OTEGO SERIES
The Otego series consists of very deep, moderately well drained soils formed in post-glacial alluvium derived mainly from regolith containing sandstone, siltstone, and shale and are on flood plain steps on flood plains near till plateaus and glacial outwash terraces. Permeability is moderate in the solum and upper substratum, and moderate or moderately rapid in the lower substratum. Slope ranges from 0 to 3 percent. Mean annual temperature is about 49 degrees F., and mean annual precipitation is about 37 inches.
TAXONOMIC CLASS: Coarse-silty, mixed, superactive, mesic Fluvaquentic Dystrudepts
TYPICAL PEDON: Otego silt loam, on a 1 percent slope in a cornfield. (Colors are for moist soil unless otherwise noted.)

USGS Oneonta, NY topographic quadrangle; Latitude 42 degrees, 25 minutes, 54 seconds N. and Longitude 75 degrees, 07 minutes, 10 seconds W., NAD 1927.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 24 to 48 inches. Depth to bedrock is greater than 60 inches. Rock fragments range from 0 to 5 percent in the surface layer and subsoil, from 0 to 15 percent in the substratum above 40 inches, and from 0 to 50 percent below 40 inches. Rock fragments are dominantly gravel and cobbles. Unless limed, reaction ranges from very strongly acid to slightly acid in the surface layer, subsoil, and in the upper part of the substratum; and from strongly acid to neutral in the lower part of the substratum.
The Ap or A horizon has hue of 7.5YR to 2.5Y, value of 2 to 4 (6 or 7 dry), and chroma of 1 to 4. Texture is loam, silt loam, or very fine sandy loam. Structure is weak or moderate, fine to coarse, granular or subangular blocky. Consistence is friable or very friable.
In some pedons a thin E horizon is present with hue of 7.5YR to 2.5Y, value of 5 or 6, and chroma of 2 or 3. Texture is silt loam or fine sandy loam. Structure is granular, platy, or subangular blocky. Consistence is friable or very friable.
The Bw horizon has hue of 7.5YR to 2.5Y, value of 4 to 6, and chroma of 2 to 6. Iron depletions are present in some part between a depth of 12 to 24 inches with chroma of 2 or less. Texture is silt loam or very fine sandy loam. Structure is weak or moderate, fine to coarse, subangular blocky or weak very coarse prismatic. Consistence is friable or very friable.
Some pedons have a BC horizon with hue of 10YR or 2.5Y, value of 4 to 6, and chroma of 1 to 6. Texture is silt loam or very fine sandy loam. In some pedons thin strata of fine sandy loam or loamy fine sand are below 40 inches. Structure is weak, coarse or very coarse, subangular blocky, or is massive. Consistence is friable or very friable.
The C horizon, if present, has hue of 7.5YR to 5Y, value of 4 to 6, and chroma of 1 to 8. Texture is silt loam, loam, or very fine sandy loam. In some pedons thin strata of fine sandy loam or loamy fine sand are below 40 inches. Consistence is very friable or friable.
The 2C horizon, if present, is massive or single grained with hue of 7.5YR to 5Y, value of 4 to 6, and chroma of 1 to 8, or it is multicolored. Texture ranges from loam to very gravelly loamy sand and, in some pedons, is stratified. Consistence is loose to friable, and non-sticky and non-plastic.
COMPETING SERIES: There are no other series in the same family.
Arkaqua,
Bash,
Basher,
Codorus,
Cornish,
Hamplain,
Lovewell,
Pootatuck,
Philo, and
Rowland series are similar soils in related families. Arkaqua, Codorus, and Rowland soils have fine-loamy particle size control sections. Cornish and Lovewell soils are frigid. Bash, Basher, Pootatuck, and Philo soils have coarse-loamy particle size control sections. Hamplain soils do not have low chroma mottles within 24 inches of the soil surface.
GEOGRAPHIC SETTING: Otego soils formed in post-glacial alluvium derived mainly from regolith containing sandstone, siltstone, and shale and are on flood plain steps on flood plains near till plateaus and glacial outwash terraces. Slope ranges from 0 to 3 percent. Mean annual temperature ranges from 46 to 52 degrees F., mean annual precipitation ranges from 29 to 45 inches, and mean annual frost-free days ranges from 105 to 198 days. Elevation ranges from 570 to 1300 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Bath,
Chenango,
Hamplain,
Mardin,
Scio,
Trestle,
Tunkhannock,
Unadilla,
Valois,
Wakeville and
Wayland soils. Otego soils are the moderately well drained member of a drainage sequence that includes the well drained Hamplain soils, the somewhat poorly drained Wakeville soils, and the poorly drained and very poorly drained Wayland soils. Well drained and somewhat excessively drained Chenango and Tunkhannock soils are on nearby glacial outwash terraces. Unadilla and Scio soils are on adjacent higher lacustrine or old alluvial terraces and plains. Well drained Trestle soils are on adjacent floodplain areas that are gravelly in the subsoil and substratum. Bath, Mardin, and Valois soils are on nearby till uplands.
DRAINAGE AND PERMEABILITY: Moderately well drained. The potential for surface runoff is negligible to low. Permeability is moderate in the solum and upper substratum, and moderate or moderately rapid in the lower substratum. Depth to an
intermittent apparent seasonal high water table ranges from 1.5 to 2.0 feet from December to April in normal years. Otego soils are subject to frequent flooding.
USE AND VEGETATION: Most areas are cleared and are used for growing corn for silage, small grains, hay, and pasture. A few areas have reverted to woodland or brush. Native vegetation is sugar maple, white ash, and willows. Brushy areas often contain dogwoods, willows, spirea, Hawthorne (thorn apple), and poplar.
DISTRIBUTION AND EXTENT: Central and southern New York, northeastern Ohio, and northwestern Pennsylvania. MLRA 101, 139, and 140. The series is moderately extensive.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Amherst, Massachusetts.
SERIES ESTABLISHED: Oneida County, New York, 1993.
REMARKS: This series is the low base saturation equivalent of the Teel series.
Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon - the zone from the surface to 13 inches (Ap horizon).
Cambic horizon - the zone from 13 to 35 inches (Bw1 and Bw2 horizons).
Aquic subgroup - evidenced by low chroma mottles within 24 inches of the soil surface (Bw1 horizon) Udic moisture regime.
This revision reflects a change in taxonomic classification from Coarse-silty, mixed, mesic Fluvaquentic Dystrochrepts to Coarse-silty, mixed, superactive, mesic Fluvaquentic Dystrudepts due to updates contained in the 8th Edition of Keys to Soil Taxonomy. Competing series may change as similar soils are reclassified.
Soils mapped as Chagrin silt loam, classified as Fine- loamy, mixed, mesic Dystric Fluventic Eutrochrepts, and as Lobdell silt loam, classified as Fine-loamy, mixed, mesic Fluventic Eutrochrepts in the Soil Survey of Ashtabula County, Ohio, published 1973, were correlated to the Otego series during the modernization project of that survey.
ADDITIONAL DATA: Cornell University Soil Survey Laboratory base saturation data is available for this pedon (84-29), and other pedons from Otsego County, New York. Characterization data is available from Ashtabula County, Ohio.
