The published county soil surveys show that Carrington loam and silt loam soils occur extensively in the CC and CKC areas of northeast Iowa outlined in Figure 1. Most of these soil surveys were made from 1914 to 1930, and as pointed out by Simonson, Riecken and Smith ( 1952), the former Carrington series in this area is now considered to consist of several series. In the present study several morphologically different profiles formerly included with the Carrington loam and silt loam soil types were sampled and certain laboratory determinations made. The data obtained and a brief discussion of their significance are presented
