Hilhorst 2000
Webcalibration. Recently, Hilhorst (2000) presented a theoretical model describing a linear relationship between bulk electrical conductivity, σa, and Ka in moist soil. Hilhorst found that, using this linear relationship, measurements of σp could be made in a wide range of soil types without soil-specific calibration.
