LOCATION FLOMATON AL+GA KY
Rev. GWH: LFR: GRB
The Flomaton series consists of very deep, excessively drained, rapidly permeable soils on uplands of the Southern Coastal Plain Major Land Resource Area (MLRA 133A). They formed in gravelly sandy marine sediments. Near the type location, the mean annual temperature is about 67 degrees F., and the mean annual precipitation is about 62 inches. Slopes range from 2 to 45 percent.
TAXONOMIC CLASS: Sandy-skeletal, siliceous, thermic Lamellic Paleudults
TYPICAL PEDON: Flomaton gravelly loamy sand, in a forested area (Colors are for moist soil).
A--0 to 3 inches; dark grayish brown (10YR 4/2) gravelly loamy sand; weak medium granular structure; very friable; about 15 percent, by volume, pebbles; strongly acid; clear wavy boundary. (0 to 5 inches thick)
E1--3 to 9 inches; light yellowish brown (10YR 6/4) gravelly loamy sand; single grain; loose; about 25 percent, by volume, pebbles; strongly acid; gradual wavy boundary.
E2--9 to 40 inches; brownish yellow (10YR 6/6) very gravelly loamy sand; single grain; loose; about 20 percent of sand grains and pebbles coated with fines of reddish yellow (7.5YR 6/6) and occur mostly in lower 10 inches; about 55 percent, by volume, pebbles; strongly acid; gradual wavy boundary. (Combined thickness of the E horizons range from 13 to 48 inches in thickness)
E&Bt--40 to 72 inches; brownish yellow (10YR 6/6) very gravelly loamy sand (E); single grain; loose; lamellae of yellowish red (5YR 5/6) gravelly sandy loam, 0.25 to 2.0 inches thick and 0.5 to 4.0 inches apart (Bt); single grain; massive; very friable; lamellae occupying about 35 percent of the horizon generally are wavy and continuous; pebbles and sand grains well coated and bridged with clay; about 60 percent, by volume, pebbles; strongly acid.
TYPE LOCATION: Escambia County, Alabama. Approximately 0.4 mile south of Peacock store at Little Rock and about 50 feet east of road in the SE1/4, SE1/4, NW1/4 Sec. 29, T. 2 N., R. 7 E.
RANGE IN CHARACTERISTICS: Solum thickness is more than 60 inches. The combined thickness of the A horizon above the zone of lamellae is 25 to 50 inches. Pebbles and cobbles range from 20 to 70 percent, by volume, in the A horizon and from 35 to 70 percent, by volume, in the E, the E&Bt and the Bt horizons. Reaction ranges from very strongly acid to moderately acid throughout except where the surface has been limed.
The A or Ap horizon has hue of 10YR, value of 3 or 4, and chroma of 2 or 3. Texture is gravelly sand, very gravelly sand, gravelly loamy sand or very gravelly loamy sand.
The E horizon has hue of 7.5YR or 10YR, value of 6 through 8, and chroma of 3 through 8. Pebbles and/or cobbles range from 20 to 70 percent, by volume. Texture is gravelly sand, very gravelly sand, gravelly loamy sand or very gravelly loamy sand.
The E portion of the E&Bt horizon has the same range of colors and texture as the E horizon. The Bt portion is composed of lamellae that have hue of 5Yr or 7.5Yr, value of 5 or 6, and chroma of 6 or 8. The lamellae are thicker in the lower part of some pedons and in places grade into a uniform Bt horizon containing no lamellae. Texture is gravelly loamy sand, gravelly sandy loam, gravelly sandy clay loam or their very gravelly counterparts.
The Bt horizon, where present, has hue of 2.5Yr to 7.5YR, value of 4 to 6, and chroma of 6 or 8. Texture is gravelly loamy sand, gravelly sandy loam, gravelly sandy clay loam or their very gravelly counterparts.
COMPETING SERIES: There are no other known series in the same family.
GEOGRAPHIC SETTING: Flomaton soils are on dissected areas of the sloping uplands. Slopes range from 2 percent on ridge tops to 45 percent on side slopes. They formed in marine or stream deposited sands and loams very high in gravel. The climate is humid subtropical. Near the type location, the mean temperature is about 67 degrees F., and the mean annual precipitation is about 62 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Wagram series. All of these soils, with the exception of Saffell, have less than 35 percent, by volume, coarse fragments and textures finer than loamy fine sand in all parts of the argillic horizon. All of these soils with the exception of Eustis, lack lamellae in the upper 40 inches of the argillic horizon. The somewhat excessively drained Eustis soils are on higher, less sloping areas. The well drained Lucy and the somewhat excessively drained Wagram soils are on less sloping, higher positions and have sandy surface and subsurface layers that are 20 to 40 inches in thickness. In additions, Wagram soils have yellower subsoils. The well drained McLaurin soils are on higher, less sloping areas and have coarse-loamy subsoils. The well drained Norfolk, Orangeburg and Ruston soils are on less sloping, higher positions and have fine-loamy control sections. In addition, Norfolk soils have yellower subsoils and Ruston soils are rhodic. The well drained Saffell soils are on similar positions and have loamy-skeletal control sections. The somewhat excessively drained Troup soils are on similar positions and have sandy surface and subsurface layers 40 to 80 inches in thickness.
DRAINAGE AND PERMEABILITY: Excessively drained; rapid permeability; medium runoff.
USE AND VEGETATION: Most areas of Flomaton soils are in forest that consists of mixed hardwoods, loblolly pine and shortleaf pine. A few cleared areas are used for row crops, special crops and pasture.
DISTRIBUTION AND EXTENT: The Southern Coastal Plain of Alabama, Arkansas, Mississippi, Tennessee, and possibly Georgia, Louisiana, North Carolina and South Carolina. Flomaton soils are of moderate known extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Auburn, Alabama.
SERIES ESTABLISHED: Escambia County, Alabama; 1969.
REMARKS: Diagnostic horizons and features recognized in this pedon:
Ochric epipedon - the zone from 0 to 40 inches (A, E1 and E2 horizons).
Presence of lamellae - the zone from 40 to 72 inches (the Bt portion of the Bt&E horizon).
Flomaton soils were formerly mapped as gravelly phases of the Guin and Alaga series.
Flomaton soils are in MLRA 133A.
ADDITIONAL DATA: There is no known soil data on the Flomaton series.
