggregate stability, soil density, macro,
micro and total porosity. Soil macrofauna was collected in the layer of 0-10 cm, in May and
September 2005, and in January 2006. The use of pig slurry in rates of 50 and 100 m3 ha-1
decreased soil aggregate stability, in relation to the control treatment. However, this soil can be
considered with a good structure, with mean geometric diameter values from 5.9 a 6.3 mm. The
other physical properties related to porosity and soil density, as well as, organic carbon contents
had no effect of pig slurry application. There was no correlation between soil physical properties
and abundance and diversity of soil macrofauna. The treatment MF had the lowest values for
ecological index, related to its low macrofauna diversity. The principal component analysis
separated the treatments OM and 100 from the others, according to the considered axis. MenosThe increase in the feedlot pig production has generated high amounts of manure, being in
