LOCATION GOLTRY OKEstablished Series
TAXONOMIC CLASS: Mixed, thermic Psammentic Paleustalfs
TYPICAL PEDON: Goltry fine sand--rangeland. (Colors are for dry soil unless otherwise stated.)
A--0 to 12 inches; brown (10YR 5/3) fine sand, brown (10YR 4/3) moist; weak fine granular structure; soft, very friable; many fine roots; slightly acid; clear wavy boundary. (9 to 16 inches thick)
E--12 to 30 inches; light yellowish brown (10YR 6/4) fine sand, yellowish brown (10YR 5/4) moist; single grained; loose; many fine roots; slightly acid; clear wavy boundary. (8 to 36 inches thick)
E and Bt1--30 to 50 inches; very pale brown (10YR 7/3) fine sand, pale brown (10YR 6/3) moist (E), common fine faint dark grayish brown (10YR 4/2) redoximorphic depletions; single grained; loose; many uncoated sand grains; with lamellae of strong brown (7.5YR 5/6) loamy fine sand (B); the lamellae have weak subangular blocky structure; slightly hard, friable; wavy and discontinuous 1/8 inch to 3 inches thick and 1/2 inch to 5 inches apart; the lamellae have clay bridges between the sand grains; neutral; diffuse wavy boundary. (10 to 32 inches thick)
E and Bt2--50 to 80 inches; light brown (7.5YR 6/4) fine sand, brown (7.5YR 5/4) moist (E); common fine faint dark grayish brown (10YR 4/2) redoximoprhic depletions; single grained; loose; many uncoated sand grains; with lamellae of strong brown (7.5YR 5/6) fine sandy loam (B); the lamellae have weak subangular blocky structure; slightly hard, friable; wavy and discontinuous 1/8 inch to 3 inches thick and 1 inch to 5 inches apart; the lamellae have bridges between the sand grains; moderately alkaline.
TYPE LOCATION: Alfalfa County, Oklahoma; about 5 miles east and 2 miles south of Byron; 1,150 feet north and 825 feet east of the southwest corner of sec. 29, T. 28 N., R. 9 W.
RANGE IN CHARACTERISTICS: Solum thickness is more than 60 inches. Redoximorphic depletions with chromas of 1 or 2 occur at depths ranging from 30 to 60 inches. Combined thickness of the A and E horizons ranges from 20 to 50 inches.
The A or Ap horizon has hue of 7.5YR or 10YR, value of 5 to 7, and chroma of 2 to 4. It is fine sand or loamy fine sand and is single grained or has weak granular structure. Reaction ranges from slightly acid to slightly alkaline.
The E part of the E and Bt horizon has hue of 7.5YR or 10YR, value of 5 to 8, and chroma of 2 to 6. It is fine sand or loamy fine sand and reaction ranges from slightly acid to slightly alkaline.
The B part of the E and Bt horizon has hue of 5YR to 10YR, value of 5 to 7, and chroma of 3 to 8. It is fine sandy loam or loamy fine sand, but the control section averages loamy fine sand. Typically, the Bt part occurs as lamellae but in some pedons it is continuous horizontally and vertically and is loamy fine sand. The E and Bt2 horizon has the same color and texture as E and Bt1 horizon, but reaction ranges from slightly acid to moderately alkaline.
Some pedons have a C horizon of fine sand or loamy fine sand, and some pedons have lithologic discontinuities below the solum that are fine sandy loam or very fine sandy loam. The C horizon and the lithologic discontinuities range from slightly acid through moderately alkaline, and are calcareous in some pedons.
COMPETING SERIES: These are Aline series in the same family and Bienville, Dougherty, Eufaula, Likes, Meno, Nobscot, Eda, Stidham, and Tivoli series of similar families. Aline, Eda and Eufaula soils lack wetness mottles or a wet season water table within 60 inches of the surface, and are somewhat excessively drained. In addition, Eufaula soils have siliceous mineralogy. Bienville soils have siliceous mineralogy and have a udic soil moisture regime. Dougherty, Meno, and Stidham soils have a loamy control section. Likes and Tivoli soils lack an argillic horizon. Nobscot soils have a continuous vertical argillic horizon that is fine sandy loam and is 8 inches or more thick.
GEOGRAPHIC SETTING: Goltry soils are on high terraces. Slopes range from 0 to 3 percent and are undulating to slightly concave. The soils are formed in sandy eolian and alluvial sediments of Quarternary age. The average annual temperature ranges from 59 to 62 degrees F.; average annual precipitation ranges from 26 to 36 inches; and the annual Thornthwaite P-E index ranges from 44 to 58.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Aline, Eda, and Tivoli series and the Attica and Dillwyn series. All of these soils are in higher positions. Attica soils have an argillic horizon that is fine sandy loam. Dillwyn soils lack an argillic horizon.
DRAINAGE AND PERMEABILITY: Moderately well drained; negligible runoff. A water table ranges from 30 to 60 inches in wet seasons and 60 to 80 inches during dry seasons. Permeability is rapid above the water table.
USE AND VEGETATION: Largely used for grazing. The main grasses are sand bluestem, switchgrass, indiangrass, eastern gamagrass, and little bluestem. Minor acreage is cultivated with grain sorghum and small grains being the main crops.
DISTRIBUTION AND EXTENT: South-central Kansas and north-central Oklahoma. The series is inextensive.
