Abstract
Computed tomography (CT) is a promising tool that may help provide measurements needed to obtain finer resolution in soil-water content and bulk density for water uptake studies or detailed investigation of root-soil interactions. A need exists for a unified method to accurately predict soil bulk density and water content using output from CT. Research was conducted on soil collected from the A horizon of Mexico silt loam (Udollic Ochraqualfs) and the B2t horizon of Crider silt loam (Typic Paleudalfs) to evaluate the relationship between linear attenuation coefficients and volume fraction of soil solids and water. Results from this study indicate that it may be possible to develop a universal relationship for computed tomography data vs. soil bulk density and water content.
