WEYERS SERIES

The Weyers series consists of very deep, very poorly drained soils formed in 102 to 152 cm (40 to 60 inches) of material weathered from calcareous tufa and underlain by lacustrine sediments on lake plains. These soils occur near spring orifices and seepage areas of calcium carbonate charged water. Slope ranges from 0 to 1 percent. Mean annual precipitation is about 838 mm (33 inches), and mean annual air temperature is about 11 degrees C (51 degrees F).

TAXONOMIC CLASS: Coarse-loamy, carbonatic, mesic Fluvaquentic Endoaquolls

TYPICAL PEDON: Weyers silt loam, on a broad, nearly level area in a cultivated field at an elevation of 189 meters (620 feet) above mean sea level. (Colors are for moist soil unless otherwise stated.)

3Cg2--137 to 203 cm (54 to 80 inches); grayish brown (10YR 5/2) silty clay loam; massive; firm; few very fine roots; common medium prominent strong brown (7.5YR 5/6) and brown (7.5YR 4/4) masses of iron accumulation in the matrix; few fine black (10YR 2/1) iron and manganese oxide concretions; strongly effervescent; moderately alkaline.

TYPE LOCATION: Erie County, Ohio; about 2 miles northwest of Castalia, in Margaretta Township; approximately 1,700 feet east of the intersection of Oxbo Road (Township Road 34) and Northwest Road (County Road 6) along Oxbo Road (Township Road 34), then 550 feet south; Quadrangle 3; T. 6 N., R. 24 W.; USGS Castalia, Ohio topographic quadrangle; lat. 41 degrees 23 minutes 25 seconds N. and long. 82 degrees 50 minutes 25 seconds W., NAD 27.

COMPETING SERIES: There are no other series in this family. The Sandusky series is in a related family. The Sandusky soils average between 18 and 27 percent clay in the particle-size control section and are underlain by lacustrine sediments at a depth of 51 to 102 cm (20 to 40 inches).

GEOGRAPHIC SETTING: Weyers soils are on broad, nearly level lake plains adjacent to subterranean springs or seepage areas with calcium carbonate charged water that flowed or are flowing from limestone. Slope ranges from 0 to 1 percent. The soils formed in 102 to 152 cm (40 to 60 inches) of calcareous tufa and are underlain by lacustrine sediments. Mean annual precipitation ranges from 813 to 864 mm (32 to 34 inches). Mean annual air temperature ranges from 10 to 11 degrees C (50 to 52 degrees F).

GEOGRAPHICALLY ASSOCIATED SOILS: These are the very poorly drained Sandusky, Lenawee, and Toledo soils. Lenawee and Toledo soils lack a mollic epipedon and formed in lacustrine sediments. They are on similar topographic positions on the lake plain but do not have the overlying calcareous material weathered from tufa. Sandusky soils are underlain by moderately fine textured lacustrine sediments at a depth of 51 to 102 cm (20 to 40 inches) and are further from the subterranean springs than Weyers soils.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Very poorly drained. The depth to the top of an intermittent perched high water table ranges from the surface to 15 cm (0.5 foot) between November and June in normal years. The potential for surface runoff is negligible. Saturated hydraulic conductivity is high in the tufa material and moderately low in the lacustrine material. Permeability is moderately rapid in the tufa material and moderately slow or slow in the lacustrine material.

USE AND VEGETATION: Some areas are cultivated. Corn and soybeans are the principal crops. Many areas are used for wildlife habitat. Native vegetation is reeds and grass with scattered willows and red cedar.

DISTRIBUTION AND EXTENT: Northern Ohio; MLRA 99. The series is of small extent, about 3000 acres.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: AMHERST, MASSACHUSETTS

SERIES ESTABLISHED: Sandusky County, Ohio, 1983.

REMARKS: The 03/1999 revision moves the type location from Sandusky County, Ohio to Erie County, Ohio. Review of documentation from Sandusky and Erie County supports the redefinition of the series concept.

Weyers soils do not have a calcic horizon because they are not enriched by secondary pedogenic carbonates. They have an irregular decrease in organic carbon but are not on flood plains and do not flood from stream overflow. The darker layers were buried by the accumulation of calcareous tufa. Weyers soils were formerly included with the Warners series.

Diagnostic horizons and features recognized in this pedon are:
Mollic epipedon: from the surface to a depth of 33 cm (Ap horizon).
Aquic conditions: from the surface to a depth of 203 cm.
