It is very important to measure the water content and electric conductivity in soil for monitoring the environment of agricultural land continuously. TDR (Time Domain Reflectometry)method plays a key role on the measurement of water content and electric conductivity in soils recently. Some calibrations are needed to measure them accurately. The objective of this study was to investigate preliminaly the corrections of TDR probe, the probe constant for electric conductivity, and the dependence of water pemittivity on temperature as TDR calibrations. The results showed the importance for the corrections of TDR probe and the reasonable value of probe constant.The TDR system used in this study could measure the dependence of water pemittivity on temperature.
