LOCATION BOGGY OK+TXEstablished Series
TAXONOMIC CLASS: Coarse-loamy, siliceous, active, nonacid, thermic Aeric Fluvaquents
TYPICAL PEDON: Boggy fine sandy loam, on nearly level slope, in pasture.
(Colors are for moist soil unless otherwise stated. When described, the soil was wet below 30 inches.)
A1--0 to 8 inches; very dark grayish brown (10YR 3/2) fine sandy loam; common fine faint yellowish brown and strong brown redox iron concentrations; weak fine granular structure; very friable; common fine and medium roots inside peds; medium acid; clear smooth boundary. (8 to 22 inches thick)
A2--8 to 20 inches; dark grayish brown (10YR 4/2) fine sandy loam; common fine distinct gray redox iron depletions and yellowish brown redox iron concentrations; weak fine granular structure; very friable; common fine and medium roots inside peds; medium acid; gradual smooth boundary. (0 to 18 inches thick)
C--20 to 60 inches; grayish brown (10YR 5/2) fine sandy loam; common fine and medium distinct gray (10YR 6/1) redox iron depletions and strong brown (7.5YR 5/6) redox iron concentrations; massive; very friable; common fine and medium roots inside peds in upper part and few fine roots inside peds in lower part; common thin strata of loamy fine sand and loam; strongly acid.
TYPE LOCATION: Pushmataha County, Oklahoma; about 200 feet west and 1,900 feet south of northeast corner of sec. 30 T. 4 S., R. 16 E.
RANGE IN CHARACTERISTICS: Texture throughout is fine sandy loam or loam. Reaction is slightly acid or medium acid to a depth of 21 inches and ranges from strongly to medium acid below 21 inches.
The A horizon has hue of 7.5YR or 10YR, value of 3 to 6, and chroma of 1 or 2, but includes chroma of 3 in pedons that have dominantly 2 chroma C horizons that occur within 20 inches of the surface. Where value and chroma are less than 3.5 in the A1 horizon, the horizon is less than 10 inches thick. Redox concentrations or depletions of iron are in shades of brown or gray. Thickness of the A horizons ranges from 12 to 32 inches.
The C horizon has hue of 7.5YR or 10YR, value of 4 to 7, and chromas of 1 or 2, but includes chroma of 3 in pedons that have A horizons that are dominantly 2 chroma and extend below a depth of 20 inches. Redox concentrations or depletions of iron are in shades of brown or gray. Reaction ranges from slightly acid to strongly acid.
COMPETING SERIES: The Kian series is the only other series in the family. Kian soils are poorer drained, have warmer mean annual temperatures and receive more than 30 inches of summer rainfall.
GEOGRAPHIC SETTING: Boggy soils are on narrow flood plains, usually less than 0.25 mile in width, of the Western Coastal Plains (MLRA 133B). These soils are formed in recent alluvial sediments that weathered from rocks of Cretaceous age. Slopes range from 0 to 1 percent. Mean annual precipitation ranges from 40 to 46 inches and is evenly distributed throughout the year. Mean annual air temperature ranges from 60 degrees to 66 degrees F. Thornthwaite annual P-E indices ranges from 64 to 76. Frost free days range from 200 to 225. Elevation ranges from 200 to 800 feet. The climate is humid.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bernow, Bosville, and Romia series. Bernow, Bosville, and Romia soils are on adjacent uplands and have argillic horizons.
DRAINAGE AND PERMEABILITY: Boggy soils are somewhat poorly drained. Runoff is slow and permeability is moderate. A water table is at a depth of 0 to 2 feet in winter and spring. They are frequently flooded for very brief periods from January through May.
USE AND VEGETATION: Used mainly for growing tame pasture or as forest. Native vegetation is southern red oak, green ash, hickory, red maple, sweetgum, and shortleaf pine.
DISTRIBUTION AND EXTENT: Southern Coastal Plains of Oklahoma and possibly Arkansas and Texas. The series is of moderate extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Temple, Texas
SERIES ESTABLISHED: Pushmataha County, Oklahoma; 1977.
REMARKS: These soils were formerly classified in the Alluvial great soil group and included in the Iuka and Bibb series.
Diagnostic horizons and features recognized in this series are: Ochric epipedon - the zone from the surface of the soil to a depth of 20 inches (A horizons); irregular decrease of organic carbon - stratification of loamy fine sand within 40 inches of the soil surface; Aquic moisture regime.
