LYBRAND SERIES

The Lybrand series consists of very deep, well drained soils formed in silty clay loam or clay loam till of high lime content. These soils are on dissected end moraines and ground moraines. Permeability is slow. Slope ranges from 12 to 70 percent. Mean annual precipitation is about 37 inches, and mean annual temperature is about 50 degrees F.

TAXONOMIC CLASS: Fine, illitic, mesic Typic Hapludalfs

TYPICAL PEDON: Lybrand silt loam on a 16 percent slope in grass (formerly cultivated) at an elevation of 906 feet. (Colors are for moist soil unless otherwise stated.)

Ap--0 to 9 inches; dark grayish brown (10YR 4/2) silt loam, pale brown (10YR 6/3) dry; moderate medium granular structure; friable; many fine and very fine roots; 2 percent pebbles; neutral; abrupt smooth boundary. (2 to 10 inches thick)

Bt1--9 to 13 inches; yellowish brown (10YR 5/4) silty clay loam; moderate medium subangular blocky structure; firm; common very fine roots; common discontinuous distinct brown (10YR 4/3) organic coatings on faces of peds; few discontinuous distinct brown (7.5YR 4/2) clay films on faces of peds; 2 percent pebbles; neutral; clear smooth boundary.

(Combined thickness of the Bt horizons is 15 to 40 inches.)

BCt--33 to 45 inches; yellowish brown (10YR 5/4) silty clay loam; weak medium platy structure parting to weak medium subangular blocky; firm; few very fine roots; few discontinuous distinct brown (7.5YR 4/4) clay films on faces of peds; common discontinuous distinct grayish brown (10YR 5/2) carbonate coatings on faces of peds; very few discontinuous distinct light gray (10YR 7/1) carbonate coatings in old root channels; few medium prominent strong brown (7.5YR 5/8) masses of iron accumulation in the matrix; few discontinuous distinct light gray (10YR 7/1) carbonate threads and accumulations in the matrix; 5 percent limestone and shale pebbles; strongly effervescent; moderately alkaline; gradual wavy boundary. (5 to 20 inches thick)

Cd--45 to 80 inches; brown (10YR 5/3) silty clay loam; massive with weak coarse platy partings; very firm; common continuous distinct light gray (10YR 7/2) carbonate coatings on vertical partings; common continuous faint grayish brown (10YR 5/2) iron depletions on vertical partings; common discontinuous distinct very dark grayish brown (10YR 3/2) masses of iron and manganese accumulation on vertical partings; few medium prominent strong brown (7.5YR 5/8) masses of iron accumulation in the matrix; 5 percent limestone and shale pebbles; strongly effervescent; moderately alkaline.

TYPE LOCATION: Delaware County, Ohio; Scioto Township; about 6 miles west of Delaware; 550 feet north and 1,000 feet west of the intersection of US36 and OH257; Ostrander, Ohio quadrangle; lat. 40 degrees 16 minutes 24.4 seconds N. and long. 83 degrees 09 minutes 50.5 seconds W., NAD 27.

RANGE IN CHARACTERISTICS: Depth to the base of the argillic horizon and solum thickness range from 24 to 50 inches in uneroded pedons and from 10 to 24 inches in eroded and severely eroded pedons. The depth to the top of the argillic horizon is 2 to 10 inches. Depth to densic contact typically is greater than 40 inches but is as shallow as 24 inches in eroded and severely eroded pedons. Depth to bedrock is greater than 60 inches. The depth to carbonates typically is 20 to 40 inches but ranges from 0 to 45 inches. Rock fragments are dominantly limestone and crystalline rocks. The particle-size control section averages 35 to 50 percent clay and 10 to 45 percent sand.

The Ap or A horizon has value of 2 to 4 (6 or more dry) and chroma of 2 or 3. Some severely eroded pedons have chroma of 4. The Ap or A horizon is silt loam or silty clay loam. Rock fragment content rages from 0 to 10 percent. They range from strongly acid to neutral. Some severely eroded pedons are slightly alkaline and some contain carbonates.

Some pedons have an E or BE horizon.

The Bt horizon has hue of 7.5YR or 10YR, value of 4 or 5, and chroma of 4 to 6. It is silty clay loam, clay loam, silty clay, or clay. Rock fragment content ranges from 0 to 10 percent. It ranges from strongly acid to slightly acid in the upper part unless eroded and from slightly acid to moderately alkaline in the lower part and contains carbonates in some pedons.

The BCt horizon has hue of 10YR, value of 4 or 5, and chroma of 2 to 4. It is silty clay loam or clay loam. Rock fragment content ranges from 0 to 10 percent. It is slightly alkaline or moderately alkaline.

The Cd horizon has hue of 10YR or 2.5Y, value of 4 or 5, and chroma of 2 to 4. It is silty clay loam or clay loam. Rock fragment content ranges from 2 to 15 percent. It is moderately alkaline and contains carbonates. The calcium carbonate equivalent ranges from 20 to 35 percent.

COMPETING SERIES: These are the Alexandria, Edom, Lairdsville, Millheim, Saylesville, Schoharie, and Twiggtown (T) soils. Alexandria soils have rock fragments of dominantly shale and sandstone. Edom soils have rock fragments of dominantly shale. Lairdsville, Millheim and Twiggtown soils have a lithic or paralithic contact within a depth of 60 inches. Saylesville soils have less than 2 percent rock fragments in the lower part of the control section. Schoharie soils have hue redder than 7.5YR in the Bt horizon.

GEOGRAPHIC SETTING: Lybrand soils are on shoulders and backslopes on dissected Wisconsin Age end moraines and ground moraines. They formed in 0 to 18 inches of loess and silty clay loam or clay loam till of high calcium carbonate content. Rock fragments are mainly limestone and crystalline. Slope ranges from 12 to 70 percent. Mean annual precipitation ranges from 31 to 42 inches, and mean annual temperature ranges from 46 to 54 degrees F.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Blount, Glynwood, Morley, and Pewamo soils. The somewhat poorly drained Blount and the moderately well drained Glynwood and Morley soils are either on slightly higher lying summits of the till plain or lower lying areas of moraines. The very poorly drained Pewamo soils are in slight depressions.

DRAINAGE AND PERMEABILITY: Well drained. The depth to an intermittent perched water table is 3.5 to 6 feet between February and April in most years. Permeability is slow. The potential for surface runoff is medium to very high.

USE AND VEGETATION: Most areas are used for hayland and woodland. Some areas are cultivated. Corn, soybeans, and small grains are the main crops. Native vegetation is mixed hardwoods.

DISTRIBUTION AND EXTENT: Mainly Indiana, Michigan, and Ohio, and a smaller extent in Illinois and Wisconsin. MLRA's 95B, 97, 98, 108, 110, 111. The series is of moderate extent.

MLRA OFFICE RESPONSIBLE: Indianapolis, Indiana.

SERIES ESTABLISHED: Delaware County, Ohio, 1996.

REMARKS: The Lybrand series was formerly considered a part of the Morley series. The subsequent relocation of the Morley series type location to MLRA 111 and narrowing of the series concept has resulted in the Lybrand series. The Lybrand series reflects soils that have slopes greater than 12 percent and are well drained.

Diagnostic horizons and features recognized in this pedon are: ochric epipedon - 0 to 9 inches; argillic horizon - 9 to 33 inches; densic contact - 45 inches.

Supporting laboratory data is needed to confirm the presence of densic materials in the Cd horizon.

ADDITIONAL DATA: Laboratory characterization data is available for DL-57, the typical pedon.
