The Rod Spacer allows for accurate soil moisture measurements at 0.5" (1.3 cm) or 1" (2.5 cm) depths when used in conjunction with a standard set of 1.5" (3.81cm) rods. Measuring and understanding ...

Accuracy of Soil Moisture Meter in Saline SoilsFigure 1. TDR sensors accurately estimate moisture in a USGA sand at salinity levels of ECe < 5 dS m -1, but special calibration is needed when soil ECe ...

Time Domain Reflectometry (TDR) has emerged as an invaluable tool in soil science, offering precise quantification of moisture content and the electromagnetic characterisation of soils.
