  abstract = {{S}oil structure plays an important role in water retention, infiltration capacity, porosity, and penetration resistance. {T}he aim of this study was to evaluate the unsaturated hydraulic conductivity and physical properties of {O}xisol soils (bulk density and macro-, micro-, and total porosity) in the structures identified using the profil cultural method in areas under two different management practices (perennial pasture and sugarcane). {T}hree pits were dug in each plot to find out how homogeneous morphological structural units ({HMSU}) were organized in the soil. {N}ext, unsaturated hydraulic conductivity ({K}i) was measured in situ inside each {HMSU} using a triple-ring infiltrometer at multiple suction. {S}ix samples were collected (two samples for each kind of structural organization in each pit) to determine soil bulk density, total porosity, and macro- and microporosity. {E}ach management practice resulted in a distribution of structures in the soil profile. {T}he behavior of morphologically similar clods was the same, regardless of the physical manipulation of the soil. {T}he distribution of structures based on the management practice determines specific hydraulic conductivities in the soil profile.},
