LOUDONVILLE SERIES
The Loudonville series consists of moderately deep well drained soils formed in loamy till and underlain by sandstone or siltstone within a depth of 50 to 100 centimeters. These soils have moderately high saturated hydraulic conductivity. Slope ranges from 0 to 70 percent. Mean annual precipitation is about 940 millimeters, and mean annual air temperature is about 10.5 degrees C.
TAXONOMIC CLASS: Fine-loamy, mixed, active, mesic Ultic Hapludalfs
TYPICAL PEDON: Loudonville silt loam-on a 7 percent convex slope in a cultivated field, 20 feet from crest of slope at an elevation of 1,200 feet. (Colors are for moist soil unless otherwise stated.)
Ap -- 0 to 20 centimeters; brown (10YR 4/3) silt loam; weak fine granular structure; friable; 2 percent rock fragments; very strongly acid; abrupt smooth boundary. (6 to 10 inches thick.)
BE -- 20 to 33 centimeters; brown (7.5YR 4/4) silt loam; moderate medium subangular blocky structure; friable; 2 percent rock fragments; very strongly acid; clear smooth boundary. (0 to 20 centimeters thick.)
Bt1 -- 33 to 64 centimeters; brown (7.5YR 4/4) loam; moderate medium subangular blocky structure; friable; many faint brown (7.5YR 4/3) clay films on vertical faces of peds, and common faint on other surfaces; 5 percent rock fragments; strongly acid; gradual smooth boundary. (15 to 35 centimeters thick.)
Bt2 -- 64 to 76 centimeters; brown (7.5YR 4/4) loam; weak medium subangular blocky structure; firm; common faint brown (7.5YR 4/3) clay films on faces of peds; few black stains (iron and manganese oxides) on faces of peds; 5 percent pebbles; strongly acid; abrupt wavy boundary. (10 to 40 centimeters thick.)
2BC -- 76 to 96 centimeters; dark yellowish brown (10YR 4/4) channery loam; weak medium subangular blocky structure; friable; few faint brown (7.5YR 4/4) clay films on vertical faces of peds; 25 percent rock fragments, mostly sandstone; strongly acid; abrupt irregular boundary. (0 to 46 centimeters thick.)
2R -- 96 centimeters; olive (5Y 4/3) siltstone bedrock.
TYPE LOCATION: Columbiana County, Ohio; Middleton Township; about one mile southeast of Rogers; 50 feet south of county road junction with lane where road turns north; SW1/4 of SE1/4, sec. 8, T. 7 N., R. 1 W. East Palestine, OH topographic quadrangle; Latitude 40 degrees, 47 minutes, 8 seconds N. and Longitude 80 degrees, 36 minutes, 10 seconds W., NAD 1927.
RANGE IN CHARACTERISTICS: Solum thickness and depth to a lithic contact is 50 to 100 centimeters. The content of rock fragments (including some glacial erratics) is 0 to 5 percent in the Ap or A horizon, 2 to 25 percent in the Bt horizon, and 10 to 60 percent in 2BC and 2C horizons. The minimum depth to a horizon with more than 35 percent rock fragments, if present, is 50 centimeters.
The Ap horizon has hue of 10YR, value of 4, and chroma of 2 or 3. Uncultivated areas have an A horizon 3 to 10 centimeters thick that has value of 2 to 4, and chroma of 1 or 2. The Ap or A horizon is loam or silt loam. It is moderately acid to very strongly acid.
In most cultivated areas the E or BE horizon is mixed in the Ap, but some cultivated pedons have an E or BE horizon up to 10 centimeters thick. Undisturbed areas have an E or BE horizon 3 to 18 centimeters thick. The E or BE horizon has hue of 10YR, value of 4 to 6, and chroma of 3 or 4.
The Bt and BC horizons have hue of 10YR or 7.5YR, value of 4 or 5, and chroma of 3 to 6. Mottles are present in the lower few inches of the argillic horizon in some pedons. The Bt is loam, silt loam, clay loam, or silty clay loam; or their channery analogues. It has weak to strong medium or coarse subangular blocky structure. It is moderately acid to very strongly acid. The BC or 2BC horizon has colors similar to those of the Bt horizon. It is sandy loam, loam, loamy sand, silt loam, or silty clay loam; or their channery or very channery analogues. It is moderately acid to very strongly acid.
Some pedons have a C or 2C horizon up to 15 inches thick that has similar ranges as the BC or 2BC horizon.

Alanthus, Athol, Burkittsville, Door, Duffield, Dumfries, Ebbing, Grayford, Hayter, Lamotte, Legore, Manassas, Mechanicsburg, Middleburg, Morrison, Myersville, Panorama, Sowego, Sudley, Westmoreland, Wheeling, and Williamsburg soils do not have a lithic contact within a depth of 100 centimeters. Cateache, Kell, and Spriggs soils have a paralithic rather than lithic contact within a depth of 100 centimeters.
GEOGRAPHIC SETTING: Loudonville soils are nearly level to very steep and are formed in till which is moderately deep over sandstone or siltstone. Slope ranges from 0 to 70 percent. Loudonville soils formed in medium textured glacial till of Wisconsinan or Illinoian age although the lower part of some pedons may be derived from or influenced by the underlying rock. A thin (less than 35 centimeters) loess mantle is present in some areas. Mean annual precipitation is about 890 to 1010 millimeters, and mean annual air temperature is 10 to 12 degrees C.
GEOGRAPHICALLY ASSOCIATED SOILS:
Berks,
Dekalb,
Gilpin, and
Schaffenaker soils are in nearby areas lacking the till mantle. The competing
Mechanicsburg soils mare nearby where the depth to lithic bedrock is greater than 100 centimeters.
Canfield,
Rittman, and
Wooster soils which have fragipan horizons are adjacent where Wisconsinan till deposits are more than 100 centimeters thick.
Chagrin,
Holly,
Lobdell, and
Orrville soils are on nearby flood plains.
Chili,
Conotton, and
Wheeling soils which do not have a lithic contact are on adjacent glacial outwash and terraces.
Hanover and
Titusville soils which have fragipan horizons are adjacent where Illinoian till is more than 100 centimeters thick.
DRAINAGE AND PERMEABILITY: Well drained. The potential for surface runoff is very low to high depending on slope. Saturated hydraulic conductivity is moderately high.
USE AND VEGETATION: Most areas on slopes less than 18 percent are cleared and used for cultivated crops. Corn, small grains, and mixed hay are principal crops. Some areas are pastured. Orchards are common, especially in areas within a few miles of Lake Erie. Many areas are in nonagricultural uses. Native vegetation is hardwood forest, dominantly oak and hickory with lesser amounts of hard maple and ash.
DISTRIBUTION AND EXTENT: Central and northeastern Ohio, western Indiana, and Pennsylvania. MLRA's 111, 124, 139, and 140. The series is of large extent with more than 130,000 acres.
