The work had as objective to evaluate the influence of the scarification on physical attributes of the soil and on the distribution of the root system of Rangpur lemon budded with the ‘Pêra’ orange. Four trenches were digged for each treatment (inter-row scarified and inter-row not scarified) The distribution of the roots in the row and inter-row were evaluated down to 1.0 m depth with the SIARCS 3.0 software (Sistema Integrado de Análise de Raízes e Cobertura do Solo). The total porosity and soil bulk density were evaluated in three depths (0.000-0.125; 0.125-0.250 and 0.25-0.375 m) in three sites: row, inter-row and limit of the tree canopy in the inter-row. Three years after scarification there were no differences among treatments for soil total porosity and bulk density on inter-rows and for the amount of roots of all depths and sites.
