MINTER SERIES
The Minter series consists of deep, poorly drained, very slowly permeable soils that formed in stream deposited sediments. They are on nearly level to depressed areas on low stream terraces that are subject to flooding. Slopes range from 0 to 2 percent.
TAXONOMIC CLASS: Fine, mixed, semiactive, thermic Typic Endoaqualfs
TYPICAL PEDON: Minter loam--pasture. (Colors are for moist soil.)
Ap--0 to 5 inches; gray (10YR 5/1) loam; common medium faint light gray (10YR 6/1) mottles; weak medium granular structure; friable; many fine roots; strongly acid; clear wavy boundary. (4 to 13 inches thick)
Btg1--5 to 14 inches; light gray (10YR 6/1) silty clay loam; many medium distinct yellowish brown (10YR 5/8) mottles; moderate fine and medium subangular blocky structure; friable; slightly sticky; slightly plastic; few fine roots; thin patchy clay films on faces of most peds; strongly acid; clear wavy boundary. (6 to 14 inches thick)
Btg2--14 to 31 inches; light gray (N 6/0) clay; many medium distinct yellowish brown (10YR 5/6) and strong brown (7.5YR 5/8) mottles; moderate fine subangular blocky structure; firm; sticky; plastic; few fine roots; thin patchy clay films on faces of most peds; strongly acid; gradual wavy boundary. (12 to 32 inches thick)
Btg3--31 to 44 inches; light gray (N 6/0) clay; many medium distinct yellowish brown (10YR 5/6) and common medium prominent red (2.5YR 4/6) mottles; moderate fine subangular blocky structure; firm; sticky; plastic; few fine roots; thin patchy clay films on faces of most peds; few fine flakes of mica; strongly acid; gradual wavy boundary. (10 to 24 inches thick)
Btg4--44 to 72 inches; light gray (N 6/0) clay loam; many coarse distinct yellowish brown (10YR 5/6) and strong brown (7.5YR 5/6) mottles; moderate fine subangular blocky structure; firm; sticky; plastic; thin patchy clay films on faces of most peds; few fine flakes of mica; strongly acid.
TYPE LOCATION: Dallas County, Alabama; 0.4 mile south of Alabama Highway 14 and 0.6 mile east of Race Street in Selma, Alabama, 1200 feet north and 500 feet east of the SW corner of the NW1/4, sec. 29, T. 17 N., R. 11 E.
RANGE IN CHARACTERISTICS: Solum thickness exceeds 60 inches. Reaction is strongly acid or very strongly acid in the upper part and ranges from strongly acid to slightly acid in the lower subsoil.
The A or Ap horizon has hue of 7.5YR, 10YR, or 2.5Y, value of 4 to 6, and chroma of 2 or less. Redox features in shades of brown or gray are in most pedons. Texture is loam, silt loam, clay loam, or silty clay loam.
Some pedons have a thin E horizon with hue of 10YR or 2.5Y, value of 5 or 6, and chroma of 1 or 2. Texture is loam, sandy loam, or fine sandy loam.
Some pedons have a thin BA horizon with hue of 7.5YR or 10YR, value of 5, and chroma of 1 or less, or value of 6 and chroma of 2 or less. Most pedons have few to common redox features in shades of yellow and brown. Pedons without higher chroma redox features have chroma of 1 or less. Texture is clay loam or silty clay loam.
The Btg horizons have hue of 10YR, 2.5Y, or 5Y, value of 4 or 5, and chroma of 1 or less, or value of 6 or 7 and chroma of 2 or less with few to many redox features in shades of yellow, red, or brown. Texture is clay loam, silty clay loam, silty clay, or clay. The control section averages from 35 to 50 percent clay and more than 30 percent silt. A few fine flakes of mica are present in the lower part of the solum.
The C horizon, where present, is stratified alluvium, variable in color and texture and often contains few to common quartz pebbles.
COMPETING SERIES: These are the
Argent and
Lightning series in the same family and the
Cherokee,
Gaylesville,
Meggett, and
Okeetee series. Argent soils have less than 30 percent silt in the control section and range from medium acid to moderately alkaline in the lower part. Cherokee and Meggett soils have abrupt texture change between the ochric epipedon and the argillic horizon. Gaylesville and Okeetee soils have a horizon in the upper Bt dominated by chromas of more than 2. Lightning soils are dry in some parts of the moisture control section for longer periods of time during the growing season.
GEOGRAPHIC SETTING: Minter soils are in old sloughs and channel meanders of low terraces. Slopes are typically less than 2 percent. They formed in loamy and clayey alluvium. Near the type location the average annual rainfall is 52.5 inches and the average annual temperature is 66.2 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing
Gaylesville soils and the
Canton Bend, Conagaree,
Leeper, McQueen,
Una, and
Wickham soils. The Canton Bend,
Congaree, McQueen, and Wickham soils are on slightly higher, more convex, positions than the Minter soils and are better drained. In addition, Congaree and Wickham soils are fine-loamy. The Leeper and Una soils are on floodplains and do not have an argillic horizon.
DRAINAGE AND PERMEABILITY: Poorly drained; negligible to very slow runoff; very slow permeability.
USE AND VEGETATION: Most areas are in forest. Some areas are used for pasture. Principal vegetation of wooded areas is bald cypress, oak, sweetgum, blackgum, water tupelo, and pine.
DISTRIBUTION AND EXTENT: Broad flood plains and terraces of Alabama, Arkansas, Mississippi, Tennessee, and North Carolina. The series is of moderate extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Auburn, Alabama
SERIES ESTABLISHED: Dallas County, Alabama; 1977.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon - the zone from the surface to a depth of about 5 inches (Ap horizon).
Argillic horizon - the zone from about 5 inches to 72 inches (Btg1, Btg2, Btg3, and Btg4 horizons).
