The excessive animal trampling, together with the lack of conservation practices and adequate soil becomes compacted this, having a significant increase in density, caused by loads or pressures applied in this soil. The Tocantins state is characterized by livestock, particularly cattle, however, there are producers who create small animals such as ovinocaprinos. In literature there are few reports on the effect of trampling on the physical characteristics of an gleysol. This study aimed to evaluate the effect of two systems for livestock, Cattle and ovinocaprino on the physical attributes of an gleysol, located in the southern state of Tocantins. For it was rated the macro and micro-porosity, density and penetration resistance of both systems, separated by compartments. As a result there was a significant difference for the variable density, macro-and micro-porosity and mechanical strength, and it varied depending on the depth of the soil profile.
