Soil quality and pedology are similar in their melding of concepts and disciplines and their reliance on the model of soil formation described by Jenny in 1980. They differ in spatial and temporal scales and in the organisms concerned. In this regard, soil quality can be considered part of the science of pedology. Significant differences in selected near-surface soil properties and subsequent interpretations as influenced by land use are illustrative of the need to collect data reflecting use-dependent or dynamic soil properties. Inherent or use-invariant properties dictate the limits to which dynamic properties range. As pedologists begin to explore these relationships, a dynamic soil properties database should be developed as a companion to the database of use-invariant properties used currently for classification, mapping, and interpretation.
