Calibrating Time Domain Reflectometers for Soil Moisture Measurements in Sandy Soils

Campbell Scientific CS616 Water Content Reflectometer.

The UF/IFAS Plant Science Research and Education Unit (PSREU) in Citra, FL developed an in-laboratory calibration protocol for CS616 TDR sensors for sandy soils, which are typical of north central Florida. This new 7-page fact sheet discusses the reflectometer, field site, calibration protocol, and calibration coefficients.
