During the excavation of root systems of native and crop plants throughout the Great Plains region during the past five years (Weaver, 19I9, I920, 1922) contact has been made in more than thirty fields with the so-called hardpan. Such a layer of soil underlies much of this area of low rainfall, at depths varying from I5 inches to 3 feet. It varies from 8 inches to over i.5 feet in thickness. In connection with studies on the physical and chemical composition of the soils and their seasonal water-content under natural and cropped conditions, a more detailed study has been made of the soil in this hardened layer. The major portion of this work was done at Burlington, Colorado, a station selected as being typically representative of High Plains conditions, but analyses of hardpan from Flagler, Colorado, and Colby, Kansas, were also made.
