The Araripe Plateau in the tropic semi-arid region is characterized by great environmental diversity. The Araripe National Forest and several forest management units (FMU) are located in this area with mostly red-yellow Oxisols. The goal of this study was to identify a basic indicator that could represent a set of physical, chemical and biological properties of soils of the Plateau. Multivariate analysis was used to indicate changes in soil properties of a FMU. Soil samples were analyzed in triplicate (0-20 […]

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 […]
