Abstract

The extent and distribution of soils that occur in depressional areas in the Clarion-Nicollet-Webster soil association have been estimated for Iowa counties from a randomly selected sample. The sample consisted of detailed soil maps of approximately 1000 quarter-section (each about 160 acres), or about 2 percent of the total land area. The data from the soil maps of the samples were projected to give estimates of soil conditions by counties and for the area as a whole. The acreage of depressional soils is estimated to be 4.8 percent of the total soil association area with significant variation between counties. The following data are reported by counties for mineral and organic soils: (1) percentage of quarter-sections with depressional soil areas, (2) average number and acreage of depressional areas per quarter-section, and (3) size class distribution of depressional areas.
