Research Highlights
Application of fractal analysis to quantify soil
structure from x-ray computed tomography (CT) scan
images. Estimation of fractal lacunarity using CT
data. Method have proved useful as a quantitative tool
to describe soil structure (Soil Sci. Soc. Am. J.
60:1718-1724; Water Resour. Res. 30:691-700.
Application of a fractal-like topological method called
Multiple Resolution Blankets (MRB) to quantify soil
structure using fuzzy logic to predict soil hydraulic
conductivity using CT scan data (Intelligent
Engineering Systems Through Artificial Neural
Networks 11:307-312).
Development of methods to non-destructively
measure soil bulk density and water content in
soils with CT. This work was the first to
accurately explain x-ray attenuation coefficients
using soil mineral concentrations (Soil Sci. Soc.
Am. J. 52:35-40; Irrig. Sci. 10:63-71).
Development a technique for using CT for
measurement of soil bio-pores (Geoderma 46:13-
29; Geoderma 53:329-340).
Research on in situ soil hydraulic conductivity
of a benchmark Missouri soil (Soil Sci. Soc.
Am. J. 2002 66:1596-1602). Application of an
inverse method to determine soil porosity and
hydraulic conductivity distributions on a small
core using CT-measured breakthrough
experiments. (Geol. Soc. London Spec. Pub.
215:135-149).
Research to reduce soil erosion, including use of
stiff-stemmed warm season grass hedges. This
work has identified a new, economical method to
remove nitrogen, phosphorous from runoff.
Ongoing research suggests that these buffers can
also decrease pesticide transport in surface runoff.
