Frequency dispersion of the real part, ε’, of the complex dielectric constant and the loss<br />
angle, δ, for the electrolyte for its various electrical conductivities, EC w<br />
The t<strong>im</strong>e-domain reflectometry as applied to the measurement of water<br />
content and salinity of porous materials <strong>im</strong>plements the property described above.<br />
3.4.2. Summary<br />
1. The lower electric conductivity of the electrolyte present in the soil, the lower<br />
is the lower frequency l<strong>im</strong>it, where the electrolyte behaves as pure water<br />
(dielectric, insulator), which enables the dielectric measurement of soil water<br />
content without the influence if its electric conductivity.<br />
2. If the electrical conductivity of the soil electrolyte does not exceed the value of<br />
1 [Sm -1 ], using the sufficiently high, but not higher than 10 10 Hz, frequency of<br />
the applied electric field, the ion conduction is dominated by orientation<br />
polarization of soil water particles.<br />
