Was studied an area located in the transition region between the Agreste and the Sertão regions of Pernambuco, owned by private property named Fazenda Arizona,in the municipality of Sertânia - PE. Was initially performed the georeferencing based on Law 10267/2001 of the INCRA, using for such a satellite tracking in GPS system, DL4 Plus model made by Novatel. Based on the topographical map produced, was conducted a soil survey, being the whole area surveyed using the auger hole and making annotations related to the slope, erosion, drainage, vegetation and relief. At a later stage were carried out trenching, for description of profiles and collecting samples of soil horizons, followed by physical and chemical analysis, aiming to classification and soil mapping based on the SIBCS (Brazilian System of Soil Classification). In addition to the soil map of Arizona farm, were also obtained the slope map and the map of cross-validation between the soil and slope classes. It was found that the main difficulties for the georeferencing were the deadline, the misinformation on the part of landowners and the bureaucracy in the official registries. Were found soils belonging to Neossolos, Cambisols, Luvisols,Alfisols and Oxisols classes, being the representant of the Oxisols, the best one suited for agricultural use. The Entisols are the main components, occupying about 61.36% of the total area. The predominant types of relief were the smooth and wavy terrain. From the point of view of environmental requirements, the areas for the permanent preservation occupy about 24,41% of the total. The fragility of the environment is increased as a function of shallow soils and high surface stoniness.
