GARCON SERIES


The Garcon series consists of very deep, somewhat poorly drained, moderately permeable soils on terraces and in the broad flats of the lower Coastal Plain. They formed in sandy and loamy marine sediments. Near the type location, the mean annual temperature is a about 67 degrees F., and the mean annual precipitation is about 55 inches. Slopes range from 0 to 5 percent.

TAXONOMIC CLASS: Loamy, siliceous, active, thermic Aquic Arenic Hapludults

TYPICAL PEDON: Garcon fine sand, occasionally flooded - wooded. (Colors are for moist soil.)

A--0 to 7 inches; very dark grayish brown (10YR 3/2) fine sand; single grained; loose; many fine roots; very strongly acid; gradual wavy boundary. (5 to 12 inches thick.)

E1--7 to 17inches; brown (10YR 5/3) fine sand; single grained; loose; many fine roots; very strongly acid; gradual wavy boundary.

E2--17 to 29 inches; pale brown (10YR 6/3) fine sand; single grained; loose; few fine roots; common medium distinct brownish yellow (10YR 6/8) masses of iron accumulation; very strongly acid; abrupt wavy boundary. (Combined thickness of the E horizon is 13 to 35 inches.)

Bt--29 to 40 inches; pale brown (10YR 6/3) fine sandy loam; weak medium subangular blocky structure; very friable; few medium roots; many coarse prominent yellowish brown (10YR 5/6) and brownish yellow (10YR 6/6) masses of iron accumulation; extremely acid; gradual wavy boundary.

Btg--40 to 58 inches; gray (10YR 6/1) sandy clay loam; moderate medium subangular blocky structure; firm; few large roots; many coarse prominent red (2.5YR 4/8) and light red (2.5YR 6/6) and common medium prominent yellowish brown (10YR 5/6) and brownish yellow (10YR 6/6) masses of iron accumulation; extremely acid; gradual wavy boundary. (Combined thickness of Bt horizon is 5 to 35 inches.)

Cg--58 to 80 inches; light gray (10YR 7/2) fine sand; weak fine granular structure; very friable; common medium prominent brownish yellow (10YR 6/6) masses of iron accumulation; extremely acid; gradual boundary.

TYPE LOCATION: Gilchrist County, Florida; approximately 0.4 mile north of graded road and 0.75 mile east of the Suwannee River; 2,170 feet north and 2,170 feet east of the southwest corner of sec. 4, T. 8 S., R. 14 E.

RANGE IN CHARACTERISTICS: Solum thickness ranges from 45 to 60 inches. Reaction ranges from extremely acid to strongly acid throughout except where the surface has been limed. The silt content is less than 20 percent.

The A or Ap horizon has hue of 10YR, value of 2 to 4, chroma of 1 or 2. Texture is loamy fine sand, loamy sand, fine sand, or sand.

The E horizon has hue of 10YR or 2.5Y, value of 5 to 7, and chroma of 3 to 6. Redoximorphic features in shades of brown, yellow, and gray range from none to common and generally increase with depth. Texture is loamy fine sand, loamy sand, fine sand, or sand.

The Bt horizon, where present, has hue of 7.5YR to 2.5Y, value of 5 to 7, and chroma of 3 to 6. Redoximorphic features in shades of gray, brown, red, or yellow range from few to common. Texture is sandy loam, fine sandy loam, or sandy clay loam.

The Btg horizon has hue of 10YR, value of 5 or 6, and chroma of 1 or 2. Masses of iron accumulation in shades of brown, yellow, or red range from few to many. Texture is sandy loam, fine sandy loam, or sandy clay loam.

The BCg horizon, where present, has the same range of colors as the Cg horizon. Texture is loamy sand, loamy fine sand, fine sandy loam, or sandy loam.

The C horizon, where present, has hue of 5YR to 10YR, value of 5 to 8, and chroma of 3 to 8; or there is no dominant color and it is variegated in shades of red, yellow, gray, and brown. Redoximorphic features in shades of red, brown, yellow, and gray range from few to many. Texture is sand or fine sand.

The Cg horizon has hue of 5YR to 10YR, value of 5 to 8, and chroma of 1 or 2. Masses of iron accumulation in shades of red, brown, and yellow range from common to many. Texture is sand or fine sand.

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

GEOGRAPHIC SETTING: Garcon soils are on broad flats and on river terraces. They formed in sandy and loamy marine sediments. Slopes range from 0 to 5 percent. The average annual air temperature ranges from about 65 to 70 degrees F., and the average annual precipitation ranges from about 50 to 60 inches.

GEOGRAPHICALLY ASSOCIATED SOILS: These include the Albany, Coosaw, Mulat, Pactolus, and Rains series. Albany soils are on similar positions but are grossarenic. Coosaw soils are on slightly higher positions and are moderately well drained. Mulat and Rains soils are poorly drained and on lower positions. In addition, Rains soils are fine-loamy.

DRAINAGE AND PERMEABILITY: Somewhat poorly drained; rapid permeability in the A and E horizons and moderate in the B and C horizons.

USE AND VEGETATION: Garcon soils are mostly for pasture and woodland. Dominant vegetation consists of slash and longleaf pine, live oak, laurel oak, water oak, sweetgum and an understory of saw palmetto, pineland threeawn (wiregrass), inkberry (gallberry), and grassleaf goldaster.

DISTRIBUTION AND EXTENT: North Florida and possibly Alabama and Georgia. The series is of moderate extent.

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

SERIES ESTABLISHED: Santa Rosa County, Florida; 1978.

REMARKS: Diagnostic horizons and features recognized in this pedon are:

Ochric epipedon--the zone from 0 to 29 inches. (A, E1, E2 horizons)

Argillic horizon--the zone from 29 to 40 inches. (Bt1, Bt2 horizons)

The seasonal high water table ranges from 18 to 36 inches below the surface for 4 to 6 months during most years. Some areas are subject to flooding.

ADDITIONAL DATA: Data from typical pedon is published in the Soil Survey of Gilchrist County, Florida, issued September 1992.
