Btg4--28 to 39 inches; light brownish gray (10YR 6/2) silty clay; weak medium subangular blocky structure; firm; few distinct clay films on faces of peds;common fine prominent yellowish brown (10YR 5/6) masses of iron accumulation; slightly acid; gradual smooth boundary.
Btg5--39 to 55 inches; gray (10YR 6/1) silty clay; weak fine prismatic structure; firm; few faint clay films on faces of peds; common fine prominent yellowish brown (10YR 5/6) masses of iron accumulation; neutral; clear smooth boundary. (Combined thickness of the Btg horizon is 24 to 48 inches.)
Cg--55 to 80 inches; gray (10YR 6/1) silty clay; many medium prominent yellowish brown (10YR 5/6) masses of iron accumulation; massive; firm; neutral.
TYPE LOCATION: Pettis County, Missouri; about 11 miles west of Sedalia; 75 feet north and 1,050 feet east of the southwest corner of sec. 16, T. 45 N., R. 23 W; USGS Green Ridge North quadrangle.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 40 to more than 60 inches.
The A or Ap horizon has hue of 10YR or 2.5Y, value of 4 to 6 moist and 6 or 7 dry, and chroma of 1 or 2. It is neutral to strongly acid.
The E horizon has hue of 10YR or 2.5Y and value of 5 or 6. It is slightly acid to very strongly acid. Some pedons have a BEg horizon.
The upper part of the Btg horizon has color value of 4 to 6, and chroma of 1 or 2, with distinct or prominent mottling. This horizon is silty clay loam, silty clay, or clay. It ranges from slightly acid to very strongly acid. The lower part of the Btg horizon and BCg horizon, if present is similar to the upper part of the Btg horizon in color and texture, but ranges from neutral to strongly acid.
The C horizon is silty clay loam or silty clay, value of 5 to 7, and chroma of 1 or 2. Reaction is neutral to strongly acid.
COMPETING SERIES: These are the Adeland, Library, Randolf, and Savona series. Adeland and Randolf soils have a lithic contact at 20 to 40 inches. In addition, Randold soils are active. Library soils have a lithic contact at 40 to 72 inches. Savona soils have secondary carbonates at 24 to 40 inches and have a mean annual soil temperature of less than 55 degrees F.
GEOGRAPHIC SETTING: Lamine soils are on high stream flood plains. These soils formed in alluvium. Slopes range from 0 to 2 percent. Mean annual temperature ranges from 55 to 58 degrees F., and the mean annual precipitation ranges from 36 to 42 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These include the Cotter, Dameron, Dockery, Freeburg, Moniteau, Otter, and Wiota series. Cotter and Wiota soils have mollic epipedons and are on similar positions. Dameron and Otter soils also have mollic epipedons and are on lower parts of the floodplain. Dockery soils are stratified throughout and are on lower parts of the floodplain. Freeburg and Moniteau soils are fine-silty and are on similar positions.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained. Permeability is very slow and runoff is low. The upper depth of an apparent water table is present at 1.0 to 2.5 feet during November through April. Flooding is rare or occasional for very brief or brief periods during the months of November to June.
USE AND VEGETATION: Most areas are used for row crops. Some areas are used for pasture or grass hay, and a few areas are forested. Native vegetation is bottomland hardwoods.
DISTRIBUTION AND EXTENT: The Ozark border (MLRA 116B) and Ozark Highland (MLRA 116A) areas of central Missouri. The series is of small extent.
