VIZCAYA SERIES

The Vizcaya series consists of very shallow and shallow, very poorly drained, slowly permeable soils over limestone. They formed in loamy, marine or fresh water sediments. These soils are in broad, low freshwater marshes of the Everglades in Southern Penninsular Florida. Slopes are 0 to 2 percent.

TAXONOMIC CLASS: Clayey, mixed, superactive, isohyperthermic Lithic Endoaquolls

TYPICAL PEDON: Vizcaya mucky silt loam - in an undifferentiated group with Rock outcrop and Biscayne soils in a fresh water marsh. (Colors are for moist soil unless otherwise stated.)

A--0 to 6 inches; very dark gray (10YR 3/1) mucky silt loam; moderate medium granular structure; slightly sticky, nonplastic; 20% snail shell fragments; neutral; abrupt smooth boundary. (0 to 7 inches thick)

C--6 to 15 inches; black (10YR 2/1) clay; massive; slightly sticky; nonplastic; 10 percent snail shell fragments; neutral; abrupt irregular boundary. (6 to 20 inches thick)

2R--15 inches; hard, porous, oolitic limestone.

TYPE LOCATION: Dade County, Florida; approximately 7,700 feet west and 2,000 feet north of Chekika Park entrance road. Latitude - 25 degrees 37 minutes 19 seconds and Longitude - 80 degrees 35 minutes 56 seconds.

RANGE IN CHARACTERISTICS: Soil thickness and depth to limestone range from 4 to 20 inches. Reaction is neutral through mildly alkaline. A thin paraphyton or marl layer may occur on the surface of some pedons.

Some pedons have an Oa surface horizon less than 8 inches thick. Where present the Oa0 horizon is less than 1/2 the thickness of the soil. The Oa horizon, where present, has hue of 10YR, value of 3 or less, and chroma of 1 or 2. The fiber content is less than 33 percent unrubbed, and less than 5 percent rubbed. Sodium pyrophosphate extract has hue of 10YR value of 2 through 4, chroma 4 or less; value 5, chroma 2 through 8; value 6, chroma 3 through 8; or value 7, and chroma 4 through 8. Texture is muck.

The A horizon has hue of 10YR, value of 3 or less, and chroma of 3 or less moist; and hue of 10YR, value of 3 to 5, and chroma of 2 or 3 dry. Texture is silt loam or mucky silt loam.

The C horizon has hue of 10YR, value of 3 or less, and chroma of 3 or less; moist; and hue of 10YR, value of 3 to 5, and chroma of 2 or 3 dry. Texture is clay or sandy clay.

COMPETING SERIES: There are no other series in this taxonomic class.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Biscayne, Chekika and Dania. Biscayne soils are composed of limnic (marl) materials and are poorly drained. Chekika soils are loamy-skeletal and are somewhat poorly drained. Dania soils are composed dominantly of organic materials.

DRAINAGE AND PERMEABILITY: Very poorly and poorly drained; very slow or ponded runoff; very slow permeability. In natural areas, the water table is at or above the surface for 4 to 6 months during most years.

USE AND VEGETATION: The native vegetation on these soils consists of sawgrass, cattail and other water tolerant plants.

DISTRIBUTION AND EXTENT: Florida Everglades. The soils of this series are of small extent.

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

SERIES ESTABLISHED: Dade County, Florida; 1990. This soil was mapped as Rock land in the 1947 soil survey. This soil was unclassified.

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

Mollic epipedon - the zone from the surface or below the 0a horizon to a lithic contact (A, C horizons).
