Heat of Wetting of Soils

Abstract

Many important soil processes such as base exchange capacity, plant food availability and moisture holding capacity, are influenced by the amount of surface per unit mass of soil. For this reason, measurements related to this soil characteristic may be used in connection with many soil problems. This article is concerned with the description of a method of measuring the relative surface area of soils with apparatus suited for student use. It consists in measuring the heat energy liberated by a dry soil which is wetted by water at the same temperature.
