A Comparison of Soil Moisture Measurements using Different Commercial Sensors

Soil moisture and temperature measurements were made using the Vitel Hydra probe and the PR1/6 sensor from Dynamax. Measurements were made a similar levels and additional measurements were made around the study area using additional access tubes for the dynamax probes. Volumetric water content was computed from each of the sensor types using the stated procedure and set of equations for each sensor. Additional comparisons of the dielectric constants that were determined from each of the sensors at various soil depths will be presented.
