ABSTRACT The objective of this work was to evaluate changes in the chemical attributes of an Inceptisol in two areas of sustainable management of the Caatinga Biome and a conventional tillage, compared with the native forest. The areas were managed in the following way: in areas under sustainable management, the Caatinga was thinned in a savanna system (1), and in the other area, the Caatinga was thinned in strips (2); the area under conventional tillage was burned, plowed and harrowed (3), and the native forest (4). The following chemical attributes were analyzed: pH, electrical conductivity, Ca2+, Mg2+, H + Al, P, Na+, K+ and soil organic matter (SOM), calculating CEC and base saturation. The treatments were evaluated using multivariate analysis, at different depths up to 0.52 m. In the Caatinga areas thinned in a savanna system and in strips, the greater availability of exchangeable bases and SOM occurs close to the depth of 0.20 m and, in the area with traditional agriculture, it is limited to 0.10 m. In the area thinned in a savanna system, sodium showed a negative correlation with the other elements
