BAYVI SERIES

The Bayvi series consists of very deep, very poorly drained, rapidly permeable soils in tidal marshes along the Gulf coast and bays in northwest Florida. They formed in sandy marine sediments. Near the type location, the mean annual temperature is about 69 degrees F., and the mean annual precipitation is about 60 inches. Slopes range from 0 to 1 percent.

TAXONOMIC CLASS: Sandy, siliceous, thermic Cumulic Endoaquolls

TYPICAL PEDON: Bayvi loamy sand - in a tidal marsh flat. (Colors are for moist soil.)

A1--0 to 8 inches; very dark gray (10YR 3/1) loamy sand with splotches or streaks of dark gray (10YR 4/1); massive; friable; slightly sticky; common fine and few medium roots; mild sulfur odor; neutral when wet, and very strongly acid when dry; gradual smooth boundary.

A2--8 to 28 inches; very dark gray (10YR 3/1) sand with splotches or streaks of gray (10YR 5/1); massive; friable, slightly sticky, few fine and medium roots; slight sulfur odor; neutral when wet, and very strongly acid when dry; gradual smooth boundary. (Combined thickness of the A horizon is 24 to 54 inches.)

Cg1--28 to 48 inches; dark gray (10YR 4/1) loamy sand with splotches or streaks of gray (10YR 5/1); massive; loose, slightly sticky; very slight sulfur odor; slightly acid when wet, and extremely acid when dry; gradual wavy boundary. (10 to 24 inches thick)

Cg2--48 to 65 inches; gray (10YR 6/1) loamy sand with splotches or streaks of gray (10YR 5/1); weak medium granular structure; slightly sticky; slightly acid when wet, and extremely acid when dry; gradual wavy boundary. (8 to 24 inches thick)

Cg3--65 to 80 inches; gray (10YR 6/1) sand; single grained; loose; slightly acid when wet, and extremely acid when dry.

TYPE LOCATION: Bay County, Florida. North side of East Bay, south of Calloway Florida on south end of Kimbrel Ave.; SW1/4 SE1/4; sec. 19, T. 4 S., R. 13 W.; lat. 30 degrees 7 minutes 1.72 seconds N. and long. 85 degrees 34 minutes 58.62 degrees W., NAD83.

RANGE IN CHARACTERISTICS: Soil reaction ranges from slightly acid to moderately alkaline in the natural wet state, and from very strongly acid to extremely acid when dry. Some pedons have limestone bedrock below a depth of 60 inches. Sulfur content is low within depths of 28 inches. Conductivity of the saturation extract ranges from 3 to 18 mmho/cm.

The Oa horizon, where present, has hue of 7.5YR to 2.5Y, value of 2 to 4, and chroma of 1 or 2; or it is neutral with value of 2 to 4. This layer is less than 8 inches in thickness. Texture is muck.

The A horizon has hue of 10YR or 2.5Y, value of 2 to 4, and chroma of 1 or 2; or it is neutral with value of 2 to 4. Texture is sand, loamy sand, mucky loamy sand, or mucky sand.

The C horizon has hue of 10YR to 5Y, value of 4 to 7, chroma 1 or 2. Texture is sand, fine sand, or loamy sand.

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

GEOGRAPHIC SETTING: Bayvi soils are in broad, flat tidal marshes adjacent to the coastal bays. They formed in sandy marine deposits with some hydrophytic plant remains. Slopes range from 0 to 1 percent. The average annual precipitation ranges from 55 to 65 inches and the average annual temperature ranges from 67 to 71 degrees F.

GEOGRAPHICALLY ASSOCIATED SOILS: These include Chipley, Leon, Osier, and Rutlege soils. All of these soils are on slightly higher elevations not subject to flooding by tides and have base saturation less than 35 percent. In addition, the moderately well drained Chipley soils have yellow substratums, the poorly drained Leon soils have spodic horizons, and the poorly drained Osier and Rutlege soils do not have Mollic epipedons.

DRAINAGE AND PERMEABILITY: Very poorly drained; rapid permeability that is impeded by a high water table.

USE AND VEGETATION: Bayvi soils are used mainly for wildlife habitat. Native vegetation includes saltgrass, needlegrass rushes, smooth and marshhay cordgrass.

DISTRIBUTION AND EXTENT: Coastal tidal areas of northwest Florida. This series is of small known extent.

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

SERIES ESTABLISHED: Bay County, Florida; 1982.

REMARKS: Diagnostic horizons and features recognized in this pedon:

Mollic epipedon - 0 to 28 inches (A1 and A2 horizons).

These soils are flooded daily by normal high tides.

This series was formerly mapped as Tidal Marsh.
