The dielectric calibration of capacitance probes for soil hydrology using an oscillation frequency response model
soil hydrology oscillation frequency response model
2009/5/27
Capacitance probes are a fast, safe and relatively inexpensive means of measuring the relative permittivity of soils, which can then be used to estimate soil water content. Initial experiments with ca...
Practical considerations on the use of down-sized time-domain reflectometry (TDR) probes
TDR probepulse travel time dielectric constant electrical conductivity
2009/3/17
Nine time-domain reflectometry (TDR) probes, 2 to 10 cm long, were evaluated by comparing their measurement accuracy of TDR-pulse travel time in a sand and sandy loam soil, and electrical conductivity...
