Resumo: | ABSTRACT The Cerrado is a vegetation complex with a wide variety of phytophysiognomies, and sustainable management is essential for maintaining biodiversity. Morphopedology is a tool that can assist in developing plans for control of soil and land use, especially in evaluating the potential of soil erosion processes. This technique allows landscape units considered “homogeneous” to be distinguished, as a result of interaction between physiographic conditions. The aim of this study was to evaluate potential for erosion in São Miguel do Araguaia, state of Goiás, Brazil, through definition of morphopedological compartments (MPC), on the assumption that soil use has increased erosion. Landscape units were identified through use of geology overlay, hypsometry, slope, geomorphology, soil, and land use. The map information on a 1:100,000 scale was refined, the base of which was available in the Geographic Information System of Goiás. The morphopedological approach enabled identification of five MPC. Predominant soil classes in São Miguel do Araguaia (with matching categories) are Latossolos Vermelho-Amarelo Distróficos (Xanthic Hapludox), Plintossolos Pétricos Concrecionários (Petronodic Haplargids), Plintossolos Háplicos Distróficos (Plinthic Haplaquox), Gleissolos Háplicos Tb Distróficos (Typic Endoaquents), and Neossolos Quartzarênicos Órticos (Typic Quartzipsamments). Generally, every class of soil has some type of limitation that may cause erosion to different degrees. The most dissected areas are associated with lateritic covers, which suggests the importance of these features on topographical formation. The results of analysis of erosion susceptibility and linear erosion potential suggest low risk of erosion, even considering human activities, especially cattle ranching.
