Brazil is the world’s biggest meat exporter; more than 40% of beef production takes place in the Brazilian savanna pastures. The research site was located in Southeastern Brazil (20º18’16.71”S; 44º55’28.57” W) and had 35.3 ha of silvopasture (SP) with signal grass (Urochloa brizantha) and native legume tree, Pterodon emarginatus,with a density of 156 trees ha^-1 established more than 30 years as cattle pasture never fertilized. The control (CT) had 26.5 ha traditional signal grass pasture. Soil collection profiles were made randomly at both areas at 0-10, 10-20, 20-40, 40-100 and 100-140 cm deep, in order to study the chemical attributes and the influence of a stabilized silvopasture. Calcium (Ca⁺²) was higher (P<0.05) in the CT, compared to SP area at 0-10, 10-20cm profiles, but no difference was found in other layers. Inside SP, Ca⁺² in 0-10 cm was higher (P<0.05) than 10-20 and 100-140cm, while intermediate values where found at 20-100 cm profiles. Variables P M1, K⁺, S-SO₄⁼, Zn, B and Sum of Bases (SB) did not show differences between systems (P>0.05), but Organic Carbon (OC), Cu and Fe were higher at SP, while Water pH had superior values in the CT(P<0.05). OC, Fe e P showed decreasing differences (P<0.05) with increasing of depth for both systems. Al, Cu and B were higher (P<0.05) down to 40 cm deep and reduced from this layer. Levels of Zn and SB were higher (P<0.05) at 0-10cm and kept the same values in other depths. Sulfur was higher in 0-10cm in comparison to100-140cm depth (P<0.05), but the other profiles were intermediate. Non-fertilized silvopastoral system with native legume trees adapted to poor acid soil, had higher carbon content than traditional pasture, however, there was extraction of most of the nutrients.
