Argyle silt loam. Solum thickness ranges from 4 to 8 or more feet. Thickness depends upon the amount of truncation of the Paleosol, that is the IIB horizon, before the loess was deposited. Where sola are more than 5 feet thick, chroma is either less than 5 and hue is 7.5YR or redder or clay content decreases more than 20 percent from the maximum within depths of 60 inches.
Structure ranges from weak to moderate, fine to medium granular.
The A horizon ranges from slightly to strongly acid when not limed. The upper part of the B horizon formed in loess or other silty material. The IIB2 horizon ranges from clay loam to gravelly sandy clay loam or sandy loam. The upper 20 inches of the argillic horizon averages 27 to 35 percent clay and 15 to 35 percent fine and coarser sand. Ped faces or the matrix of some part of the IIB horizon has 5YR or redder hue.
