TYPE LOCATION: Tompkins County, New York, five miles northeast of Ithaca, 0.56 mile southeast of Highway 13 on Pine Woods Hill Road, 300 feet south of road. Elevation 1450 feet. Ithaca East, NY USGS topographic quadrangle; Latitude 42 degrees, 28 minutes, 05 seconds N. and Longitude 76 degrees, 23 minutes, 15 seconds W. NAD 1927.
RANGE IN CHARACTERISTICS: Thickness of solum and depth to bedrock ranges from 20 to 40 inches. Rock fragments are dominantly flat angular fragments and flagstones and occupy 10 to 35 percent of the volume in the Ap horizon and 20 to 60 percent in the B and C horizons, but the weighted average for the control section is less than 35 percent. Reaction is very strongly acid through neutral in the surface layer, very strongly acid through moderately acid in the subsoil and strongly acid or moderately acid in the substratum.
The Ap horizon has hue of 7.5YR through 2.5Y, value of 3 through 5, and chroma of 2 through 4. Texture of the fine-earth fraction is loam or silt loam. Structure is weak or moderate fine granular. Consistence is friable or very friable. Some pedons have thin black A horizons and reddish Bhs horizons where unplowed.
The Bw horizon has hue of 7.5YR through 2.5Y, value of 4 through 6, and chroma of 3 through 6. Texture of the fine-earth fraction is loam or silt loam. Structure is weak or moderate, very fine to medium subangular blocky or granular. Consistence is friable or very friable.
The BC horizon, if present, has colors and textures similar to the B or C horizon. It has weak subangular blocky or platy structure. Consistence is friable or firm.
The C horizon has hue of 7.5YR through 5Y, value of 3 through 6, and chroma of 2 through 4 with or without redoximorphic features. Texture of the fine-earth fraction is fine sandy loam to silt loam. It is massive or has weak plate-like divisions. Consistence is friable or firm.
The 2R layer consists of massive thick to thin beds of siltstone or sandstone interbedded with shale. The rock is jointed and is commonly fractured along joint planes within the upper 3 to 6 feet.
COMPETING SERIES: These are the Ashe, Brookfield, Buladean, Cardigan, Charlton, Chestnut, Delaware, Dutchess, Edneyville, Flatbush (T), Foresthills (T), Gallimore, Greenbelt (T), Hazel, Newport, Riverhead, Sharpcrest (T), Soco, St. Albans, Stecoah, Steinsburg, and Yalesville series in the same family. Ashe, Buladean, Chestnut, Edneyville, Gallimore, Hazel, Soco, Steinsburg, and Stecoah soils are commonly used in MLRAs outside of LRRs R and S.
Ashe soils have granite bedrock at 20 to 40 inches. Brookfield, Buladean, Chadakoin, Charlton, Chestnut, Dutchess, Edneyville, Flatbush (T), Foresthills (T), Greenbelt (T), Newport, Riverhead, and St. Albans soils are all more than 40 inches deep to bedrock. Cardigan soils have rock fragments dominated by phyllite. Delaware soils have less than 5 percent rock fragments in the solum and substratum. Hazel soils formed in Piedmont sediments derived from graywacke and phyllite containing abundant mica. Sharpcrest (T) do not have an OSD on file to compete. Soco and Stecoah soils are more than 40 inches deep to hard bedrock and formed in residuum that formed from weathered metasedimentary rocks. Steinsburg soils have sola less than 20 inches thick. Yalesville soils have 5YR or redder hue in the B and C horizons.
GEOGRAPHIC SETTING: Lordstown soils are nearly level to very steep soils with slopes ranging from 0 to 90 percent. These soils formed in till and cryoturbated material derived from siltstone and sandstone on bedrock controlled landforms of glaciated dissected plateaus. Mean annual air temperature ranges from 45 to 50 degrees F., mean annual precipitation ranges from 32 to 45 inches, and the mean frost-free season ranges from 110 to 145 days. Elevation ranges from 800 to 1800 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the very deep well drained Bath soils, the moderately deep Mardin soils, and the somewhat poorly drained Volusia soils that occupy associated deep deposits of till. Shallow somewhat excessively drained Arnot soils, and somewhat poorly drained Tuller soils, are closely associated on landforms where the soil mantle is thinner over bedrock.
DRAINAGE AND PERMEABILITY: Well drained. The potential for surface runoff is low to very high. Permeability is moderate throughout the soil.
USE AND VEGETATION: Large areas on the steep and very steep landforms are in cut-over forest, composed of American beech, oaks, sugar maple and associated species. Some cleared areas are in pasture or are used for hay, but mostly they are idle or have reverted to woodland or brush. A limited acreage is in corn and small grains. Potatoes are grown locally on undulating to sloping areas. Some areas have been reforested, mainly with red pine.
DISTRIBUTION AND EXTENT: The glaciated Allegheny Plateau of southern New York, northern Pennsylvania and Ohio, and Vermont. MLRA 100, 101, 127, 139, 140, and 142. The series is extensive.
MLRA OFFICE RESPONSIBLE: Amherst, Massachusetts
SERIES ESTABLISHED: Trumbull County, Ohio, 1914.
REMARKS: Lordstown is the mesic equivalent of Mongaup. Original classification of Lordstown placed it in the subgroup Typic Dystrochrepts, but because of changes established in the 8th edition of "Keys To Soil Taxonomy", this soil now classifies in the subgroup of Typic Dystrudepts. Competing series are expected to change as similar soils are reclassified. Diagnostic horizons and other features recognized in the typical pedon are:
(1) Ochric Epipedon - the zone from 0 to 5 inches (Ap horizon).
(2) Cambic horizon - the zone from 5 to 26 inches (Bw horizons).
(3) Udic soil moisture regime.
(4) Estimate CEC activity class to be active based on sampled pedon S91NY077-05 {another pedon S79NY105-06 was superactive}
