LOCATION BULOW FLEstablished Series
TAXONOMIC CLASS: Loamy, siliceous, semiactive, hyperthermic Arenic Hapludalfs
TYPICAL PEDON: Bulow sand--on a low sand ridge in mixed hardwoods (Colors are for moist soil).
A--0 to 5 inches; gray (10YR 6/1) rubbed, sand; single grained; loose; unrubbed mixture has a salt-and-pepper appearance; many fine roots; very strongly acid; gradual wavy boundary. (2 to 5 inches thick)
E--5 to 20 inches; very pale brown (10YR 8/2) sand; single grained; loose; common fine and medium roots; common distinct yellowish brown (10YR 5/6) stains along root channels; strongly acid; gradual wavy boundary. (9 to 30 inches thick)
Bw1--20 to 25 inches; reddish yellow (7.5YR 6/6) sand; single grained; loose; common medium roots; few distinct very pale brown (10YR 7/4) and reddish yellow (7.5YR 6/8) streaks; strongly acid; gradual wavy boundary.
Bw2--25 to 45 inches; reddish yellow (7.5YR 6/8) sand; single grained; loose; common medium and large roots; common distinct reddish yellow (7.5YR 7/6) streaks along root channels; many uncoated sand grains; neutral; gradual wavy boundary. (Combined thickness of the Bw horizons range from 15 to 50 inches)
Bt--45 to 50 inches; yellowish red (5YR 4/6) sandy clay loam; moderate medium subangular blocky structure; friable; common medium roots and worm casts; neutral; abrupt irregular boundary. (2 to 20 inches thick)
R--50+ inches; coquina rock of varying hardness that is pitted with solution holes and chambers.
TYPE LOCATION: Volusia County, Florida; approximately 2.0 miles south of the Flagler County line, about 1.9 miles west-southwest of the exchange at I-95 and old Dixie Highway, and about 0.2 mile west of Old Dixie Highway along a trail within proposed subdivision (Halifax 5-92, Real Estate Atlas of Volusia County), Sec. 37.
RANGE IN CHARACTERISTICS: Thickness of the solum and depth to coquina rock ranges from 42 to 60 inches and to more than 80 inches in the cavities of solution chambers. Depth to the upper boundary of the Bt is 40 inches or more.
Reaction ranges from very strongly acid to neutral in the A horizon and from slightly acid to neutral in the Bw and Bt horizons.
The A or AP horizon has a salt-and-pepper appearance with many clean uncoated sand grains. When rubbed, it has hue of 10YR, value of 3 to 7, and chroma of 1 or 2. Texture is sand or coarse sand.
The E horizon has hue of 10YR, value of 7 or 8, and chroma of 1 or 2. Irregular streaks in shades of red and yellow range from none to common. Texture is sand or coarse sand.
The Bw horizon has hue of 7.5YR or 10YR, value of 4 to 6, and chroma of 4 to 8. Irregular streaks in shades of red and yellow range from none to common. Texture is sand or coarse sand.
The Bt horizon has hue of 5YR, value of 4 to 6, and chroma of 4 to 8. Texture is sandy clay loam or sandy loam.
The R horizon is composed of coquina rock which is typically porous limestone. However, in places, there are beds of loose, unconsolidated coquina shells. The rock is pitted at irregular intervals with nearly vertical cylindrical solution chambers that are generally about 1.0 foot in diameter but can range up to 2.0 feet. They are filled with sandy and loamy soil material from the above horizons. The soil horizons are roughly parallel to the surface of the rock except over the cylindrical solution chambers where the horizons are broken and irregular with tonguing of soil material into the solution chambers.
COMPETING SERIES: Hague soils are the only known series in the same family. Closely related soils are the Jonesville series. Hague soils are on similar positions, have the upper boundary of the Bt horizon between 20 to 30 inches, and are very deep. Jonesville soils are superactive, are on similar positions, have the upper boundary of the Bt horizon between 20 to 30 inches, and are moderately deep to limestone bedrock.
GEOGRAPHIC SETTING: Bulow soils are on low, narrow coastal sand ridges on the low coastal plain in central Florida. Slopes range from 0 to 8 percent. They formed in sandy and loamy marine sediments underlain by differentially weathered coquina bedrock or layers of unconsolidated coquina shells. The climate is humid subtropical. The average annual precipitation ranges from 50 to 60 inches, and the average annual temperature ranges from 70 to 74 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Astatula, Cocoa, Paola, and Pomello series. All of these soils except Pomello are on similar positions. The excessively drained Astatula soils are very deep and sandy throughout. Cocoa soils are moderately deep to coquina rock. The excessively drained Paola soils are very deep and have weakly expressed spodic horizons. The somewhat poorly to moderately well drained Pomello soils are on lower positions, are very deep, and are Spodosols.
DRAINAGE AND PERMEABILITY: Well drained; rapid permeability in the A, E, and Bw horizons and moderately rapid permeability in the Bt horizon.
USE AND VEGETATION: Most areas of Bulow soils are in native vegetation of mixed hardwoods and used for wildlife habitat. Some areas are used for homes with relatively large lots. The vegetation consists of live oak, myrtle oak, magnolia, laurel oak, and in places, sand pine.
DISTRIBUTION AND EXTENT: Central Peninsular Florida. The series is of small known extent.
