dc.descriptionThe aim of this study was to micromorpholog ically analyze modifications in soil porosity due to the occurrence of erosive rainfall events. Thr ee types of soils, Typic Hapl udox, Typic Hapludult and Rhodic Kandiudalf, were analyzed to determine thei r total porosity and the distribution and number of pores. The soils were tilled with a heavy disk and leveling harrow to ensure homogeneity of surface conditions at the beginning of the trial period and to simulate cropping conditions. The soils were kept uncovered during the trial period, and rainfall events with intensities greater than 25 mm h -1 were recorded. The results showed that all of the soils presented crus t formation, influenced by the soil texture. NVef showed significant changes in total porosity, pore numbers and pore morphology, while LVAd and PVAd did not display marked modifications in these attributes.
