LOCATION ADAMSVILLE FL
The Adamsville series consists of very deep, somewhat poorly drained, rapidly permeable soils on broad flats, low knolls, and lower side slopes. They formed in thick sandy marine or eolian sediments in central and southern Florida. Near the type location, the mean annual temperature is about 74 degrees F., and the mean annual precipitation is about 52 inches. Slopes range from 0 to 5 percent.
TAXONOMIC CLASS: Hyperthermic, uncoated Aquic Quartzipsamments
TYPICAL PEDON: Adamsville fine sand--range. (Colors are for moist soil unless otherwise stated.)
Ap--0 to 5 inches; gray (10YR 5/1) fine sand; weak fine granular structure; very friable; many fine roots; moderately acid; clear wavy boundary.
C1--5 to 9 inches; brown (10YR 5/3) fine sand; single grain; loose; common fine roots; many uncoated sand grains; few fine faint brownish yellow (10YR 6/6) masses of iron accumulation; moderately acid; gradual wavy boundary.
C2--9 to 17 inches; light yellowish brown (10YR 6/4) fine sand; single grain; loose; common fine roots; common medium white (10YR 8/1) areas of uncoated sand grains; few faint strong brown (7.5YR 5/6) masses of iron accumulation; moderately acid; gradual wavy boundary.
C3--17 to 29 inches; very pale brown (10YR 7/4) fine sand; few fine faint brownish yellow (10YR 6/6) masses of iron accumulation; single grain; loose; common fine roots; moderately acid; gradual wavy boundary.
C4--29 to 80 inches; white (10YR 8/1) fine sand; few fine faint light brownish gray (10YR 6/2) in lower part, fine sand; single grain; loose; moderately acid.
TYPE LOCATION: Sumter County, Florida; approximately 0.6 miles west of U.S. Interstate Highway 75, about 1.7 miles north on Sumter County Road 48; SE 1/4, NE 1/4, sec. 6, T. 21 S., R. 22 E.
RANGE IN CHARACTERISTICS: The depth of sand or fine sand extends to 80 inches, or more. Soil reaction ranges from very strongly acid to moderately acid in the A or Ap horizons, and very strongly acid to slightly acid in the C horizons. Silt plus clay content is less than 5 percent in the 10 to 40-inch control section.
The A or Ap horizon has hue of 10YR, value of 3 to 5, and chroma 1 or 2; or it is neutral with value of 2 to 5. Texture is fine sand or sand.
The C horizon has hue of 10YR, value of 5 to 8, and chroma of 1 to 4. Some pedons have no dominant color and are multicolored in shades of in shades of gray, yellow, and brown. Chroma of 2 or less usually dominate the lower part. Matrix colors are due to uncoated sand grains or thin coatings of organic matter.
COMPETING SERIES: These include the
Satellite series in the same family and the
Redlevel series in a closely related family. Broward soils are moderately deep and Canaveral soils have shell fragments throughout the profile. Satellite soils have less than 5 percent material that is less than 0.08 mm in diameter and have very low available water capacity. Redlevel soils are deep to limestone bedrock and are uncoated.
GEOGRAPHIC SETTING: Adamsville soils are on broad flats, low knolls, and lower slopes of the sandy uplands in lower Coastal Plains. They formed in thick beds of sandy marine sediments. Slopes range from 0 to 5 percent. The average annual soil temperature at depths of 20 inches below the surface ranges from 73 to 75 degrees F., The average annual precipitation ranges from 50 to 54 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These include
Tavares, and St. Lucie series. Basinger, Bradenton, Elred, Felda, and Ft. Drum Immokalee, Myakka, and Pompano soils are poorly drained. In addition, Basinger soils have a Bh horizon, Bradenton soils have Bt horizons, Felda soils are arenic, and Ft. Drum soils have Bk horizons, and Elred, Immokalee, and Myakka soils are Spodosols. Delray, Manatee, and Placid soils are very poorly drained. In addition, Delray soils are grossarenic, Manatee soils have Bt horizons, and Placid soils have umbric epipedons. St. Lucie soils are excessively drained. Tavares soils are moderately well drained.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained; rapid permeability.
USE AND VEGETATION: With adequate water control, many areas are used for citrus. Some areas are in improved pasture. Natural vegetation consists of pines, laurel, and water oaks with a ground cover of saw palmetto, pineland threeawn, indiangrass, bluestem grasses, and several low panicums.
DISTRIBUTION AND EXTENT: Peninsular Florida. The series is of moderate extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Auburn, Alabama.
SERIES ESTABLISHED: Hillsborough County, Florida; 1951.
REMARKS: The water table is at 18 to 42 inches for 2 to 6 months during most years. It is at 10 to 20 inches for periods of up to two weeks in some years. It is within depths of 60 inches for more than 9 months in most years.
