Accuracy of soil moisture measurement by tdr technique (original) (raw)

The research investigates the accuracy of soil moisture measurements using the Time Domain Reflectometry (TDR) technique. This method is distinguished by its simplicity and non-destructive nature, relying on the correlation between soil moisture and dielectric constant. By comparing TDR results to reference values obtained through thermogravimetric methods, the study identifies potential sources of error, including hardware limitations and installation practices. Statistical analyses reveal insights into the reliability of TDR measurements across various soil conditions, ultimately emphasizing the importance of careful probe handling and data interpretation.
