Abstract

Soil surveys in Hamilton County, Iowa, have shown a need for the revision of the Clarion and Nicollet soil series to include the fine textured variant soils found there or for the establishment of new series. The results of this study show that sufficient differences exist to warrant the establishment of new series for the fine textured variants of Clarion and Nicollet. They are higher in clay content, have lower chroma in the A horizon, have higher gravel content, have higher bulk density, are firmer in consistence, have finer and better developed structure, and mottling occurs at shallower depths, than the normal Clarion and Nicollet soils.
