COMPETING SERIES: These are the Madge and Ost series in the same family.
Madge soils: These soils contain less than 3 percent rounded gravel in the particle-size control section.
Ost soils: These soils contain a calcic horizon.

GEOGRAPHIC SETTING:

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Arnett, Fortyone, Madge, Quinlan, and Woodward series.
Arnett soils: These soils occur on similar positions but have an ochric epipedon.
Fortyone soils: These soils occur on lower side slopes, have an ochric epipedon, and are coarse-loamy in the particle-size control section.
Madge soils: These soils occur on lower footslopes and contain less than 3 percent rounded gravel in the particle-size control section.
Quinlan and Woodward soils: These soils occur on lower side slopes, have an ochric epipedon and a cambic horizon, and are less than 40 inches to sandstone.

DRAINAGE AND PERMEABILITY: Well drained. Permeability is moderate. Runoff is negligble on 0 to 1 percent slopes, low on 1 to 5 percent slopes, and medium on 5 to 20 percent slopes.

USE AND VEGETATION: Farry soils are used for both rangeland and cultivation. Principal crops are winter wheat and grain sorghum. Native vegetation is a mixed grass prairie.

DISTRIBUTION AND EXTENT: Western Oklahoma, southern Kansas, and possibly Texas; LRR H; Central Rolling Red Plains (MLRA-78); Moderate extent

MLRA OFFICE RESPONSIBLE: Temple, Texas

SERIES ESTABLISHED: Woods County, Oklahoma, 1995. The name comes from an old townsite.

REMARKS:
Diagnostic horizons and features recognized in this pedon are:
Particle size control section: 12 to 32 inches. (Bt and Btk horizons)

Mollic epipedon - the zone from the soil surface to a depth of approximately 12 inches (A horizon).

Argillic horizon - the zone from approximately 12 inches to 35 inches (Bt and Btk horizons).

Additional Comments: These soils were formerly included with the Shellabarger series.
