The objective of this study was to evaluate the physico-hydric soil properties under different management systems in comparison with the native Cerrado, in Santo Antônio de Goiás, Goiás State, in areas cultivated since 1993. The evaluated systems in the depths of 0 - 0.10 and 0.10 - 0.20 m were: system S1 (soybean/bean/rice/pearl millet /bean), system S2 (soybean/pearl millet/corn), system S3 (corn + Brachiaria brizantha in integrated crop-livestock system) and system S4 (native cerrado). To compare the results obtained in the several soil management systems, the interval of confidence was used, at a probability level of 5%. The use of area under Brachiaria brizantha pasture for animal grazing caused compaction of the soil in the surface layer, verified through the reduction of the macroporosity, and increase of the microporosity and soil bulk density.
