ties of the clay fraction.. Studies dealing with the fixation and release of such nutrients as phosphorus and potassium are usually facilitated by separating the clay fraction from the soil. Chemical or mineralogical studies can be made by separating and fractionating the clay from comparatively small samples of soil (2, 6). Where larger quantities of clay are needed for more extensive studies of clay properties, the separation and fractionation process becomes more arduous (i). In an investigation designed to study the properties of clays from some Kentucky soils, it was necessary to separate comparatively large quantities of clay and make several rather fine separations within the clay fraction. This report gives the method of separation of surface soils of the Pearman and Maury series and some preliminary data on the properties of the clay fractions.
