Abstract

The presence of light colored, granular material on structural units in the lower B horizon is considered to be an atypical morphological feature in the Brunizem soils of Iowa. This study indicates that there are appreciable areas of Brunizem soils, derived from Wisconsin loess and Iowan till, in eastern Iowa with such coatings in the lower B horizon. Because the grainy gray ped coatings cannot readily be accounted for by any soil-forming factor other than vegetation, and because they are similar to coatings in some associated Gray-Brown Podzolic soils, it is inferred that their presence is generally related to a prior influence of deciduous forest. Their proper classification needs further attention.
