The intensive use of natural resources for food production has ruptured the sustainability of agro-ecosystems. In this context, this study aimed to quantify chemical attributes of Oxisol under five management systems: 1 = conventional tillage (CT); 2 = no-tillage system with millet (NT + M); 3 = crop–livestock integration system with soybean (CL + S); 4 = CL with pasture (CL + P); and 5 = native forest (NF). The following soil depths were studied: 0.00–0.05, 0.05–0.10, and 0.10–0.20 m; and the following traits were quantified: total organic carbon (TOC), soil acidity (pH), soil potential acidity (H + Al) and soil fertility (Ca, Mg, P and K). All treatments modified soil chemical attributes in comparison to NF (p |
