HOSFORD SERIES


The Hosford series consists of very deep, very poorly drained, rapidly permeable soils on lower side slopes of uplands of the Coastal Plain. They formed in sandy marine sediments that are saturated from seepage water for extended periods in most years. Slopes range from 2 to 12 percent. Near the type location, the mean annual temperature is about 69 degrees F., and the mean annual rainfall is about 55 inches.

TAXONOMIC CLASS: Sandy, siliceous, thermic Cumulic Humaquepts

TYPICAL PEDON: Hosford mucky coarse sand -- forested. (Colors are for moist soil.)

A1--0 to 4 inches; black (10YR 2/1) mucky coarse sand; weak fine granular structure; very friable; many fine and medium roots, few coarse roots; extremely acid; clear wavy boundary.

A2--4 to 66 inches; very dark grayish brown (10YR 3/2) mucky coarse sand; weak fine granular structure; very friable; common fine roots, few medium roots; faint odor of sulfur dioxide; extremely acid; clear wavy boundary. (Combined thickness of the A horizons is 24 to 70 inches.)

Cg--66 to 80 inches; dark grayish brown (10YR 4/2) sand; weak fine granular structure; very friable; few fine roots; faint odor of sulfur dioxide; extremely acid; clear wavy boundary.

TYPE LOCATION: Liberty County, Florida; approximately 1.3 miles southeast of State Road 12, adjacent to Turkey Creek; about 100 feet east and 10 feet north of the southwest corner of Sec. 23, T. 1 N., R. 7 W. Bristol topographic quadrangle; lat. 30 degree 27 minutes 37 seconds N., and long. 84 degrees 54 minutes 52 seconds W.

RANGE IN CHARACTERISTICS: Thickness of the solum is more than 60 inches. Reaction ranges from extremely acid to moderately acid throughout.

The Oa horizon, where present, does not exceed 7 inches in thickness. It has hue of 7.5 YR or 10YR, value of 2 or 3, and chroma of 1 to 2; or it is neutral and has value of 2 or 3. Texture is muck.

The A horizon has hue of 7.5YR or 10YR, value of 2 or 3, and chroma of 2 or less. Texture is fine sand, sand, coarse sand or their mucky analogs.

The Cg horizon has hue of 10YR to 5Y, value of 4 to 7, and chroma of 2 or less. Texture is fine sand, sand or coarse sand.

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

GEOGRAPHIC SETTING: Hosford soils are on toe slopes or lower side slopes of uplands in the lower Coastal Plain. They formed in sandy sediments on the toe slopes or lower part of side slopes. Slopes range from 2 to 12 percent. They remain saturated for long periods due to seepage. The average annual temperature ranges from 65 to 72 degrees F., and the average annual precipitation ranges from 50 to 60 inches.

GEOGRAPHICALLY ASSOCIATED SOILS: These include the Alpin, Blanton, Centenary, Chipley, Dorovan, Foxworth, Hurricane, Lakeland, Osier, Pamlico, and Pottsburg soils. The Alpin, Blanton, Centenary, Chipley, Foxworth, Hurricane, Lakeland, and Pottsburg soils are better drained and are on higher positions of slopes. Dorovan and Pamlico soils are organic.

DRAINAGE AND PERMEABILITY: Very poorly drained; rapid permeability.

USE AND VEGETATION: Most areas of Hosford soils are in woodland. The native vegetation consists of black titi, Atlantic white cedar, loblolly pine, bay, redbay, and scattered bald cypress.

DISTRIBUTION AND EXTENT: Coastal Plains of northern Florida. The series is of minor extent.

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

SERIES PROPOSED: Liberty County, Florida; 1991. The name is derived from a small community in Liberty County.

REMARKS: Diagnostic horizons and significant features recognized in this soil:

Aquic moisture regime

Umbric epipedon - 0 to 66 inches (A1 and A2 horizons).

The water table occurs at depths of less than 6 inches below the surface for more than 10 months during most years.

Hosford soils are in MLRA(s): 133A and 152A.
