SADLER SERIES

The Sadler series consists of deep or very deep, moderately well drained soils with a fragipan in the subsoil. The soil formed in a mantle of loess underlain by residuum of acid sandstone, siltstone, and shale on level to rolling upland ridgetops. Slopes range from 0 to 12 percent.

TAXONOMIC CLASS: Fine-silty, mixed, semiactive, mesic Oxyaquic Fraglossudalfs

TYPICAL PEDON: Sadler silt loam cultivated field. (Colors are for moist soil.)

Ap--0 to 7 inches, brown (10YR 4/3) silt loam; weak fine granular structure; very friable; many fine roots; few fine dark brown (10YR 3/3) iron and manganese concretions; strongly acid; abrupt smooth boundary. (5 to 10 inches thick)

Bt--7 to 20 inches, yellowish brown (10YR 5/6) silt loam; weak medium subangular blocky structure; friable; many fine roots; few fine pores; common fine distinct dark yellowish brown (10YR 4/4) clay films on faces of peds; few fine dark brown (10YR 3/3) iron and manganese concretions; very strongly acid; clear smooth boundary.

(2 to 6 inches thick)

2Btx--24 to 48 inches, 40 percent yellowish brown (10YR 5/6), 30 percent dark brown (10YR 3/3), and 30 percent light brownish gray (10YR 6/2) silt loam; weak very coarse prismatic structure parting to weak medium angular blocky; very firm; few very fine roots in seams between prisms; common fine distinct gray (10YR 6/1) clay films on faces of prisms and coating secondary peds; common fine and medium distinct gray (10YR 6/1) silt coatings on prism faces and in vertical seams;; few fine black (N2.5/0) iron and manganese concretions; brittle in more than 60 percent of the mass; very strongly acid; gradual wavy boundary. (12 to 30 inches thick)

2Bt--48 to 62 inches, light olive brown (2.5Y 5/4) clay loam; moderate medium angular blocky structure; firm; common medium prominent gray (10YR 6/1) clay films on faces of peds; few fine black (N2.5/0) iron and manganese concretions; few fine prominent grayish brown (10YR 5/2) iron depletions; 2 percent channers of sandstone; very strongly acid; clear smooth boundary. (0 to 20 inches thick)

2C--62 to 76 inches, 50 percent gray (5Y 6/1) and 50 percent yellowish brown (10YR 5/8) loam; massive; firm; few fine black (N2.5/0) iron and manganese concretions; 2 percent channers of sandstone; very strongly acid. (10 to 40 inches thick)

2R--76 inches, interbedded brown sandstone and weakly cemented gray shale.

TYPE LOCATION: Grayson County, Kentucky; 1.1 miles south of Caneyville on KY Hwy 185, 1.03 miles northwest of the intersection of KY Hwy 185 and Caney Creek Road, 521 feet southwest of the intersection of CD Cook Road and KY Hwy 185 in field. USGS Quad: Caneyville, KY; latitude:(N 37 degrees, 24 minutes, 31.3 seconds); longitude:(W 86 degrees, 29 minutes, 15.2 seconds)

RANGE IN CHARACTERISTICS: Depth to sandstone, siltstone, or shale bedrock ranges from 50 to greater than 100 inches. Thickness of the loess mantle ranges from 12 to 48 inches. Depth to the fragipan ranges from 18 to 32 inches. Fragments range from 0 to 30 percent in 2Btx horizon, and from 0 to 60 percent in the 2Bt and 2C horizons. Soil reaction is strongly or very strongly acid throughout, except where limed.

The Ap horizon has hue of 10YR or 2.5Y, value of 4 or 5, and chroma of 2 to 4. Texture is silt loam.

The Bt horizon has hue of 7.5YR to 2.5Y, value of 5 or 6, and chroma of 4 to 6. Texture is silt loam or silty clay loam.

The E part of the E/B horizon has hue of 10YR or 2.5Y, value of 4 to 6, and chroma of 1 to 3. Redoximorphic features as clay depletions range from 1 to 20 mm in width and comprise 55 to 70 percent of the horizon. Texture is silt or silt loam. The B part of the E/B horizon has hue of 10YR or 2.5Y, value of 4 to 6, and chroma of 4 to 8. Texture is silt loam or silty clay loam.

The 2Btx horizon has hue of 7.5YR to 5Y, with value of 3 to 6, and chroma of 1 to 6, or is an evenly mottled pattern in these colors. Redoximorphic features range from few to many in colors of red, brown, yellow, olive, and gray. Texture is silt loam, silty clay loam, loam, or clay loam.

The 2Bt and 2C horizons have hue of 7.5YR to 5Y, value of 3 to 6, and chroma of 1 to 6, or is an evenly mottled pattern in these colors. Some pedons have redoximorphic features in shades of red, brown, yellow, olive, or gray. Texture is silt loam, silty clay loam, silty clay, clay, loam, clay loam, sandy clay loam, or fine sandy loam.

COMPETING SERIES: Sadler soils have no competing series. Soils in similar families are the Cambridge, Grenada, Lawrence, Nicholson, and Otwood series. Cambridge, Lawrence, Nicholson, and Otwood soils lack an E/B horizon immediately above the fragipan. In addition, the Cambridge soils lack an argillic horizon above the fragipan. The Lawrence soils have redoximorphic features in chroma of 2 or less within the upper 10 inches of the argillic horizon. The Grenada soils are a thermic temperature regieme and formed in loess more than 48 inches thick.

GEOGRAPHIC SETTING: Sadler soils are on level to rolling upland ridgetops. Slopes range from 0 to 12 percent. The soil formed in 12 to 48 inches of loess underlain by residuum of acid sandstone, siltstone, and shale. Near the type location the mean annual temperature is 55.6 degrees F., and the mean annual precipitation is 48.9 inches.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Johnsburg, Wellston, and Zanesville series. The Johnsburg soils have redoximorphic features in chroma of 2 or less in the upper 10 inches of the Bt horizon. Wellston soils are well drained and lack fragipans. Zanesville soils lack an E/B horizon immediately above the fragipan.

DRAINAGE AND PERMEABILITY: Moderately well drained. Negligible to medium runoff. Permeability is moderate above the fragipan and slow or very slow in the fragipan.

USE AND VEGETATION: Most areas are used for corn, small grains, soybeans, tobacco, specialized truck crops, hay, and pasture. The remainder are in forest. Native vegetation is chiefly oak, hickory, maple, gum poplar, dogwood, beech, ironwood, persimmon, and sassafras.

DISTRIBUTION AND EXTENT: The Western Coalfields part of Kentucky (MLRA 120), southern and southeastern Ohio, Missouri and possibly Arkansas. The series is of moderate extent.
