BRICKYARD SERIES

The Brickyard series consists of very deep, very poorly drained, very slowly permeable soils on forested flood plains of major rivers. They formed in silty and clayey alluvial sediments. Near the type location, the mean annual temperature is about 69 degrees F., and the mean annual precipitation is about 56 inches. Slopes range from 0 to 2 percent.

TAXONOMIC CLASS: Fine, smectitic, nonacid, thermic Typic Endoaquepts

TYPICAL PEDON: Brickyard silty clay--forested. (Colors are for moist soil)

A--0 to 4 inches; dark grayish brown (2.5Y 4/2) silty clay; moderate fine granular structure; friable; sticky, plastic; common mica flakes; common medium prominent strong brown (7.5YR 5/6) masses of iron accumulation; slightly acid; clear smooth boundary. (2 to 18 inches thick)

Bg--4 to 28 inches grayish brown (2.5Y 5/2) silty clay; weak fine subangular blocky structure; friable; sticky, plastic; common mica flakes; common medium prominent yellowish brown (10YR 5/6) masses of iron accumulation; slightly acid; clear smooth boundary. (0 to 42 inches thick)

Cg1--28 to 45 inches; grayish brown (2.5Y 5/2) silty clay loam; massive; friable; sticky, plastic; common mica flakes; neutral; gradual smooth boundary.

Cg2--45 to 80 inches; dark gray (5Y 4/1) silty clay; massive; firm; sticky, plastic; about 5 to 15 percent, by volume, partially decomposed woody and fibrous debris and few mica flakes; slightly alkaline.

TYPE LOCATION: Franklin County, Florida; approximately 20 feet west of Little Brothers Slough near its upper end on Forbes Island, about 200 feet west and about 1,800 feet north of the southeast corner of Sec. 15, T. 7 S.; R. 8 W.

RANGE IN CHARACTERISTICS: Thickness of the solum ranges from 8 to 48 inches but is typically 15 to 32 inches thick. Reaction is moderately acid to neutral in the A and Bg horizons, and moderately acid to moderately alkaline in the Cg horizon. Few to many flakes of mica range from none to common.

The A or Ap horizon has hue of 7.5YR to 2.5Y, value of 3 to 5, and chroma of 2 to 4. Redoximorphic features in shades of brown range from none to common. Texture is silt loam, loam, silty clay loam, silty clay, clay loam, clay, or their mucky analogs.

The Bg horizon, where present, has hue of 7.5YR to 2.5Y, value of 4 to 6, and chroma of 1 to 4. Where this soil has colors with chroma higher than 2, they extend to depth of less than 20 inches. Iron accumulations in shades of brown and yellow range from none to common. Texture is silty clay loam, silty clay, clay loam, or clay.

The Cg horizon has hue of 10YR to 5B, value of 3 to 7, and chroma of 0 to 2; or is neutral with value of 3 to 7. Iron accumulations in shades of brown and yellow range from none to common. Texture is silty clay loam, silty clay, clay loam, or clay. Texture is silt loam, silty clay loam, silty clay, clay loam, clay, or their mucky analogs. Below 40 inches the Cg horizon may contain organic strata. Below 60 inches it may contain strata with textures ranging from loamy sand to sandy clay.

COMPETING SERIES: There are no known series in the same family.

GEOGRAPHIC SETTING: Brickyard soils are on broad flood plains and low terraces. Slopes range from 0 to 2 percent. They formed in silty and clayey alluvial sediments. The climate is humid subtropical. The average annual precipitation ranges from 51 to 61 inches and the average annual temperature ranges from 67 to 71 degrees F.

GEOGRAPHICALLY ASSOCIATED SOILS: These are Chowan, Kenner, and Meggett series. The poorly drained Chowan soils are on similar positions but have mineral layers more than 20 inches in thickness over organic material. Kenner soils are in fresh water marshes and have organic layers throughout. The poorly drained Meggett soils are on similar to slightly higher positions and have argillic horizons.

DRAINAGE AND PERMEABILITY: Very poorly drained; very slow permeability.

USE AND VEGETATION: Most areas are in woodland but some areas have been cleared and are used for agriculture. The native vegetation consists of water tupelo, Ogeechee tupelo, cabbage palm, bald cypress, swamp tupelo, Carolina ash, sweetbay, water oak, overcup oaks, red maple, and an occasional pine.

DISTRIBUTION AND EXTENT: Apalachicola River flood plain and possibly flood plains of other southern coastal plain rivers. The series is of moderate extent.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Auburn, Alabama.

SERIES ESTABLISHED: Franklin County, Florida 1990.

REMARKS: Diagnostic horizons and features recognized in this pedon:

Ochric epipedon the zone from 0 to 4 inches (A horizon).

Fluventic properties - stratified nature of sediments and the irregular decrease in organic carbon content.

A water table is at or near the surface for about 1 to 6 months in most years and they are frequently flooded from several days up to four months in most years.
