TAXONOMIC CLASS: Siliceous, hyperthermic Humic Psammentic Dystrudepts
TYPICAL PEDON: Orlando fine sand in forest.
(Colors are for moist soil.)
A1--0 to 8 inches; black (10YR 2/1), rubbed, fine sand; weak fine crumb structure; friable; many fine medium and coarse roots; organic matter mixed with uncoated sand grains; strongly acid; gradual wavy boundary.
A2--8 to 20 inches; very dark gray (10YR 3/1), rubbed, fine sand, weak fine crumb structure; friable; many fine and medium roots; few narrow streaks of light gray along root channels, few small pockets of light gray sand; strongly acid; gradual wavy boundary. (Combined thickness of the A horizon is 10 to 24 inches)
A/C--20 to 32 inches; dark grayish brown (10YR 4/2), rubbed, fine sand, mixed dark gray (10YR 4/1), very pale brown (10YR 7/3), and gray (10YR 6/1); single grained; loose; few fine roots; strongly acid; gradual wavy boundary. (0 to 14 inches thick)
C1--32 to 60 inches; yellowish brown (10YR 5/4), fine sand; single grained; loose; few fine roots in upper part; about 5 percent of sand grains are coated; strongly acid; gradual wavy boundary. (10 to 26 inches thick)
C2--60 to 88 inches; pale brown (10YR 6/3), fine sand, few fine faint brownish yellow and light gray mottles, few fine distinct strong brown (7.5YR 5/8) mottles; single grained; loose; common uncoated sand grains; strongly acid.
TYPE LOCATION: Hillsborough County, Florida; about 2 1/2 miles south of Lithia and about 100 feet east of the Lithia-Boyette Road; NE1/4SW1/4, sec. 34, T. 30 S., R. 21 E.
RANGE IN CHARACTERISTICS: Texture is uniform sand or fine sand to 80 inches of more deep except for a few pedons that have loamy sand or fine sandy loam lamellae below 60 inches. Silt plus clay in the 10 to 40 inch control section is less than 12 percent. Reaction ranges from moderately acid to very strongly acid throughout except where limed.
The A horizon has hue of 10YR or 2.5Y, value of 3 or less and chroma of 2 or less.
The A/C horizon, where present, is mixed color in hues 10YR or 2.5Y, value of 4 to 7, and chroma of 4 or less. Small pockets, lenses or streaks of gray to white uncoated sand grains are in this horizon.
The C horizon has hue of 5YR to 2.5Y, value of 4 to 7, and chroma of 3 to 8. In some pedons, there are few to common, fine to coarse mottles or splotches of gray to white uncoated sand but they are not indicative or wetness. A few distinct mottles in shades of brown to yellow, and lamellae are in the lower part of this horizon in some pedons.
COMPETING SERIES: These are the Ft. Meade, Florahome, and Seffner series. Florahome soils have a water table at 48 to 72 inches, and Seffner soils have a water table at 18 to 48 inches. Ft. Meade soils have uniform loamy sand or loamy fine sand texture throughout.
GEOGRAPHIC SETTING: Orlando soils are on uplands of the lower Coastal Plain in Peninsular Florida. Slopes range from 0 to 8 percent. The soils formed in thick deposits of sandy marine or fluvial sediments. The average annual precipitation is 50 to 60 inches or more, and the mean annual temperature is about 70 to 74 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Arrendondo, Astatula, Candler, Gainesville, Immokalee, Kendrick, Lake, Millhopper, and Myakka series. All of the associated soils lack an umbric epipedon. Arrendondo and Millhopper soils have argillic horizons between depths of 40 to 80 inches and Millhopper soils are not as well drained. Kendrick soils have argillic horizons between depths of 20 to 40 inches. Lake soils have 5 to 10 percent silt plus clay in the control section. Gainesville soils have 5 to 15 percent silt plus clay in the control section. Astatula and Candler soils have less than 5 percent silt plus clay in the control section. In addition, Candler soils have thin, discontinuous laminae below depths of 40 inches in the C horizon. Immokalee and Myakka soils are poorly drained and have spodic horizons.
DRAINAGE AND PERMEABILITY: Orlando soils are well drained. The water table is below depths of 72 inches. Permeability is rapid. Slow runoff.
USE AND VEGETATION: Many areas are used for growing citrus fruit, truck crops, and improved pasture. Natural vegetation is longleaf pine, laurel, live and turkey oaks, dogwood, hickory, and sweetbay, and an understory of widely spaced sawpalmetto, pineland threeawn, and paspalum.
DISTRIBUTION AND EXTENT: Mainly in Peninsular Florida. The series is of moderate extent.
