LOCATION ARREDONDO FL
The Arredondo series consists of well drained soils that are rapidly permeable in the thick sandy surface and subsurface layers and moderate to very slow in the subsoil. They formed from sandy and loamy marine sediments in central Florida on slopes ranging from 0 to 12 percent.
TAXONOMIC CLASS: Loamy, siliceous, semiactive, hyperthermic Grossarenic Paleudults
TYPICAL PEDON: Arredondo sand in improved pasture. (Colors are for moist soil.)
Ap--0 to 7 inches; dark grayish brown (10YR 4/2) sand, weak fine granular structure; very friable; many fine and medium roots; strongly acid; abrupt smooth boundary. (3 to 10 inches thick)
E1--7 to 18 inches; mixed yellowish brown (10YR 5/4) and dark yellowish brown (10YR 4/4) sand; weak fine granular structure; very friable; common fine and medium roots; sand grains are coated; few fine carbon and rounded black particles; medium acid; clear wavy boundary.
E2--18 to 46 inches; yellowish brown (10YR 5/6) sand with few medium strong brown (7.5YR 5/6) mottles; and few fine white mottles and streaks of uncoated sand grains; weak fine granular structure; very friable; few fine and medium roots; sand grains are coated; few fine carbon and black rounded particles; strongly acid; gradual wavy boundary. (Combined thickness of the E horizon is 36 to 72 inches.)
EB--46 to 65 inches; strong brown (7.5YR 5/6) sand with few fine white mottles and streaks of uncoated sand grains, streaks 1/4 inch to 3 inches long; weak medium granular structure; friable; few fine and medium roots; sand grains are well coated; few fine carbon and rounded black particles; strongly acid; gradual wavy boundary. (0 to 20 inches thick)
Bt1--65 to 70 inches; strong brown (7.5YR 5/8) loamy sand with few fine white mottles and streaks of uncoated sand grains; moderate medium granular structure; friable; few fine and medium roots; sand grains are coated and bridged with clay; few fine rounded black particles; medium acid; gradual wavy boundary. (3 to 10 inches thick)
Bt2--70 to 90 inches; strong brown (7.5YR 5/6) fine sandy loam; moderate medium granular structure and weak medium subangular blocky structure; friable; few fine roots; sand grains are coated and bridged with clay; few fine rounded black particles; strongly acid.
TYPE LOCATION: Marion County, Florida; 1/2 mile west of junction of Interstate 75 and U. S. 27; 3/4 mile north on paved road; 1/4 mile east on graded road and 1/2 mile north in a pasture about 150 feet west Interstate 75. NE1/4SE1/4, sec. 34, T. 14 S., R. 21 E.
RANGE IN CHARACTERISTICS: Solum thickness exceeds 80 inches. Soil reaction is very strongly acid to medium acid throughout. Few small weathered nodules and fragments of limestone 2 to 20 mm in size and less than 5 percent of volume are in many pedons.
The A or Ap horizon has hue of 10YR, value of 3 to 5, and chroma of 1 or 2. Texture is sand, fine sand, loamy fine sand, or loamy sand.
The E horizon has hue of 10YR, value of 4 to 7, and chroma of 3 to 8; or hue of 7.5YR, value of 5 or 6, and chroma of 8. Texture is fine sand, sand, loamy sand, and loamy fine sand. This horizon contains 5 to 15 percent silt plus clay within a depth of 10 to 40 inches below the soil surface.
The EB horizon, where present, has hue of 10YR or 7.5YR, value of 5 or 6, and chroma of 4 to 8. Texture ranges from sand to loamy fine sand. There is a texture pickup or color from the overlying horizon.
The Bt1 horizon has hue of 10YR or 7.5YR, value of 4 or 6, and chroma of 4 to 8. Texture is loamy sand, loamy fine sand, fine sandy loam, or sandy loam. The Bt2 horizon has the same matrix colors as the Bt1 horizon. Texture ranges from sandy loam to sandy clay.
COMPETING SERIES: These are the
Sparr series in the same family. Apopka soils have less than 5 percent silt plus clay between depths of 10 to 40 inches below the soil surface. Millhopper soils are moderately well drained, and Sparr soils are somewhat poorly drained.
GEOGRAPHIC SETTING: Arredondo soils are on nearly level to strongly sloping uplands in the Lower Coastal Plain. They formed in sandy and loamy marine deposits on the Ocala uplift. Near the type location, precipitation averages about 59 inches annually and mean annual temperature is about 72 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing
Sparr series and
Micanopy series. Blichton and Kanapaha soils are poorly drained. Candler, Fort Meade, Gainesville, and Lake soils lack Bt horizons. Kendrick soils have Bt horizons above a depth of 40 inches. Micanopy soils are finer textured and somewhat poorly drained.
DRAINAGE AND PERMEABILITY: Well drained, slow runoff. Permeability is rapid in the sandy layer and moderate to very slow in the subsoil.
USE AND VEGETATION: Large areas are cleared. Citrus, peanuts, watermelons, corn, and improved pasture are the principal crops. Natural vegetation consists of slash, longleaf, and loblolly pines, magnolia; red, live, laurel and water oaks; hickory, sweetgum and dogwood.
DISTRIBUTION AND EXTENT: Along the Central Florida Ridge from Pasco County through Alachua County. The series is of moderate extent.
