Reaction is slightly alkaline or moderately alkaline. The 3C horizon has hue of 10YR, value of 4 or 5, and chroma of 3 or 4. Texture is clay loam, silty clay loam, loam, or silt loam. Clay content is 22 to 35 percent. Rock fragment content ranges from 1 to 7 percent.
Reaction is slightly alkaline or moderately alkaline.
The calcium carbonate equivalent is 15 to 35 percent. These are the Centerburg , Cygnet , Haney , Houcktown , Jenera , Jugtown , Nicely , Reaville , Thackery , Tuscola , and Williamstown series. Centerburg soils do not have horizons in the middle part of the series control section with less than 1 percent rock fragments. Cygnet and Houcktown soils have a densic contact within 60 inches. Haney and Thackery soils have more than 7 percent rock fragments in the lower part of the series control section.
