LANIER SERIES

The Lanier series consists of very deep, well drained soils formed in stratified loamy alluvium and are underlain by sandy and gravelly alluvium at a depth of 41 to 76 cm (16 to 30 inches). These soils are on flood plains. Slope ranges from 0 to 2 percent. Mean annual precipitation is about 1016 mm (40 inches), and mean annual air temperature is about 12 degrees C (54 degrees F).

TAXONOMIC CLASS: Sandy-skeletal, mixed, mesic Fluventic Hapludolls

TYPICAL PEDON: Lanier fine sandy loam, on a nearly level area in a cultivated field. Colors are for moist soil unless otherwise stated.)

Ap--0 to 20 cm (0 to 8 inches); very dark grayish brown (10YR 3/2) sandy loam, grayish brown (10YR 5/2) dry; weak fine granular structure; friable; many roots; about 5 percent gravel; slightly effervescent; slightly alkaline; clear smooth boundary.

A--20 to 41 cm (8 to 16 inches); dark brown (10YR 3/3) sandy loam, brown (10YR 5/3) dry; weak medium granular structure; friable; 5 to 10 percent gravel; strongly effervescent; moderately alkaline; clear smooth boundary. [Combined thickness of the A horizon is 25 to 61 cm (10 to 24 inches).]

2C1--41 to 51 cm (16 to 20 inches); brown (10YR 4/3) very gravelly sandy loam; massive; very friable; about 60 percent rock fragments; strongly effervescent; moderately alkaline; diffuse irregular boundary.

2C2--51 to 152 cm (20 to 60 inches); brown (10YR 5/3) very gravelly loamy sand; single grain; loose; about 60 percent rock fragments; rock fragments include gravel, channers, flagstones, and cobbles; dominantly limestone; strongly effervescent; moderately alkaline.

TYPE LOCATION: Clermont County, Ohio; 1.5 miles northeast of Mt. Carmel, in Union Township; 1,920 feet west of headquarters of Cincinnati Nature Center, 100 feet east of stream channel.

RANGE IN CHARACTERISTICS:
Thickness of the solum: 25 to 61 cm (10 to 24 inches)
Rock fragments: include gravel, cobbles, and flagstones

Ap or A horizon:
Hue: 10YR
Value: 2 or 3 (4 or 5 dry)
Chroma: 1 to 3
Texture: fine sandy loam or sandy loam, or the gravelly analogs of these textures
Rock fragment content: 2 to 25 percent
Reaction: neutral to moderately alkaline

2C horizon:
Hue: 10YR
Value: 4 or 5
Chroma: 2 or 3
Texture: sandy loam, gravelly sandy loam, or very gravelly sandy loam above a depth of 41 to 76 cm (16 to 30 inches); stratified gravelly to extremely loamy sand or sand below
Rock fragment content: 2 to 25 percent above a depth of 41 to 76 cm (16 to 30 inches); 35 to 70 percent below
Reaction: slightly alkaline or moderately alkaline

COMPETING SERIES: There are no other series in the same family. Genesee, Landes, Rodman, and Ross series are in related families. Genesee and Ross soils are fine-loamy, and in addition, Genesee soils have an ochric epipedon. Landes soils are coarse-loamy. Rodman soils are on uplands and do not flood.

GEOGRAPHIC SETTING: Lanier soils are on nearly level flood plains that are subject to flooding. Slope ranges from 0 to 2 percent. The soils formed in stratified loamy alluvium derived from areas of calcareous drift and deposited over gravel and sand and variable-sized stream cobbles and flagstones which are mostly of local limestone origin. Limestone bedrock is at depths of more than 152 cm (60 inches). Mean annual precipitation ranges from 940 to 1041 mm (37 to 41 inches). Mean annual air temperature ranges from 11 to 13 degrees C (52 to 55 degrees F).

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Genesee, Landes, and Ross soils. Genesee, Landes, and Ross soils are on landscape positions similar to Lanier soils.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained. The potential for surface runoff is negligible. Saturated hydraulic conductivity is high or very high. Permeability is rapid or very rapid. Subject to occasional or frequent flooding from stream overflow.

USE AND VEGETATION: Many areas are cultivated. Principal crops are corn, soybeans, small grain, and meadow. Some areas remain in woods or are in permanent bluegrass pasture. Native vegetation is scattered woodland intermixed with grassy areas.

DISTRIBUTION AND EXTENT: MLRAs 111A, 111D, and 114A in southwestern Ohio and MLRA 115C in north central Illinois. The type location is in MLRA 114A. The series is of small extent, with a total area of about 7,000 acres.

SOIL SURVEY REGIONAL OFFICE (SSRO) RESPONSIBLE: AMHERST, MASSACHUSETTS

SERIES ESTABLISHED: Warren County, Ohio, 1970.

REMARKS: Stratification and irregular decrease in organic matter required for Fluvaquentic Hapludolls are not readily evident in the horizons described. However, since the soils are on flood plains and are frequently or occasionally flooded, this seems to be the best placement. Laboratory data is not available for this pedon.

Diagnostic horizons and features recognized in this pedon are:
Mollic epipedon: from the surface to a depth of 41 cm (Ap, A horizons).
