Fig. 7. Scatter function obtained in saturated Millville silt loam at two different salinity levels using a 3-cm long three-wire probe. Resonant frequency analysis (RFA) of the 48 dS m–1 scatter function using the intersection of two lines drawn through the rising portion of the scatter function data in the first trough yields a permittivity, 
x, of 30.2 following Eq. [10]. This is comparable with the static permittivity (s = 29.9) obtained from fitting the Debye (1929) model to this data.
