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.

Abstract. The use of microbial inoculants has become an effective alternative for increasing crop yields, reducing production costs, and improving environmental sustainability. Farmers are very interested in microbial inoculants involved in the solubilization of non-labile phosphorus due to the increasing demand for phosphate fertilizers and the scarcity of natural sources of this nutrient. Thus, the Brazilian Agricultural Research Corporation (Embrapa), in partnership with the Simbiose Company (Rio Grande do Sul, Brazil), has developed a commercial phosphate-solubilizing inoculant combining the Bacillus subtilis CNPMS2084 and Bacillus megaterium CNPMS119 strains. The present work evaluated the effect of different doses of this Bacillus strain inoculant in combination with phosphate fertilization on sugarcane crops in three experimental fields for two successive production seasons (plant cane and first ratoon). Vegetation indices (VIs) were calculated with the help of aerial images collected regularly during the phenological phases of vegetative growth and ripening and used in association with weather and yield data to develop a predictive model for the effect of the bioinoculant on the sugarcane crop. The results showed that the doses of 500 and 750 mL/ha of Bacillus strain inoculant applied in the planting furrow and during ratoon management were the most effective to increase tons of cane per hectare (TCH) and tons of sucrose per hectare (TSH) compared to treatments without inoculant application. These results agree with the forecast generated by the statistical model developed to predict the impact of the bioinoculant on the increase in sugarcane biomass. Afterward, the fitness of the model to estimate the effect of the Bacillus strain inoculant on the sugarcane yield was demonstrated when field data from commercial areas of sugarcane treated with the bioinoculant were compared to data from control fields without application, confirming the positive effect of the commercial Bacillus strain inoculant for sugarcane crops as well as the model´s effectiveness in handling and predicting yield from data obtained from commercial areas.
