LOCATION PAOLA FLEstablished Series
The Paola series consists of very deep, excessively drained, very rapidly permeable soils on uplands. They formed in thick sandy marine deposits. Near the type location, the mean annual temperature is about 72 degrees F., and the mean annual precipitation is about 55 inches. Slopes range from 0 to 20 percent.
TAXONOMIC CLASS: Hyperthermic, uncoated Spodic Quartzipsamments
TYPICAL PEDON: Paola sand--forested. (Colors are for moist soil.)
A--0 to 3 inches; dark gray (10YR 4/1) crushed and rubbed sand; single grained; loose; organic matter and white (10YR 8/1) sand on the surface give the appearance of salt and pepper; many fine, medium, and coarse roots; very strongly acid; clear wavy boundary. (2 to 5 inches thick)
E--3 to 25 inches; light gray (10YR 7/1) sand with few splotches of brown (10YR 5/3) and very dark brown (10YR 2/2) stains along old root channels; single grained; loose; common fine and medium roots; very strongly acid; clear wavy boundary. (6 to 60 inches thick)
B/E--25 to 47 inches; yellowish brown (10YR 5/6) sand (Bw); single grained; loose; few tongues filled with light gray (10YR 7/1) sand from the E horizon; outer edges of the tongues are stained with grayish brown (10YR 5/2) organic material that, in places, are weakly cemented; few to common, coarse to fine soft spherical very dark grayish brown (10YR 3/2) concretions throughout; thin layers of reddish brown (5YR 4/3) weakly cemented sand occur at irregular intervals at the contact between the E horizon and the B horizon; few fine roots; very strongly acid; gradual wavy boundary. (12 to more than 50 inches thick)
C--47 to 80 inches; light yellowish brown (10YR 6/4) sand; single grained; loose; very strongly acid.
TYPE LOCATION: Seminole County, Florida. Approximately 1.25 miles northwest of the intersection of State Road 426 and 419 in Oviedo, Florida. SE 1/4, SW 1/4, Sec. 4, T. 21 S., R. 31 E.
RANGE IN CHARACTERISTICS: Depth of the profile exceeds 80 inches. Soil reaction ranges from very extremely acid to neutral throughout, except where limed. Content of silt plus clay in the 10- to 40-inch control section is less than 5 percent.
The A horizon has hue of 10YR, value of 4 to 6, and chroma of 1 or 2; or it is neutral with value of 4 to 6. Texture is fine sand or sand.
The E horizon has hue of 10YR or 2.5Y, value of 5 to 8, and chroma of 1 to 3. Texture is fine sand or sand.
The Bw part of the B/E horizon has hue of 7.5YR or 10YR, value of 5 to 7, and chroma of 4 to 8. Tongues filled with E material are present in some pedons. Weakly cemented Bh fragments 1.5 to 2.0 inches in thickness are throughout the B/E horizon in most pedons. A thin discontinuous (2 to 5 inches thick) layer with hue 5YR to 10YR, value of 3 or 4, and chroma of 3 or 4 is beneath the E horizon in some pedons. A 4 to 6 inch EB horizon occurs between the E and B/E horizon in areas without the thin, discontinuous stained layer. Many pedons have sand strippings in shades of white (10YR 8/1), gray (10YR 6/1), or very pale brown (10YR 6/2) in the lower parts of the Bw horizon. Texture is fine sand or sand.
The C horizon has hue of 10YR, value of 5 to 8, and chroma of 1 to 8. Texture is fine sand or sand.
COMPETING SERIES: These include the Dade, Orsino, and Welaka series in the same family. Dade soils are moderately deep to limestone. The moderately well drained Orsino soils have a water table at depths of 48 to 60 inches. Welaka soils have common to many shell fragments in the substratum.
GEOGRAPHIC SETTING: These soils are on uplands of the Coastal Plain. They formed sandy marine deposits more than 7 feet thick. The climate is humid subtropical. Slopes range from 0 to 20 percent. The average annual temperature is about 70 to 74 degrees F., and the average annual rainfall ranges from 50 to 60 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: In addition to the competing Orsino series, these include the Astatula, Candler, Immokalee, Myakka, Pomello, and St. Lucie series. Astatula, Candler, and St. Lucie soils lack spodic properties. Immokalee, Myakka, and Pomello soils are on lower positions and are Spodosols.
DRAINAGE AND PERMEABILITY: Excessively drained; very rapid permeability.
USE AND VEGETATION: Primarily in forest. Native vegetation consists of sand pine, slash pine, longleaf pine, scrub live oak, scattered turkey oak, and bluejack oak. The undergrowth consists of cacti, mosses, lichens, creeping dodder, rosemary, and scattered sawpalmetto.
DISTRIBUTION AND EXTENT: Peninsular Florida. The series is of large extent.
MLRA OFFICE RESPONSIBLE: Auburn, Alabama.
SERIES ESTABLISHED: Lake County, Florida; 1970.
