The objectives of this study were to evaluate the influence of three soil cover species Acacia auriculiformis, Mimosa caesalpiniifolia and Corymbia citriodora compared to pasture and natural secondary forest on soil chemical and microbial attributes. The field survival rate of the species reached over 70% and the development in height and diameter (DAP) was adequate. The survival rate of Mimosa caesalpiniifolia was the highest among the legume species, while the development of Acacia auriculiformis was the best, mainly between 27 […]

Although periodically flooded ecosystems represent 25% of the total Amazon area, they contribute to 75% of timber production. Both periodically flooded and upland ecosystems are greatly diverse in species belonging to Leguminosae family. Some of these species are currently exploited, but the economic potential of the vast majority has been overlooked. The knowledge of the plant growth characteristics of these species under nursery conditions is the first step to understand their biology and establish artificial woodlands in deforested areas. This […]
