The Application of Heat of Wetting Measurements to Soil Research Problems

Abstract

The heat of wetting measurement has been introduced into soil science by E. A. Mitscherlich(1), who constructed for his investigations a rather complicated apparatus, consisting of an ice calorimeter which had been adapted for the special requirements of soil tests. Mitscherlich used the heat of wetting as a measurement of the heaviness of different soils, but soon found the technique too difficult, and later preferred the wellknown hygroscopicity determination which he had worked out in collaboration with H. Rodewald(2).
