Common dark-colored coats on faces of peds<br />
Some pedons have redoximorphic features of low or high chroma within a depth of 75<br />
centimeters<br />
BC horizon:<br />
Hue--10YR<br />
Value--3 to 5<br />
Chroma--3 or 4<br />
Texture--silty clay loam or silt loam<br />
Clay content--25 to 32 percent<br />
Sand content--1 to 10 percent<br />
Reaction--slightly acid to slightly alkaline<br />
Some pedons have common redoximorphic features with chroma range of 1 to 6<br />

Anthon--have a sand content of more than 35 percent within a depth of 150 centimeters<br />
Huntsville--have a clay content that averages 18 to 27 percent in the particle-size control section<br />
Ivan--have carbonates within a depth of 25 centimeters<br />
Kahola--have carbonates within a depth of 100 centimeters<br />
Kennebec--have a clay content that averages 18 to 30 percent in the particle-size control section<br />
and have a matrix chroma of 1 or 2 in the throughout the series control section<br />
Kenridge--have a matrix chroma of 2 immediately below the mollic epipedon<br />
Lindstrom--have a clay content that averages 18 to 24 percent in the particle-size control section<br />
Napier--have a clay content that averages 20 to 27 percent in the particle-size control section<br />
Rossville--are in areas with a mean annual air temperature ranges from 11 to 13 degrees C and<br />
have a clay content of 12 to 26 percent in the lower third of the series control section<br />
Sturkie--have a clay content that averages less than 30 percent in the particle-size control section<br />
Worthen--have a clay content that averages 15 to 26 percent in the particle-size control section<br />
