| 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... |
