A study by Hutton ( 1947, p. 426-31) of the gently sloping Prairie soils derived from Peorian, or Wisconsin, loess in southwestern Iowa showed that certain morphological, chemical, and physical properties are related to the thickness and distribution of the loess. Previous field studies had indicated that in a qualitative way, properties of the associated loess-derived Wiesenboden and Planosol soils also were related to thickness and distribution of the loess. The present study was undertaken to determine if quantitative information could be obtained on the functional relationship between certain soil properties, chiefly physical, and the loess distribution. The study consisted of collection of suitable profile samples, and the determination in the laboratory of certain properties by methods described elsewhere by Wilson et. al. (1946). Bulk samples were used for the determination of particle size distribution. Undisturbed core samples were used for measurement of permeability, volume weight, and porosity. Loess thickness borings were made manually with an extension auger as described by Hutton (1947, p. 424). Data are presented for a profile of each of the following soil series: Minden, Winterset, Haig, and Edina.
