TYPE LOCATION: Wilcox County, Alabama; 5 miles northwest of Camden on the Lower Coastal Plain Substation. Five hundred yards east of Alabama River and 1/2 mile north of gravel road. SW1/4NW1/4 sec. 29, T. 13 N., R. 7 E.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 40 to 60 inches or more. Fine flakes of mica range from none to common in the solum and from few to many in the C horizon. Reaction ranges from very strongly acid to slightly acid in the A and E horizons and from very strongly acid to strongly acid in the B and C horizons.
The A horizon has hue of 7.5YR to 2.5Y, value of 3 to 5, and chroma of 2 to 4. It is sandy loam, fine sandy loam, loam, or silt loam.
The E horizon, where present, has hue of 10YR or 2.5Y, value of 5 or 6, and chroma of 2 to 4. It is sandy loam, fine sandy loam, loam, or silt loam.
The Bt horizon has hue of 2.5YR or 5YR, value of 4 or 5, and chroma of 6 to 8. It is silty clay loam, clay loam, silty clay or clay. Mottles are in shades of brown, yellow, and red; and, within the upper 20 inches of the Bt horizon, gray. Some pedons have an upper Bt horizon, less than 7 inches thick, with hue of 7.5YR, value of 5 or 6, and chroma of 6 or 8. Ca plus Mg content of the control section ranges from 2.5 to 4.5 meg/100 gm of soil.
The BC horizon, where present, has the same range in hue, value, and chroma as the Bt horizon; or it is mottled in varying shades of red, brown, yellow, or gray. It is sandy clay loam, loam, or clay loam.
The C horizon has hue of 2.5YR to 2.5Y, value of 5 to 8, and chroma of 1 to 8; or it is mottled with these colors. It is loamy sand, sandy loam, fine sandy loam, or sandy clay loam; or it is stratified sand to clay with a crushed clay content of 5 to 25 percent. Some pedons have a 2C horizon of loamy sand or sand below a depth of about 50 inches.
COMPETING SERIES: These are Beason, Craven, Creedmoor, Dogue, Eulonia, Helena, Lignum, Nemours, Rosenwall, Sacul, Vinita, and Wolftever series of the same family. Beason, Craven, Dogue, Helena, Lignum, and Wolftever soils have dominant colors of 7.5YR or yellower in the Bt horizons. Creedmoor soils have upper B horizons of friable loamy materials over clayey lower B horizons. Eulonia and Nemours soils have Bt horizons that are mottled gray, brown, and red or, are dominantly gray in the lower part. Sacul soils are commonly underlain by weathered shales. Rosenwall and Vinita soils have sola less than 40 inches thick over sandstone or shale.
GEOGRAPHIC SETTING: Annemaine soils are on nearly level to undulating stream and marine terraces at low elevations in the Gulf Coastal Plain. Slopes are dominantly 0 to 5 percent but range up to 8 percent. The soil formed in stratified clayey and loamy sediments. The climate is warm and humid with average annual temperature of 65 degrees F. and average annual precipitation of 53 inches near the type location.
GEOGRAPHICALLY ASSOCIATED SOILS: These are Angie, Cahaba, Canton Bend, Izagora, Lenoir, and Yonges series. Angie soils have yellowish brown Bt horizons over 60 inches in thickness. Cahaba soils are better drained and have less than 35 percent clay in the textural control section. Canton Bend soils lack chroma 2 or less mottles in the upper 24 inches of the argillic horizon and have base saturation greater than 35 percent. Izagora soils have less than 35 percent clay in the control section. Lenoir soils are somewhat poorly drained and have hue of 10YR or yellower in the Bt horizon. Yonges soils are poorly drained.
DRAINAGE AND PERMEABILITY: Moderately well drained; medium or rapid runoff; slow permeability.
USE AND VEGETATION: Largely cleared and used for the commonly produced crops and pasture. Forested areas are in mixed hardwoods and pines.
DISTRIBUTION AND EXTENT: Gulf Coastal Plain of Alabama, Georgia, and Mississippi.
MLRA OFFICE RESPONSIBLE: Auburn, Alabama
SERIES ESTABLISHED: Lowndes County, Mississippi; 1977.
REMARKS: This soil has been included with the Craven series or Craven-red subsoil-variant. This definition restricts the Annemaine series to hues of 5YR or redder and clayey Bt horizons with high Ca and Mg content in these horizons. Data for the typical pedon were obtained by the Alabama Agricultural Experiment Station - Sample - S71-A1a-66-13-(1-7*) and are available.
Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon - the zone from the surface of the soil to a depth of about 9 inches. (Ap and E horizons)
Argillic horizon - the zone from about 9 inches to 37 inches. (Bt1, Bt2 horizons)
Aquic features - have mottles that have moist color value of 4 or more and chroma of 2 or less in the upper 24 inches of the argillic horizon.
