Laboratory‐constructed and commercial salinity sensors were evaluated for stability of calibration and accuracy of measurement of soil salinity. Of the commercial sensors 85% were stable and performed satisfactorily for at least 1.5 years with an estimated accuracy of ± 0.6 mmho cm ‐1 . Laboratory‐constructed sensors were accurate to ± 1 mmho cm ‐1 . Commercial sensors were used to monitor soil salinity in a field in the Imperial Valley, demonstrating their value for salinity control. The salinity data revealed differences in water infiltration caused by surface topography and by the disturbance of soil during the installation of the sensor.
