Description

These claypan areas are more than a mere nuisance. They are harder to work than normal soils, and they are not as productive. They need to be improved. The field phases of this work were primarily deep plowing, irrigation, and addition of certain soil amendments. The laboratory phases were measurements of those characteristics which were presumed to be affected by the field practices. An Aberdeen silty clay loam (glossic Udic Natriboroll) site was leased for the 8-year experiment. The genetic claypan exists from about the 9- to 21-inch depth, but varies in thick ness and intensity of development.
Small areas of certain associated soils were found, on detailed mapping of the site. Those recognized were Exline (Leptic Natriboroll), Harmony ( Pachic Udic Natriboroll), and Tetonk a (Argiaquic Argialboroll). These areas were delineated during the original sampling operation. The site selected was in the S 1/2 of S 1/2 of NE 1/ 4 sec. 20 , Tl l 7N, R63W, in Spink County.
