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. (Soil Sci. Soc. Am. J. 68:1386-1393; Soil Sci. Soc. Am. J.  68:2000-2006).
