Soil biota is the major responsable for the regulation of various processes such as decomposition,
mineralization and nurient cycling wich affect the plant growth and the production maintenance
in long-term (LAVELLE, 1997). The aim of this study was to evaluate the influence of planting
legume trees as an estrategy for land reclamation above soil macrofauna. The study area
includes a slope, at the Municipality of Valença, Rio de Janeiro state ? Brazil, originally in the
Atlantic Forest Biome, but under a secondary sucession process. In the experimental area it
was introduced seven tree fixing nitrogen legumes species in four proportions of the total number
of trees planted: 0% (0L), 25% (25L), 50% (50L) and 75% (75L). Other samples were taken in
a secondary forest, and in two areas of pasture, an abandoned pasture (Pasture B), with
spontaneous vegetation, grass and some bushes, and other pasture that is regularly grazed by
animals, with predominance of Brachiaria grass ( Pasture A). The sampling occurred at the end
of the dry season, using the method TSBF (ANDERSON & INGRAM, 1993) at depths of 0-10
cm, 10-20 cm and 20-30 cm, and the litter layer. Treatment 50L had the lowest total fauna groups
richness and at the same time that showed the highest macrofauna density, mainly because of
the Formicidae dominance. However, in the treatments 25L and 75L it was observed the lowest
abundance and in contrast the greatest groups richness what suggests that they contribute to
the better soil fauna colonization. Analyzing the macrofauna vertical distribution, in the almost all
areas the largest abundance of organisms occurred in the soil superficial layer (0-10 cm),
exception for 25L and 75L treatments. The soil fauna colonization of this layer raised 70% in
Pastures A and B. This similarity observed in vertical distribuition between the forest and pastures,
suggests an influence of the sampling period, that took place after the dry season, when the
vegetation was very affected. The number of individuals present in the 10-20 cm depth proved
to be roughly similar for all treatments, while the greatest abundance in 20-30 cm was observed
in 75L treatment. The soil fauna diversity was similar among treatments, with the predominance
of the family Formicidae, followed by Isoptera, characterizing the intense colonization of social
insects in these systems. MenosSoil biota is the major responsable for the regulation of various processes such as decomposition,

Atualmente o mal-do-Panamá é considerado uma das doenças mais destrutivas e limitantes da bananicultura, tendo como agente causal o Fusarium oxysporum f. sp. cubense (Foc), um fungo habitante do solo, cuja sobrevivência na forma de clamidósporos e na forma saprofítica, proporcionam estabelecimento por mais de 30 anos, mesmo na ausência do hospedeiro. Até o presente momento a principal forma de manejo da doença é a utilização de variedades resistentes. |
