Thermodynamics of soil moisture.

Abstract

The various equations used by several authors to express the partial molar free energy of soil moisture as a function of certain parameters were compared with a "parent" equation derived in this paper; certain basic differences of approach apparently lead to results which are identical only under certain conditions; from the parent equation, equations with practical applicability are derived. The methods available for the experimental determination of the partial molar free energy of soil moisture are reviewed with special reference to the assumptions underlying the application of the freezing-point depression of soil moisture.
