The work was performed in agricultural properties, located on the hydrographic sub-basins of Santa Cruz and Água Limpa streams, belonging to the Rio Grande basin, Lavras, MG, with the aim of evaluating and relating soil physical attributes with pastures productivity. No differences were observed among bulk density, total porosity, micro and macro-porosity values in soils under different pastures, as well as under different soil samples depths. The animal trampling on these pastures, considering the amount of animals observed in the area and the continuous system of pasture management, did not translate to higher values of bulk density, at 0-10cm depth, and at the subsurface. Through canonical correlation one verified that pastures productivity showed association in its sensibility related to soils physical attributes.
