Abstract
AbstractSoil samples were collected from two Fayette soils developed from Peorian loess, one Milaca formed from non‐calcareous glacial till of Cary substage of the Wisconsin, and one Hayden soil developed from calcareous glacial till of Mankato substage of the Wisconsin. Morphological observations placed these soils in the Gray‐Brown Podzolic group. Mechanical analysis showed these soils to be silt loams. Some accumulation of clay in the B2 horizon substantiated field observations of some podzolization having occurred.The clay material less than 0.5µ in size was separated from the A1, A2, B1, B2, and C horizons of these profiles. Total chemical analysis of the clay fraction showed little differentiation in content of inorganic constituents within and between profiles. X‐ray diffraction and differential thermal analysis of some of the clays indicated clay minerals largely of the montmorillonitic type. Relatively high total exchange capacities of the clays were indicative also of montmorillonitic types of clay minerals.
