LOCATION EBRO FLEstablished Series
TAXONOMIC CLASS: Dysic, thermic Typic Haplosaprists
TYPICAL PEDON: Ebro much on less than 1.0 percent slopes in a flood plain at an elevation of 5 feet; forested.
(Colors are for wet soil)
Oa1--0 to 6 inches; very dark grayish brown (10YR 3/2) muck; less than 5 percent fiber rubbed; massive; slightly sticky; about 30 percent mineral content; many fine, medium, and coarse roots; very strongly acid; gradual wavy boundary.
Oa2--6 to 24 inches; very dark gray (10YR 3/1) muck; less than 5 percent fiber rubbed; massive; sticky; estimated 45 percent mineral content; many fine, medium, and coarse roots; very strongly acid; gradual wavy boundary.
Oa3--24 to 74 inches; black (10YR 2/1) muck; less than 5 percent fiber rubbed; massive; sticky; many medium and coarse roots; very strongly acid.
TYPE LOCATION: Bay County Florida about 10 feet south of junction of Pine Log Creek and East River, 1/2 mile west of Oakledge Fish Camp, abount 2 1/2 miles west of Pine Log community in Bay County, about 10 miles north of Sunnyside Beach on the Gulf of Mexico, NW1/4NE/4 sec. 16, T. 1 S., R. 17 W.
RANGE IN CHARACTERISTICS: Thickness of organic materials is greater than 51 inches. Soil reaction is less than 4.5 in 0.01M calcium chloride. Logs, stumps, and fragments of wood that occupy 0 to 20 percent of the organic layers. Mineral content of the Oa horizon is variable, but there is 40 percent or more mineral matter as a weighted average between depths of 12 to 51 inches or there is a layer containing 40 to 80 percent mineral 6 inches or more thick between depths of 12 to 36 inches. There are few to common flakes on specks of mica in some pedons. The municipal fraction is 75 percent or more silt and clay.
The Oa horizon has hue of 7.5YR, 10YR, or 2.5YR, value of 2 or 3, and chroma of 1 or 2; or is neutral (N), value of 2 or 3 and chroma of 0. Fiber content is less than 10 percent unrubbed and rubbed. The organic layers are typically massive under natural wet conditions.
COMPETING SERIES: These are Dare, Dorovan, and Pungo series in the same family and the Maurepas series. Dare and Pungo soils have less than 40 percent mineral content on a weighted average in the subsurface and bottom tiers. The mineral fraction of Dorovan soils have less than 75 percent silt and clay; usually about 20 to 50 percent. Maurepas soils have a pH of 4.5 or more in the .01M calcium chloride in the control section.
GEOGRAPHIC SETTING: Ebro soils are on nearly level to level flood plains of the lower coastal plain. The soil formed under very poorly drained conditions from the remains of herbaceous and related woody hydrophytic plants. Elevation is less than 25 feet. The mean annual precipitation near the type location is about 60 inches and the mean annual temperature is about 68 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: In addition to the competing Dorovan series, these are Bibb, Chastain, Johnson, Kinston, and Maurepas series. Bibb, Chastain, Johnson, and Kinston soils are all mineral soils and are generally upstream of Ebro soils.
DRAINAGE AND PERMEABILITY: Very poorly drained; moderately slow to moderate permeability. The water table is usually near or at the soil surface. It is subject to flooding every year and lasts at least a month in most years.
USE AND VEGETATION: This soil is used mainly for production of trees. The native vegetation is dominantly bald cypress and blackgum cypress being more common in areas that pond after flood water recedes. Other hardwood trees such as red maple, sweetgum, red bay, sweetbay, and water tupelo occur along stream and river banks and occupy less than 5 to 10 percent of the flood plains. The understory consists of reeds, giant cane, and greenbriar.
DISTRIBUTION AND EXTENT: Northwest Florida and possibly Alabama, Georgia, Louisiana, Mississippi, and South Carolina. The series is of small know extent.
MLRA OFFICE RESPONSIBLE: Auburn, Alabama
SERIES ESTABLISHED: Bay County, Florida; 1982.
REMARKS: These soils were formerly mapped as a variant of the Dorovan series or possibly included with the Dorovan series. This revision transfers the type location from Walton County, Florida to Bay County, Florida. Ebro soil originally mapped in Walton County were correlated as Maurepas because data showed the soils to be euic.
