Reaction ranges from neutral to moderately alkaline. The 2Cd horizon has hue of 10YR, value of 4 or 5, and chroma of 2 to 4. The clay content ranges from 12 to 20 percent. Sand content ranges from 30 to 50 percent. Rock fragment content, mainly glacial pebbles, ranges from 2 to 14 percent.
Reaction is slightly alkaline or moderately alkaline.
A bedrock substratum phase is recognized. Bromer, Millstadt, and Taggart soils are more than 60 inches to the base of soil development. Canal soils average more than 20 percent clay in the lower part of the control section. Coulterville soils are deeper than 40 inches to horizons with more than 15 percent fine sand and have more than 5 percent exchangeable sodium in the argillic horizon. Herbert soils do not have soil development below a depth of 40 inches.
