Resumo: Crop rotation and cover crops may have direct and or indirect effects on soil physical properties. To study these effects,physical analyzes were performed on soil samples collected in the beginning of the eleventh year of conducting an experimentwith crop rotation systems, using as reference the soil kept continuously without vegetation (bare soil). The following variableswere analysed: saturated hydraulic conductivity and attributes related to aggregation and aggregate stability in undisturbedsamples collected in two layers, and soil density, penetration resistance and porosity in undisturbed samples collected in fourlayers. Simple correlations and regressions between chemical and physical soil attributes were determined. The crop rotationsystems had higher aggregate stability and volume of micropores and lower bulk density and total porosity in the superficiallayer, which is related to the higher amount of organic material added by crops. On the other hand, they did not alter thesaturated hydraulic conductivity, macroporosity and penetration resistance in all of the soil layers sampled.

Para estudar esses efeitos, foram realizadas análises fsicas em amostras de solo coletadas no início do décimo primeiro ano de condução de um experimento com sistemas de rotação de culturas, usando como testemunha o solo mantdo contnuamente sem vegetação. Foram determinadas a condutvidade hidráulica saturada e os atributos de agregação e de estabilidade de agregados em amostras coletadas com estrutura preservada em duas camadas; bem como densidade,resistência à penetração e porosidade do solo em amostras coletadas em quatro camadas. Também foram determinadas correlações e regressões simples entre atributos químicos e fsicos do solo. Os sistemas de rotação de cultura apresentam, na camada superfcial do solo, menor densidade e maior estabilidade de agregados, maior porosidade total e volume demicroporos do que a testemunha, o que está relacionado ao maior aporte de material orgânico. Por outro lado, não alteram a condutvidade hidráulica saturada, o volume de macroporos e a resistência à penetração do solo em todas as camadas amostradas.
