The aim of the present study was to describe some hydro-physical attributes, the relationship between them, and their spatial variability.
The research was carried out in Puerto Lopez (Meta, Colombia), in a Typic Haplustox.
The sampling was done with a mesh of 64 points, with perpendicular distances of 52 m by 45 m between points.
The attributes studied were bulk density, volumetric moisture, sorptivity, saturated hydraulic conductivity, and the sand, silt, and clay contents.
The data were analyzed by descriptive statistics, multivaried analysis, and geostatistics. The saturated hydraulic conductivity was the only attribute that did not show spatial dependence.
The bulk density, volumetri...
