Abstract
The expansion of agriculture in the cerrado is adversely affecting the physical properties of the soil. Being compounded by inappropriate management and inadequate soil, where they are not taken into account their physical characteristics to implement the cropping system. The objective of this work to observe the impact of agriculture on soils of southwest of Goias S tate , showing the stages of degradation of soils under different anthropogenic use. The areas studied are located in Goiás Federal Institute - Campus Rio Verde - GO. The soil in the area was classified as dystrophic Oxisol. Managing four different areas were evaluated: cultivation of sugarcane (3 year); conventional planting annual crops (soya/corn); ILPF (3 years) and Cerrado area permanent reserve. We determined the rate of infiltration curves (VI), infiltration rate (VIB), hydraulic conductivity (Kfs), soil density (Ds), macroporosity (Macro) and microporosity (Micro), the total porosity (TP), density particles (Dp). The system managed sugarcane obtained with favorable soil conditions mainly to the Ds, Dp, PT and Macro 0 to 20 cm and 20 to 40 cm. The Cerrado to keep you characterize their soil showed the highest VIB (56.89 cm h -1 ). In the medium term, intensive tillage system was more correlated with soil infiltration capacity than the compaction process itself.
