CHRYSLER SERIES
The Chrysler series consists of deep, moderately well drained, slowly permeable soils that formed in clayey fluvial or alluvial sediments. These soils are on stream terraces of the Coastal Plain. The rate at which water runs off the surface is medium to rapid. Slopes range from 0 to 5 percent.
TAXONOMIC CLASS: Fine, mixed, semiactive, thermic Aquic Paleudults
TYPICAL PEDON: Chrysler loam--on a nearly level stream terrace under mixed hardwoods and pine at an elevation of about 65 feet. (Colors are for moist soil.)
Ap--0 to 7 inches; brown (10YR 4/3) loam; moderate fine granular structure; very friable; common fine roots; strongly acid; clear smooth boundary. (3 to 7 inches thick)
Bt1--7 to 14 inches; yellowish red (5YR 5/6) silty clay; weak medium subangular blocky structure; firm; few fine roots; thin continuous clay films on faces of peds; very strongly acid; few fine flakes of mica; gradual wavy boundary.
Bt2--14 to 27 inches; mottled red (2.5YR 4/6), yellowish brown (10YR 5/6), and yellowish red (5YR 5/6) clay; moderate fine subangular blocky structure; very firm; few fine roots; thin continuous clay films on faces of peds; few fine flakes of mica; strongly acid; gradual wavy boundary.
Bt3--27 to 72 inches; mottled red (2.5YR 4/6), yellowish brown (10YR 5/6), yellowish red (5YR 5/6), and light gray (10YR 7/1) clay; moderate medium blocky structure; very firm; thin continuous clay films on faces of peds; few fine flakes of mica; very strongly acid; gradual wavy boundary. (Combined thickness of the B2t horizon is 55 to more than 72 inches.)
C--72 to 96 inches; mottled red (2.5YR 4/6), yellowish red (5YR 5/6), light gray (10YR 7/1), and yellowish brown (10YR 5/6) thinly stratified sandy loam, sandy clay loam, loam, clay loam, and clay; massive; friable to very firm; very strongly acid.
TYPE LOCATION: Monroe County, Alabama; 3 miles north of Chrysler, 800 feet south and 800 feet west of the NE corner of sec. 6, T. 4 N., R. 4 E.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 60 to more than 90 inches. Fine flakes of mica range from none to common in the B and C horizons. Reaction is strongly acid or very strongly acid throughout.
The A horizon has hue of 10YR to 7.5YR, value of 4 or 5, and chroma of 2 through 4. The E horizon, where present, is 3 to 7 inches thick and has hue of 10YR, value of 5 or 6, and chroma of 3 or 4. The A and E horizons are loam, fine sandy loam, or silt loam.
The upper part of the Bt horizon has hue of 7.5YR to 2.5YR, value of 4 through 6, and chroma of 4 through 8. Many pedons are mottled with varying shades of yellow, brown, or red. Mottles of chroma 2 or less are within 30 inches of the surface. The lower part of the Bt horizon has hue of 10YR, value of 4 through 7, and chroma of 1 through 8 or it is mottled in varying shades of yellow, brown, red, and gray. Texture of the Bt horizon is clay loam, silty clay loam, silty clay, or clay. The clay content of the upper 20 inches of the Bt horizon ranges from 35 to 60 percent and averages about 45 percent. Silt content is more than 30 percent.
The C horizon is mottled red, gray, yellow, and brown. Textures are sandy loam, sandy clay loam, clay loam, or clay and are usually stratified.
COMPETING SERIES: These are the
Ackwater,
Angie, and
Tiak series. All competing have a high shrink-swell potential and much lower site indices. In addition, Ackwater and Tiak soils have a perched water table and Angie soils have a water table at 3 to 5 feet.
GEOGRAPHIC SETTING: Chrysler soils are on nearly level to gently sloping stream terraces of the Coastal Plain. Slopes range from 0 to 5 percent. The soils formed in clayey fluvial and alluvial sediments. The climate is warm and humid. Average annual temperature is 65 degrees F. and the average annual precipitation is 59 inches near the type location.
GEOGRAPHICALLY ASSOCIATED SOILS: These are
Bethera,
Cahaba,
Congaree,
Izagora,
Lenoir, and
Urbo series. Bethera soils are on lower landscape positions and are poorly drained. Cahaba soils are on higher landscape positions and are well drained, have a thinner solum, and a fine-loamy control section. Congaree soils are on adjacent flood plains, are well drained, have a fine-loamy control section, are non-acid, and do not have an argillic horizon. Izagora soils are on similar landscape positions but have a fine-loamy control section. Lenoir soils are on slightly lower landscape positions and are somewhat poorly drained. Urbo soils are on adjacent flood plains, are somewhat poorly drained, and do not have an argillic horizon.
DRAINAGE AND PERMEABILITY: Moderately well drained; medium or rapid runoff; slow permeability.
USE AND VEGETATION: Most areas are in woodland. Forests are pine and mixed hardwoods. Some areas are being used for pasture, hay, and cultivated crops.
DISTRIBUTION AND EXTENT: Stream terraces of the Coastal Plain of Alabama. The acreage is believed to be moderately extensive.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Auburn, Alabama
SERIES ESTABLISHED: Monroe County, Alabama; 1984.
REMARKS: Chrysler series was formerly included in the inactive Flint series.
Diagnostic horizons and features recognized in this pedon are:
Argillic horizon - the zone from approximately 7 to 72 inches
(Bt1, Bt2, and Bt3 horizons)
ADDITIONAL DATA: Particle-size, chemical, and mineralogy data are available for the typical pedon S79 AL-99-18 (1-4). Alabama Highway Department test data are also available for this pedon.
