It is slightly alkaline or moderately alkaline. Accumulations of carbonate range from few to many, fine to coarse and extend into the C horizon. The C horizon has hue of 10YR or 2.5Y, value of 5 to 7 and 4 to 6 moist, and chroma of 2 to 4. It is silty clay loam, silt loam, or very fine sandy loam. It is slightly alkaline or moderately alkaline.
Mottles are in most pedons in the lower part and vary considerably in amount, size, and contrast.
Thin layers of stratified sediments are common in the lower C horizon in some pedons. 2C horizons are at depths of 40 to more than 60 inches in some pedons and consist of loam or clay loam glacial till. These are the Agar , Eakin , Fairlo , Holdrege , Monticello , Northdale , and Paka series. Agar soils formed in loess and have less sand that is coarser than very fine than the Highmore soils. Eakin soils have glacial till between depths of 20 and 40 inches.
