Soil was collected from five sampling points considering the distances from the tree lines. Undisturbed samples were collected from the 0.00?0.10 and 0.10?0.20-m layers in order to assess porosity, density, soil penetration resistance, soil water retention curve, and the "S" index. The forest arrangement based on three paricá lines promoted better soil physical conditions than the system using single lines. The main changes were recorded in the 0.10?0.20-m layer, with increased microporosity and decreased cryptoporosity and resistance to penetration. The arrangements using single and double paricá lines result in higher volume of available water and greater soil compaction.  aÁgua do Solo  aOchroma Pyramidale  aCurva de retenção  aICLF  aPhysical quality of the soil  aQualidade física do solo  aRetention curve  aWater in the soil1 aFREDDI, O. da S.1 aLANGE, A.1 aWRUCK, F.
