Resumo: This study evaluated the soil fertility, biomass and microbial activity of the soil under forest cover of Eucalyptus grandis, Eucalyptus pilularis, Eucalyptus cloeziana and Corymbia maculata; Pinus Caribbean var. hondurensis, 40 years old, and a fragment of Semideciduous Forest, located on the campus of the Federal University of Lavras. In soil samples collected in the 0-5 cm layer were determined fertility parameters, basal respiration and microbial biomass carbon. The results showed that for the species E. grandis and E. cloeziana the carbon of biomass microbial content was higher than for any other ecosystem evaluated, and equal to those observed under native forest. In contrast, the ground under Pinus had the lowest microbiological indexes. Under C. maculata and E. pilularis the contents were intermediate for this parameter. The basal respiration of all ecosystems was equal. The fertility level was very low in all types of evaluated vegetation.

Em amostras de solo coletadas na camada de 0-5 cm foram determinados parâmetros de fertilidade, a respiração basal e o carbono de biomassa microbiana. Os resultados mostraram que as espécies E. grandis e E. cloeziana mantiveram teores de carbono de biomassa microbiana mais elevados dentre os ecossistemas avaliados e iguais àqueles observados sob a floresta nativa. Em contraste, o solo sob pinus apresentou os menores índices microbiológicos. Sob C. maculata e E. pilularis os teores foram intermediários para este parâmetro. A respiração basal de todos os ecossistemas foi igual. O nível de fertilidade foi extremanente baixo sob todos os tipos de cobertura vegetal avaliados.CERNE2016-06-062017-08-01T20:15:25Z2017-08-01T20:15:25Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttp://www.cerne.ufla.br/site/index.php/CERNE/article/view/1197BRAGA, R.
