TAXONOMIC CLASS: Loamy, mixed, superactive, thermic Aquic Arenic Haplustalfs
TYPICAL PEDON: Meno loamy fine sand - cultivated.
(Colors are for dry soil unless otherwise stated.)
Ap--0 to 9 inches; brown (10YR 5/3) loamy fine sand, dark brown (10YR 3/3) moist; weak medium granular structure; soft, very friable; many fine and medium roots; moderately acid; gradual smooth boundary. (6 to 14 inches thick)
A--9 to 24 inches; brown (7.5YR 5/4) loamy fine sand, dark brown (7.5YR 4/4) moist; weak medium granular structure; soft, very friable; many fine roots; slightly acid; gradual smooth boundary. (10 to 26 inches thick)
Bt1--24 to 34 inches; brown (7.5YR 5/4) sandy clay loam, dark brown (7.5YR 4/4) moist; few fine faint grayish brown and strong brown redoxomorphic accumulations; weak medium subangular blocky structure; hard, friable; common fine roots; discontinous clay films on faces of peds and bridging sand grains; slightly acid; gradual smooth boundary. (7 to 14 inches thick)
Bt2--34 to 44 inches; mixed matrix of brown (7.5YR 5/4) strong brown (7.5YR 5/6) redoximorphic accumulations and gray (10YR 6/1) redoxomorphic depletions, sandy clay loam; weak medium subangular blocky structure; hard, friable; few fine roots; nearly continuous clay films on faces of peds; slightly acid; diffuse smooth boundary. (6 to 18 inches thick)
C--44 to 60 inches; mixed matrix of strong brown (7.5YR 5/6) redoximorphic accumulations and grayish brown (10YR 5/2) redoximorphic depletions, fine sandy loam; massive; slightly hard, very friable; slightly acid.
TYPE LOCATION: Major County, Oklahoma; about 4 miles south and 4 miles east of Ames; 670 feet north and 350 feet east of the southwest corner of the southeast quarter of sec. 24, T. 20 N., R. 9 W.
RANGE IN CHARACTERISTICS: Thickness of solum ranges from 34 to more than 60 inches. Thickness of A horizon ranges from 20 to 40 inches. Reaction of pedon ranges from medium acid to neutral. Depth to subhorizons having mixed matrix color or with chroma of 2 or less ranges from 20 to 30 inches.
The A horizon has hue of 7.5YR or 10YR, value of 4 to 6, and chroma of 2 to 4. The A horizon is less than 10 inches thick where the moist values and chromas are less than 3.5.
The Bt horizon has hue of 7.5YR or 10YR, value of 4 to 6, and chroma of 3 to 6 or has redoximorphic features in shades of yellow, brown, red, or gray. Texture is fine sandy loam, sandy loam, or sandy clay loam. The clay content ranges from 18 to 30 percent.
The C horizon has color and texture like the Bt horizon. In some pedons, the C horizon is stratified with thin beds of material ranging from loamy fine sand to clay loam.
COMPETING SERIES: There are no series in the same family. Soils in similar families include the Dougherty, Heatly, Nimrod, Nobscot, Stidham, and Vashti series. Dougherty, Heatly, Nobscot, and Stidham soils lack redoximorphic features within 30 inches of the surface. Nimrod soils do not decrease in clay content within 60 inches and have siliceous mineralogy. Vashti soils have a loamy fine sand A horizon less than 20 inches thick and has siliceous mineralogy.
GEOGRAPHIC SETTING: Meno soils are nearly level to very gently sloping soils on broad, slightly undulating, high stream terraces of uplands in the Central Rolling Red Prairies. Slopes range from 0 to 3 percent. These soils formed in sandy wind-blown and loamy alluvial sediments of Quaternary age. The climate is dry subhumid. Mean annual precipitation ranges from 26 to 32 inches. Mean annual air temperature ranges from 57 to 64 degrees F. Thornthwaite annual P-E index ranges from 44 to 64. Frost free days range from 190 to 230.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Carwile, Devol, Eda, and Lovedale soils. All of these soils have an A horizon less than 20 inches thick, and except for Devol and Eda soils, they have a mollic epipedon. Also, the Carwile soils have a fine control section. Eda soils have a loamy fine sand argillic horizon.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained; very low runoff; moderate permeability. These soils have endosaturation with a seasonal perched water table between depths of 24 and 36 inches from February through June.
USE AND VEGETATION: Used mainly for cultivated crops such as small grains and grain sorghums. The main native grasses are sand bluestem, little bluestem, switchgrass, and indiangrass.
DISTRIBUTION AND EXTENT: Central Rolling Red Prairies (MLRA-80A) of Oklahoma and Kansas. The series is moderately extensive.

REMARKS:
Soil Interpretation Record: Series OK0086.
Diagnostic horizons and features in this pedon are:
Ochric epipedon - zone from the surface to about 24 inches. (Ap, A horizons)
Argillic horizon - zone from 24 to 44 inches. (Bt1, Bt2 horizons)
Aquic Arenic Haplustalfs features - soils that have an ustic moisture regime; have a Ochric epipedon of loamy fine sand from 20 to 40 inches thick; have an argillic horizon with base saturation of 35 percent or more at 50 inches below the top of the argillic horizon; and are saturated with water at some period during the year and have redoximorphic features within 30 inches of the soil surface.
Moisture Regime: Udic-Ustic
