Abstract

Granulometric parameters (mean diameter, graphic standard deviation, graphic assimetry and kurtosis) and morphological characteristics of a Entisol were studied in soil profiles ocurring in three different positions of a toposequence. The studied area is located in the Itirapina and Brotas municÍpalíties, State of São Paulo (Brazil). The granulometric homogeneity of the sand fraction was observed between horizons and profiles. Morphologically the profiles do not differ one to each other and usually show an A-C sequences of horizons and sometimes an incipient B horizon, identifiable by color.
