YELLOWJACKET SERIES
The Yellowjacket series consists of very poorly drained, deep and very deep soils on flood plains and in depressions on the lower coastal plain of Northern Peninsular Florida. They formed in highly decomposed organic materials over sandy marine sediments. Near the type location, the mean annual air temperature is about 68 degrees F., and the mean annual rainfall is about 55 inches. Slopes are less than 1 percent.
TAXONOMIC CLASS: Sandy or sandy-skeletal, siliceous, euic, thermic Terric Haplosaprists
TYPICAL PEDON: Yellowjacket muck--on the flood plain of the Suwannee River, in a wooded area. (Colors are for wet soil.)
Oa1--0 to 20 inches; black (5YR 2/1) and dark reddish brown (5YR 3/2) muck; about 35 percent fiber, less than 5 percent rubbed; weak fine granular structure; very friable; many fine, medium and coarse roots; sodium pyrophosphate extract color is very dark grayish brown (10YR 3/2); slightly acid; gradual wavy boundary.
Oa2--20 to 29 inches; dark reddish brown (5YR 2/2) muck; about 25 percent fiber, less than 5 percent rubbed; weak fine granular structure; very friable; many fine, medium and coarse roots; sodium pyrophosphate extract color is dark brown (10YR 4/3); neutral; gradual wavy boundary. (Combined thickness of the Oa horizon is 16 to 45 inches.)
AC--29 to 32 inches; dark reddish brown (5YR 3/2) mucky sand; massive; slightly sticky; few medium and coarse roots; moderately alkaline; gradual wavy boundary. (2 to 8 inches thick)
Cg1--32 to 41 inches; grayish brown (10YR 5/2) sand; single grained; loose; few medium and coarse roots; common coarse distinct very dark gray (10YR 3/1) mottles and gray (10YR 6/1) areas of iron depletions; moderately alkaline; gradual wavy boundary.
Cg2--41 to 80 inches; gray (10YR 6/1) sand; single grained; loose; moderately alkaline.
TYPE LOCATION: Dixie County, Florida. Approximately 1,500 feet east and 900 feet south of the northwest corner of Sec. 29, T. 12 S., R. 13 E.
RANGE IN CHARACTERISTICS: Fiber content of the organic material ranges from 20 to 75 percent unrubbed and 5 to 15 percent rubbed. Some organic layers contain large fragments of wood. Sodium pyrophosphate extract color has hue of 10YR, value of 3 or 4, and chroma of 1 to 4. Some pedons are underlain by limestone bedrock at a depth of 40 to 60 inches. Reaction ranges from moderately acid to moderately alkaline in the Oa horizon and from neutral to moderately alkaline in the AC and Cg horizons.
The Oa horizon has hue of 5YR to 10YR, value of 2 or 3, and chroma of 3 or less; or it is neutral with value of 2 or 3.
The AC horizon has hue of 5YR to 10YR, value of 2 or 3, and chroma of 3 or less; or it is neutral with value of 2 or 3. Texture is sand, fine sand, loamy sand, loamy fine sand, or their mucky analogs.
The Cg horizon has hue of 10YR, value of 4 to 7, and chroma of 2 or less; or it is neutral with value of 4 to 7. Texture is sand, fine sand, loamy sand, or loamy fine sand. Thin strata of sandy loam or sandy clay loam are present in some pedons.
Some pedons have an R horizon at a depth of more than 40 inches. It is hard limestone that can be chipped but not dug with a spade. Solution holes are present in some pedons. They range from 6 to 18 inches in diameter and from 18 to 45 inches in depth. They are filled with sapric material in the upper part and sand, masses on secondary calcium carbonates, or limestone fragments in the lower part. A Cr horizon may be present above the R horizon in some pedons. It is composed of soft limestone or accumulations of soft masses of calcium carbonate with hard limestone fragments.
COMPETING SERIES: There are no known series in the same family.
GEOGRAPHIC SETTING: Yellowjacket soils are in depressions and on flood plains in northwestern peninsular Florida. Slopes are less than 1 percent. The soils formed in moderately deep, well-decomposed deposits of organic remains of plants. The average annual air temperature ranges from 66 to 70 degrees F., and the average annual rainfall ranges from 50 to 60 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Chaires,
Clara,
Leon,
Maurepas,
Meadowbrook,
Pamlico,
Ridgewood,
Talquin, and
Tooles series. All of these soils except Maurepas and Pamlico are of mineral origin. Maurepas soils have more than 51 inches or more of organic material. Pamlico soils are extremely acid to strongly acid.
DRAINAGE AND PERMEABILITY: Very poorly drained; rapid permeability.
USE AND VEGETATION: Most areas of Yellowjacket soil are in natural vegetation of cypress, bay, sweetgum, redmaple, water oak, cabbage palm, greenbriar, waxmyrtle, Jamaica sawgrass, and button bush.
DISTRIBUTION AND EXTENT: Northwestern peninsular, Florida. The series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Auburn, Alabama.
SERIES ESTABLISHED: Dixie County, Florida, 1998.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Organic materials - The zone from the surface to a depth of 29 inches (Oa1 and Oa2 horizons).
These soils are frequently flooded or ponded for long periods.
