Title: Calibration and Application of Self-Made TDR Probe
Abstract: TDR probe was made according the work principle of TDR and calibrated in the laboratory.The result showed that the relationship between the square root value of dielectric constant of soil and soil water content in volumetric basis can be well described by linear equations of which the correlation coefficient are greater than 0.995.A comparison of measuring soil water content with self-made TDR probe and neutron probe was made in field.The result showed average absolute error is 0.17% and average relative error is 8.58%.It is concluded that self-made TDR probe can be used in the other area of Loess Plateau.
