Data variability was investigated in southern Italy by collecting runoff and soil loss from four universal soil\u2010loss equation (USLE) plots of 176 m<jats:sup>2<\/jats:sup>, 20 \u2018large\u2019 microplots (0\u00b716 m<jats:sup>2<\/jats:sup>) and 40 \u2018small\u2019 microplots (0\u00b704 m<jats:sup>2<\/jats:sup>). For the four most erosive events (event erosivity index, <jats:italic>R<\/jats:italic><jats:sub>e<\/jats:sub> \u2265 139 MJ mm ha<jats:sup>\u22121<\/jats:sup> h<jats:sup>\u22121<\/jats:sup>), mean soil loss from the USLE plots was significantly correlated with <jats:italic>R<\/jats:italic><jats:sub>e<\/jats:sub>. Variability of soil loss measurements from microplots was five to ten times greater than that of runoff measurements. Doubling the linear size of the microplots reduced mean runoff and soil loss measurements by a factor of 2\u00b76\u20132\u00b78 and increased data variability. Using sieved soil instead of natural soil increased runoff and soil loss by a factor of 1\u00b73\u20131\u00b75. Interrill erosion was a minor part (0\u00b71\u20137\u00b71%) of rill plus interrill erosion. The developed analysis showed that the USLE scheme was usable to predict mean soil loss at plot scale in Mediterranean areas. A microplot of 0\u00b704 m<jats:sup>2<\/jats:sup> could be used in practice to obtain field measurements of interrill soil erodibility in areas having steep slopes.
