Time Domain Reflectometry (TDR) Soil Moisture Sensor
Calibration of time domain reflectometry for forest soil humus layers
... Time domain reflectometry (TDR) has become a widely used method for determining the volumetric water content of soils. However, due to the differences in bulk density and surface area, the relationship ...
