T lack of a method for following the moisture changes in the soil over a wide range of moisture contents has seriously handicapped soil and plant investigators in their efforts to evaluate correctly the results of experiments. Because of the seriousness of this need, an investigation was undertaken to find, if possible, a method of measuring moisture that would be simple in operation and would also, give accurate results. Preliminary work, which has been previously reported, pointed out that heat conductivity can be used as an index of soil moisture since the conductivity of a soil increases with its moisture content. Moreover, changing salt concentrations in the soil solution do not affect the results.
