Abstract:

The spatial variability of soil hydraulic properties that govern infiltration were investigated at a pristine site and an agricultural site in the Konza Prairie Research Area of east-central Kansas. Soil hydraulic properties studied were saturated hydraulic conductivity, matrix flux potential, soil sorptivity, and pore-size distribution parameter. Spatial variability was assessed through semivariograms that were constructed based on 37 measurements at each site using the Guelph Permeameter. The spatial structure of infiltration properties at the two sites exhibited pseudo periodicity and a hole-effect variogram model was used. The range of the infiltration properties was in the order of 2m.
