Abstract

This paper explains the need for an alternative conceptual framework for conducting macroscale soil geographic research. A top-down approach to the classic state factor paradigm is described and illustrated by revisiting the idea of soil zonality to investigate the relationship between climate and soil character across the contiguous United States. Data from 10,661 sample points were analyzed using geographically weighted regression (GWR) models to describe the geography of the relationship between A-horizon soil properties and climate. In addition, macroscale soil property surfaces were interpolated from measured point samples visually to assess the validity of the zonal soil concepts. Results suggest many interesting relationships between climate and surface soil character
