Textural density was determined for samples receiving different treatments of dynamic compaction. The samples were obtained from a coarse textural soil submitted to three different agricultural managements. Increases in the values of the textural densities were obtained for all samples including these representing the virgin soil.Se analizaron las modificaciones de la estructura de un suelo de textura gruesa con variado manejo y sometido a una compactación dinámica (Proctor) por medio del análisis de sus sistemas de porosidad y de la distribución por tamaño de poros.
