Clay Mineral Distribution in Five Nebraska Soils

The object of this study was to obtain information on the distribution of clay minerals in coarse clay and fine clay fractions separated from different horizons of the following soil types: Scott silt loam, Pawnee silt loam, Holdrege silt loam, Keith silt loam, and Dawes loam. These soils vary in the nature and degree of soil development. Scott and Pawnee soils are planosols developed in the chestnut soil zone of Nebraska. Holdrege and Keith are normal soils developed in the chernozem and chestnut soil zones. Advisor: H. F. Rhoades
