Resumo: This study was motivated by the scarcity of studies involving descriptions of edaphic horizons in the transition from savanna to forest. It aims at comparing the chemical features and the texture of savanna and forest soils in one ecotone, and at considering possible edaphic infl uences on vegetation. In areas pertaining to the Botanical Garden of Bauru, State of São Paulo, two-meter deep pits were opened in different parts of a seasonal semi-deciduous forest and of a forested savanna to directly collect soil samples in different horizons. The physicochemical analysis revealed high contents of different nutrients, e.g., Ca and Mg, and low contents of Al in the superfi cial horizons of the seasonal forest, which were classifi ed as eutrophic. Conversely, all the forested savanna horizons were considered as dystrophic. These edaphic features may be due to the different microenvironments of the studied phytocenoses.

Trincheiras abertas com profundidade de 2m, em diferentes pontos na floresta estacional semidecidual e savana florestada, em área pertencente ao Jardim Botânico de Bauru, estado de São Paulo, foram usadas para coleta de amostras de solo, diretamente nos diferentes horizontes. Os resultados das análises físico-químicas indicaram elevados teores para diferentes nutrientes, e.g., Ca e Mg, e baixos teores de Al em horizontes superficiais na floresta estacional, que foram classificados como eutróficos. Na savana florestada, ao contrário, todos os horizontes foram considerados distróficos. Essas diferenças edáficas tiveram origem, possivelmente, de microambientes distintos, existentes nas fitocenoses estudadas.Iheringia.
