Though much has been done to understand proximally-sensed bulk apparent electrical conductivity (ECa) in agricultural soils, many of the soil properties identified to be mappable using these techniques, such as salinity and clay content, are not expe

Gypseous (> 40% gypsum) and gypsiferous (1 to 40% gypsum) soils are estimated to comprise from 100 million to 200 million ha globally including over 1 million ha in the U.S. More intensive land use on these soils has resulted in greater demand for in

Ultramafic-derived soils impact agricultural productivity and environmental quality. The mineralogy of soils developed from ultramafic parent materials of the Great Dyke, Zimbabwe, at Mpinga (~800 mm mean annual rainfall) and Bannockburn (~500 mm) we

Middle Archaic earthen mound complexes in the lower Mississippi valley are remote antecedents of the famous but much younger Poverty Point earthworks. Watson Brake is the largest and most complex of these early mound sites. Very extensive coring and

Many municipal water supplies in southeast Texas have a relatively high level of Na+ and a low total of dissolved solids. Most soils of this area are dominated by smectitic clays that respond to wetting by swelling, especially when wetted with high N

Utilization of existing soil survey databases for characterizing water flow and solute transport in field soils has practical value. However, the lack of a proper means for quantifying soil morphology limits the incorporation of soil structural infor

Pedotransfer functions (PTFs) have gained recognition in recent years as an approach to translate simple soil characteristics found in soil surveys into more complicated model input parameters. However, existing pedotransfer functions have not yet in
