Abstract

In the Southwestern Brazilian Amazon, a detailed study on the pedological cover of a representative toposequence for the region, characterized by lowered plateaus with topographic depressions, was carried out. The results indicated that pedogenic processes can be considered to be responsible for topographic smoothing and changes of the natural landscape. The main factor involved in this transformation process represents the upwards expansion of hydromorphic soil conditions from the topographic depressions developed in lower parts of the plateaus. This process includes internal transformations and degradations of the soil matrix leading to changes in soil structure, chemical composition and, diminishment of the original soil volume. (AU)
