LEWBEACH SERIES


The Lewbeach series consists of very deep, well drained soils formed in till derived from sandstone, siltstone and shale. They are gently sloping to steep soils on hillsides and hilltops on uplands. A dense fragipan is present beginning at a depth of 43 to 91 cm (17 to 36 in). Saturated hydraulic conductivity is moderately high or high in the mineral soil above the fragipan and low or moderately low in and below the fragipan. Slope ranges from 3 to 55 percent. Mean annual temperature is 7 degrees C (45 degrees F) and mean annual precipitation is 1120 mm (44 in).

TYPE LOCATION: Otsego County, New York, Town of Butternuts; 1,000 feet north of the intersection of Field Miller Road and County Route 5 and 400 feet East of Field Miller Road, in a cornfield. USGS Otego, NY topographic quadrangle, Latitude 42 degrees, 27 minutes, 15 seconds N. and Longitude 75 degrees, 14 minutes, 59 seconds W. NAD83

RANGE IN CHARACTERISTICS: Thickness of the solum ranges from 102 to 183 cm (40 to 72 in) or more. Depth to bedrock is usually greater than 152 cm (60 in). Depth to the fragipan ranges from 43 to 91 cm (17 to 36 in). Rock fragment content ranges from 5 to 35 percent by volume in the A and Bw horizons and from 15 to 50 percent in the Bx and C horizons. Reaction, where unlimed ranges from very strongly acid to moderately acid in the solum, and strongly acid to slightly acid in the C horizon.

The Ap horizon has hue of 5YR to 10YR, value of 2 to 4 and chroma of 2 or 3. Dry color value is 6 or more. It is silt loam, loam or fine sandy loam in the fine earth fraction. Structure is weak or moderate granular or subangular blocky. Consistence is friable or very friable. Where an A horizon is present, thickness ranges from 5 to 10 cm (2 to 4 in).

The Bw horizon has hue or 2.5YR to 7.5YR, value of 4 or 5 and chroma of 3 to 6. It is loam, silt loam, fine sandy loam, or sandy loam in the fine earth fraction. Structure is weak to strong, medium or fine subangular blocky.

The E horizon, where present, has hue of 5YR or 7.5YR, value of 3 to 6 and chroma of 2 or 3. It is sandy loam, fine sandy loam, loam or sandy loam in the fine earth fraction. Structure is granular, platy or subangular blocky and consistence is friable or very friable.

The Bx horizon has hue of 2.5YR to 7.5YR, value of 3 to 5 and chroma of 2 to 4. It is sandy loam, fine sandy loam, loam or silt loam in the fine earth fraction. Gray or brown redoximorphic features may be present. Prism face colors range from weak red (2.5YR 5/2) to light brown (7.5YR 6/4). It has very coarse prismatic structure with platy, blocky or massive interiors.

The C or Cd horizon, where present, has color and texture similar to those of the Bx horizon.

COMPETING SERIES: The Lewbath and Willowemoc series are in the same family. Lewbath soils have hues of 7.5YR or yellower in the Bx and C horizons. Willowemoc soils have redoximorphic features in the Bw horizon below 30 cm (12 in).

GEOGRAPHIC SETTING: Lewbeach soils are gently sloping to very steep soils on glaciated uplands. Slope ranges from 3 to 55 percent. The soils developed in very firm, acid till high in sandstone with a smaller component of red shale. The climate is humid and is cool in summer and cold in winter. Annual air temperature ranges from 4 to 9 degrees C (39 to 48 degrees F). Annual precipitation ranges from 825 to 1790 mm (32 to 70 in) and the frost free days range from 110 to 155 days. Elevation ranges from 425 to 1100 m (1394 to 3608 ft) above sea level.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the moderately well drained Willowemoc, the somewhat poorly drained Onteora soils, and poorly drained Norchip soils that are associated in a drainage sequence with Lewbeach. The moderately deep Mongaup and Vly soils near hilltops and the very deep, well drained Elka soils that lack fragipans are on nearby landscapes.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained. The potential for surface runoff is low to very high. Saturated hydraulic conductivity is moderately high or high in the mineral soil above the fragipan and low or moderately low in and below the fragipan.

USE AND VEGETATION: Cleared areas are used for hay, pasture, and some corn. Many areas are forested or idle. Native trees include sugar maple, black cherry, red maple, beech, ash, birch, and hemlock.

DISTRIBUTION AND EXTENT: Higher elevations of MLRA 140. The series is moderately extensive.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Amherst, Massachusetts

SERIES ESTABLISHED: Sullivan County, N.Y., 1984.

REMARKS: Lewbeach was proposed as the frigid equivalent of Lackawanna. As defined for Sullivan County, it ranged to cover soils mapped as Swartswood in the frigid region.

Diagnostic horizons and other features recognized in the typical pedon include:
1. Ochric epipedon - from 0 to 23 cm (0 to 9 in) (Ap horizon).
2. Cambic horizon - from 23 to 48 cm (9 to 19 in) (Bw horizon).
3. Fragipan - from 69 to183 cm (27 to 72 in) (Bx1 and Bx2 horizons).
4. Udic soil moisture regime (humid, temperate climate).

ADDITIONAL DATA: Characterization data is available for 2 pedons from Delaware County, NY (S86NY025-010,011) and 1 pedon from Allegany County, NY (S10NY003002).
