Abstract

The area under study is located at Maloca do Flechal, in the Uiramutã County, northeastern Roraima. Soil samples were collected along an east-west soil catena following the outcrops of the main mafic body, observing geomorphological aspects, as well as native land use and applied management, selecting areas with natural pasture and subsistence agriculture (slash-and-burn) for more than 20 years by local Indians. The samples were submitted to physical and chemical analysis. Results and discussion about their classification and physical properties, mineralogical soil composition, chemical characterization
