Recent studies on soil profiles in our laboratories have seemed somewhat inadequate, because of the need for information regarding the finer materials of the soil, especially the colloidal fraction. With the introduction of the super-centrifuge as a natural and rapid means for obtaining appreciable quantities of colloidal material an investigation of certain phases of colloidal activity as applied to soil profiles was undertaken. Results of preliminary studies of the heats of wetting, pH values and the amount of lime necessary to bring about neutralization on three typical soil profiles in Michigan are reported here.
