TENOT SERIES

The Tenot series consists of deep, somewhat poorly drained, slowly permeable soils that formed in thick deposits of loess under grass vegetation. These soils are on nearly level to very gently sloping, broad stream divides. Slopes range from 0 to 3 percent.

TAXONOMIC CLASS: Fine-silty, mixed, active, thermic Aeric Albaqualfs

TYPICAL PEDON: Tenot silt loam--cultivated. (Colors are for moist soil unless otherwise stated.)

Ap--0 to 6 inches; grayish brown (10YR 5/2) silt loam; few fine faint gray mottles; weak fine granular structure; very friable; common fine roots; common fine wormcasts; few fine soft brown bodies; medium acid; clear smooth boundary. (4 to 8 inches thick)

A2--6 to 13 inches; light yellowish brown (10YR 6/4) silt loam; common medium faint light brownish gray (10YR 6/2) mottles; weak fine subangular blocky structure; friable; few fine roots; common fine pores lined with white silt; common medium soft brown bodies; strongly acid; abrupt smooth boundary. (6 to 14 inches thick)

B21tg--13 to 24 inches; mottled dark grayish brown (10YR 4/2) and red (2.5YR 4/6) silty clay loam; surfaces of peds are dark grayish brown (10YR 4/2); compound moderate coarse prismatic and moderate medium subangular blocky structure; firm; few fine roots along surfaces of peds; few fine pores lined with clay; thick continuous clay films on surfaces of peds; few thin pale brown (10YR 6/3) silt coats (1-4 mm thick) on some vertical surfaces of peds in upper 4 inches; common medium soft black bodies; strongly acid; gradual wavy boundary. (9 to 20 inches thick)

B22t--24 to 38 inches; mottled strong brown (7.5YR 5/6), yellowish brown (10YR 5/8), and yellowish red (5YR 5/8) silty clay loam; few fine distinct grayish brown mottles; moderate medium subangular blocky structure; firm; few fine roots; few fine pores; thin patchy clay films and black stains on surfaces of peds; thin silt coats on vertical surfaces of peds; medium acid; gradual wavy boundary. (10 to 20 inches thick)

B23t--38 to 63 inches; yellowish brown (10YR 5/8) silty clay loam; few fine distinct light brownish gray and few medium distinct olive yellow (2.5Y 6/6) mottles; moderate medium subangular blocky structure; friable; few fine pores; thin patchy clay films on surfaces of peds; few fine soft red and black bodies; slightly acid; gradual wavy boundary. (10 to 30 inches thick)

B3--63 to 78 inches; mottled pale brown (10YR 6/3) and yellowish brown (10YR 5/6) silt loam; few fine faint gray and few medium prominent red (2.5YR 4/8) mottles; weak medium subangular blocky structure; friable; few fine pores; thin patchy clay films on surfaces of peds; thin silt coats on vertical surfaces of peds; neutral.

TYPE LOCATION: Evangeline Parish, Louisiana; 2 miles north of Pine Prairie; east of farmstead in field 30 yards below and east of terrace; 5 yards north of abandoned lane; NE1/4SE1/4 sec. 12, T. 3 S., R. 1 W.

RANGE IN CHARACTERISTICS: Solum thickness ranges from 50 to 100 inches. Grayish mottles due to wetness occur throughout the solum. Sand content is typically less than 3 percent but ranges
to 10 percent.

Colors of the A1 or Ap horizon are dark gray (10YR 4/1), dark grayish brown (10YR 4/2), gray (10YR 5/1), or grayish brown (10YR 5/2). It is silt loam. The horizon ranges from very strongly acid through slightly acid.

The A2 horizon is light yellowish brown (10YR 6/4), pale brown (10YR 6/3), or very pale brown (10YR 7/3, 7/4). It is silt loam. The horizon ranges from very strongly acid through medium acid. The horizon boundary between A2 and Bt is abrupt and smooth with up to 10 percent interfingering.

The surfaces of peds in the upper Bt horizon are dark gray (10YR 4/1), dark grayish brown (10YR 4/2), gray (10YR 5/1), or grayish brown (10YR 5/2). The interiors have colors of the surfaces with 40 to 70 percent mottles of red (2.5YR 4/6, 4/8), or yellowish red (5YR 4/6, 5/6, 4/8, 5/8). It is silty clay loam ranging up to 35 percent clay. The upper Bt horizon is very strongly acid to strongly acid.

The lower Bt horizons are brown (10YR 5/3), pale brown (10YR 6/3), yellowish brown (10YR 5/4, 5/6, 5/8), or strong brown (7.5YR 5/6, 5/8) with gray and red mottles. They are silty clay loam or silt loam. These horizons range from strongly acid through neutral.

COMPETING SERIES: There are no other series in this family. Other similar series are the Crowley, Dundee, Mamou, Patoutville, Springfield, and Vidrine series. Crowley soils are grayer and
have finer textured control sections. Dundee and Patoutville soils lack an abrupt textural change between A and B horizons. Mamou soils have sola less than 50 inches thick and more than 10 percent total sand. Springfield soils have fine textured B horizons. Vidrine soils are browner and have finer textured lower B horizons.

GEOGRAPHIC SETTING: Tenot soils are on nearly level to very gently sloping broad convex stream divides. They formed in thick deposits of pre-Peorian age loess under grass vegetation. Slope gradients range from 0 to 3 percent. The climate is warm and humid. Temperature averages about 68 degrees F., and the average annual rainfall is about 58 inches. Thornthwaite P-E index is about 70.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Calhoun, Duralde, Evangeline, and Frost series. The gray Calhoun soils occur at higher elevations on nearly level topography. Evangeline soils
are yellowish red and occur at lower elevations on stronger slopes. Frost soils are gray and are in the concave drainageways downslope from the Tenot soils. Where pimple mounds are present
they are associated with the Duralde soils.

DRAINAGE AND PERMEABILITY: Somewhat poorly drained; slow and medium runoff; slow permeability. The perched water table is 1 to 2 feet below the surface, December through April.

USE AND VEGETATION: Tenot soils are cropped to cotton, soybeans, truck crops, and pasture. Native vegetation was tall prairie grasses of the bluestem variety.

DISTRIBUTION AND EXTENT: Southern Louisiana and possibly Mississippi and Texas. The series is not extensive
