FELICITY SERIES
The Felicity series consists of very deep, somewhat poorly drained, rapidly permeable soils. These soils formed in sandy coastal sediments on level and nearly level areas adjacent to gulf coastal beaches that are subject to flooding during storm tides. Slope ranges from 0 to 3 percent.
TAXONOMIC CLASS: Mixed, hyperthermic Aquic Udipsamments
TYPICAL PEDON: Felicity loamy fine sand--on crest of convex ridge adjacent to beach. (Colors are for moist soil.)
C1--0 to 13 inches; grayish brown (10YR 5/2) loamy fine sand; single grained; loose; about 5 percent fragments of shell; moderately alkaline; clear wavy boundary. (5 to 20 inches thick)
C2--13 to 24 inches; dark brown (10YR 4/3) and dark grayish brown (10YR 4/2) loamy fine sand; single grained; loose; about 10 percent fragments of shell; moderately alkaline; clear wavy boundary. (5 to 15 inches thick)
C3--24 to 32 inches; brown (10YR 5/3) loamy fine sand; many coarse faint dark yellowish brown (10YR 4/4) iron accumulations and few fine faint grayish brown (10YR 5/2) iron depletions; single grained; loose; moderately alkaline; clear wavy boundary. (5 to 20 inches thick)
Ab--32 to 60 inches; very dark gray (10YR 3/1) and dark gray (10YR 4/1) loamy fine sand; massive; friable; moderately alkaline.
TYPE LOCATION: Lafourche Parish, Louisiana; 10 miles south of Leeville; 0.3 mile southwest of end of LA 3090 on gulf beach. NW1/4NW1/4 sec. 25, T. 23 N., R 22 E.
RANGE IN CHARACTERISTICS: Depth to buried organic layers, or mineral horizons ranges from 40 to more than 60 inches. Sandy Ab horizons, where present, are typically at depths of 24 to 40 inches. Silt plus clay in the 10- to 40-inch control section ranges from 3 to 25 percent. Weatherable minerals in the sand and coarse silt fraction exceed 10 percent. Soil reaction ranges from neutral to moderately alkaline to a depth of 60 inches or more. Salinity ranges from moderate to high and electrical conductivity (EC) ranges from 8 to 16 mmhos/cm throughout the 10- to 40-inch control section.
The A horizon, where present, has hue of 10YR, value of 2 to 4, and chroma of 1 to 3. Texture is sand, fine sand, loamy sand, or loamy fine sand. Shell and fragments of shell range from 0 to 15 percent.
The C horizon has hue of 10YR or 5Y, value of 4 or 5, and chroma of 2 to 4. Texture is sand, fine sand, loamy sand, or loamy fine sand. Iron depletions with chroma of 2 or less are at depths of 10 to 40 inches. Shell and fragments of shell range from 0 to 15 percent.
The Ab horizon, where present, has hue of 10YR to 5Y, value of 2 to 4, and chroma of 1 to 3. Texture is sand, loamy sand, or loamy fine sand.
COMPETING SERIES: There are no other series in the same family. Similar soils are
Canaveral,
Galveston,
Mustang,
Palm Beach and
Voss series. Voss and Galveston soils have higher color values in the C horizon. Also, Voss soils have electrical conductivity (EC) less than 2 dS/m and are not inundated by salt water. Canaveral and Palm Beach soils have less than 10 percent weatherable minerals in the particle-size control section. Mustang soils have color with chroma of 1 or 2 and are Aquents.
GEOGRAPHIC SETTING: Felicity soils are on low areas adjacent to gulf coastal beaches mainly at elevations of 5 feet or less. They flood rarely to frequently by salt water during storm tides. Slope ranges from 0 to 3 percent. Near the type location the average annual rainfall is about 67 inches and the mean annual temperature is about 70 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Placedo and
Scatlake series. These soils have a clayey particle-size control section and are at lower elevations on broad level tidal marshes.
DRAINAGE AND PERMEABILITY: Felicity soils are somewhat poorly drained. Runoff is low. Permeability is very rapid. The water table is 24 to 36 inches below the soil surface and is directly related to the height of the gulf tides.
USE AND VEGETATION: Used mainly for wildlife habitat and recreation uses. This soil is either nearly void of vegetation or has a sparse stand of salt tolerant plants such as black mangrove, big leaf sumpweed, and saltwort.
DISTRIBUTION AND EXTENT: Along the Gulf Coast of Louisiana (MLRA 151). This soil is of small extent.
