Abstract
The Hilhorst (2000) model was able to convert sb to pore water electrical conductivity (sp) under laboratory conditions by using the linear relationship between the soil dielectric constant (eb) and bulk electrical conductivity (sb). In the present study, applying the linear relationship eb- sb to data obtained from field capacitance sensors resulted in strong positive autocorrelations between the residuals of that regression. We were able to derive an accurate offset of the relationship eb-sb a...
