ANNEMAINE SERIES
The Annemaine series consists of very deep, moderately well drained, slowly permeable soils on large stream and river terraces that are subject to flooding in the Southern Coastal Plain. They formed in stratified clayey and loamy fluvial sediments. Near the type location, the mean annual temperature is about 65 degrees F., and the mean annual precipitation is about 53 inches. Slopes range from 0 to 12 percent.

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. Iron accumulations in shades of brown, yellow and red range from none to common. Iron depletions in shades of gray, within the upper 20 inches of the Bt horizon, range from few to common. Texture is silty clay loam, clay loam, silty clay or clay with an average of 35 percent or more clay content in the control section.
The BC horizon, where present, has the same range in hue, value and chroma as the Bt horizon; or it is multicolored in shades of red, brown, yellow and gray. Texture 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 multicolored in shade of red, brown, yellow and gray. Texture is loamy sand, sandy loam, fine sandy loam, 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.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Auburn, Alabama.
SERIES ESTABLISHED: Lowndes County, Mississippi; 1977.
REMARKS: 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 and Bt2 horizons).
Aquic feature - Iron depletions with moist color value of 4 or more and chroma of 2 or less in the upper 24 inches of the argillic horizon. A seasonal high water table ranging from 16 to 30 inches below the surface is present in the late winter and spring of most years.
Annemaine soils were included with the Craven series or Craven-red subsoil-variant. The Annemaine series is restricted to hues of 5YR or redder and clayey Bt horizons with high Ca and Mg content in these horizons.
Annemaine soils are in MLRA 133A.
