ABSTRACT The Middle São Francisco River valley is a vast territorial area with marked seasonal change and diversity of lithology, landscapes, soil, and vegetation. However, the relationships between soil characteristics and plant communities are poorly known. In this study, we show the relationships between key soil properties that determine the establishment of savanna-steppe, wooded savanna-steppe, savanna, semideciduous forest, and deciduous forest in this region through analysis of 166 soil profiles. In general, savanna soils are much more leached, Al-saturated, and […]

One of the factors affecting the distribution of native vegetation is soil formation. Therefore, soils under native vegetation can be highly informative with regard to a region and the original soil fertility, as records of conditions found before agricultural reclamation (agrosilvopasture). The purpose of this study was to assess soil fertility and texture under native vegetation fragments sampled during the Forest Survey of the State of Minas Gerais, Brazil. In general, the variability in all soil properties was high, except […]
