Users are provided only one set of soil properties. We consider the combination of use-invariant and use-dependent databases to produce composite recorh. The use-invariant data is determined by soil origin and genesis and is at most only slightly subject to change with use. The use-dependent data is readily subject to change by use. Near-surface properties are particularly subject to change with use. Each use-invariant property is assigned a surficial exclusion zone within which the property is considered use-dependent and hence the standard interpretive record is not applicable. Both use-dependent and use-invariant properties are placed in one of five classes. Numerical rankings for quality evaluation are obtained by combining the placements for the several properties concerned. ER -
