Characteristics of Some Podzolic, Brown Forest, and Chernozem Soils of the Northern Portion of the Lake States

The morphology of the six great soil groups — Chernozem, Degraded Chernozem, Gray Wooded, Brown Forest, Brown Podzolic, and Podzol — with laboratory data is presented. The general distribution of these soils is shown on a schematic map. Of the five soil forming factors, three — climate, living matter, and parent materials — change notably from west to east. The other factors, topography, and age, are reasonably uniform in the areas selected for the modal soil profiles. Additional maps, illustrations of soil profiles, and related landscapes accompany the acticle. Tables of profile characteristics and laboratory analyses are arranged to show a summarized comparison of the various soil horizons of each soil.
