説明

A simple method of pF measurement was developed by combining TDR-Tensiometer with TDR-Hygrometer. Using this method, we can measure the soil moisture characteristic curve over the wide range easily. This method was applied to the soil moisture characteristic curve of Toyoura sand. The experimental results were compared with those of the ordinary methods (e.g., suction and pressure plate methods), and its availability was discussed. As a result, the values measured by the TDR-Tensiometer were in good agreement with those of the ordinary methods, but the values measured by the TDR-Hygrometer were not satisfactory. Some problems to be overcome in the future were presented.
