VII.—The Relation of the Soil Colloids to the Thermal Conductivity of the Soil
Published online by Cambridge University Press: 15 September 2014
Extract
Early investigators regarded the soil as an inert framework of soil grains of various sizes covered with a continuous film of water, and the properties which in theory it should possess under such a hypothesis were found not to accord too well with the results of experiment. But when the existence of soil colloids was understood, the differences between theory and experiment tended to disappear one by one, as shown by the work of Bouyoncos in America in 1915 and of Keen in England in 1914, 1919, and 1920.
