DANNEMORA SERIES


Dannemora soils are very deep, poorly drained soils formed in loamy till. They are in low areas on till plains and between drumlins. They have a fragipan. Saturated hydraulic conductivity in the mineral material is moderately high to high above the fragipan and low through moderately high in the fragipan and substratum. Slope ranges from 0 through 8 percent. Mean annual temperature is 6 degrees C. and mean annual precipitation is 1476 mm.

TAXONOMIC CLASS: Coarse-loamy, mixed, active, frigid Aeric Fragiaquepts

TYPE LOCATION: Lewis County, New York; Town of Osceola, It is along a logging trail off Camp Four Road about 2 miles south of intersection with Michigan Mills Road. 0.5 miles west on logging trail; USGS North Osceola, NY topographic quadrangle, Latitude 43 degrees, 34 minutes, 32.4 seconds N. and Longitude 75 degrees, 37 minutes, 48.3 seconds W. NAD 1983.

RANGE IN CHARACTERISTICS: Solum thickness ranges from 45 to 150 centimeters. Depth to bedrock is greater than 152 centimeters. Depth to the top of the fragipan ranges from 30 to 55 centimeters. Rock fragment content ranges from 1 to 40 percent, by volume, in the mineral solum above the fragipan and from 20 to 70 percent in the fragipan and substratum. Rock fragments are dominantly gravel and channers, but also include some cobbles and stones.

O horizons, where present, are composed of fibric, hemic, or sapric material. Reaction ranges from ultra acid to moderately acid.

Some pedons have an Ap horizon with hue of 7.5YR through 2.5Y, value of 2 through 3 and chroma of 1 or 2. In uncultivated areas, A horizons may be present and have colors similar to the Ap horizon, except chroma ranges from 0 through 2. Texture ranges from silt loam through sandy loam in the fine-earth fraction. Reaction ranges from extremely acid through slightly acid.

The Eg horizon has hue of 7.5YR through 2.5Y, value of 4 through 6 and chroma of 1 or 2. Texture is silt loam through sandy loam in the fine earth fraction. Structure is subangular blocky or platy, or the material is massive. Reaction ranges from extremely acid through slightly acid. In some pedons, the E horizon is replaced by a B or BE horizon in part or in total.

The Bg horizon has hue of 7.5YR through 2.5Y, value of 3 through 5, and chroma of 1 or 2. Texture is similar to the E horizon. Structure is subangular blocky, or the horizon is massive. Reaction ranges from extremely acid to slightly acid.

The Bx horizon has hue of 5YR through 2.5Y, value of 3 through 5 and chroma of 2 or more. Texture ranges from silt loam through sandy loam in the fine-earth fraction. Reaction ranges from very strongly acid through neutral. Some pedons have a 2Bx horizon.

The C horizon has hue of 5YR through 2.5Y, value of 3 through 5 and chroma of 2 through 4. Texture ranges from loam to loamy fine sand in the fine-earth fraction. It is massive and may have plate-like divisions. Reaction ranges from very strongly acid through neutral. Some pedons have a 2C horizon.

COMPETING SERIES: There are no other series in the same family.

Similar soils in related families are the Erie, Camroden, Dalton, Marcy, Morris, Norchip, Ontusia, Rexford, Scriba, Shohola, Trussel, Volusia, Wallington, and Wiscoy series. The Camroden, Dalton, Erie, Marcy, Norchip, Ontusia, Shohola, Trussel, Volusia, Wallington, and Wiscoy soils have a different textural class. Dalton, Erie, Morris, Rexford, Scriba, Shohola, Volusia, Wallington, and Wiscoy soils are mesic. Marcy soils do not allow a chroma of greater than 2 between 15 and 75 cm of the mineral surface. Trussel soils are semiactive.

GEOGRAPHIC SETTING: Dannemora soils developed in till derived principally from sedimentary material, and some crystalline eratics. Slope ranges from 0 through 8 percent. Mean annual precipitation ranges from 762 through 1727 mm, mean annual temperature ranges from 1 through 11 degrees C, and the frost-free season ranges from 90 through 140 days. Elevation ranges from 45 through 610 meters above sea level.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Adams, Colton, Croghan, Duane, Empeyville, Fishcreek (T), Highmarket (T), Naumburg, Swancott (T), Tughill, Westbury, and Worth soils. Adams, Croghan, Fishcreek (T), and Naumburg soils developed in nearby sandy deltaic deposits. Colton, Duane, and Swancott (T) soils developed in gravelly glacial outwash. Well drained Worth, moderately well drained Empeyville, somewhat poorly drained Westbury, and very poorly drained Tughill soils are drainage associates of Dannemora soils. Highmarket (T) soils are well drained and do not have a fragipan. Tughill soils do not have a fragipan.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Poorly drained. The potential for surface runoff is low through very high. Saturated hydraulic conductivity in the mineral material is moderately high or high above the fragipan and low through moderately high in the fragipan and substratum.

USE AND VEGETATION: Some areas that are drained are used for hay and pasture. Wooded areas support red maple, elm, ash, fir, hemlock, spruce, and white pine.

DISTRIBUTION AND EXTENT: Northern New York. MLRA 141 and 142. The series is of small extent.

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

SERIES ESTABLISHED: Orange County, New York, 1954.

REMARKS: 1. This series was previously classified as Typic Fragiaquepts, but field data (colors and redoximorphic features) suggest it is Aeric.

2. Diagnostic horizons and other features recognized in the typical pedon are:
Ochric Epipedon - the zone from the surface through 18 cm (Oa, Eg, and part of Bg1 horizon).
Cambic horizon - the zone from 11 through 47 cm (part of Bg1 and Bg2 horizon).
Fragipan - the zone from a depth of 47 through 76 cm (Bx horizon).
Aquepts - as evidenced low chroma matrix colors and redoximorphic features within a depth of 50 cm from the mineral surface (Eg and Bg horizons).
Aeric subgroup - as evidenced by the matrix color at 47 cm (Bx horizon)
