TYPE LOCATION: Clinton County, New York; Town of Champlain; 400 feet east of the intersection of US Route 9 and US Route 11, about 400 feet north of Route 11, in a pasture; USGS Champlain, NY topographic quadrangle; Latitude 44 degrees, 58 minutes, 16 seconds N. and Longitude 73 degrees, 26 minutes, 43 seconds W., NAD 1927.
RANGE IN CHARACTERISTICS: The thickness of the solum ranges from 22 to 45 inches. Depth to carbonates range from 30 to 80 inches. Redoximorphic features occur within 20 inches of the mineral soil surface. Depth to bedrock is greater than 60 inches. Rock fragments range from 0 to 5 percent by volume throughout the soil.
The Ap or A horizon has hue of 10YR or 2.5Y, value of 3 or 4, and chroma of 1 to 3. It is silt loam or very fine sandy loam in the fine earth fraction. Reaction ranges from moderately acid to neutral.
The BE or BEg horizon, where present, has hue of 10YR or 2.5Y, value of 5 or 6, and chroma of 1 to 3. It is silt loam or very fine sandy loam in the fine earth fraction. Reaction ranges from moderately acid to slightly alkaline.
The Btg or Bt horizon has hue of 10YR or 2.5Y, value of 4 or 5, and chroma of 1 or 2. It is dominantly silt loam or silty clay loam in the fine earth fraction, with thin subhorizons of very fine sandy loam. Reaction ranges from moderately acid to slightly alkaline.
The BCg or BC horizon, where present, has hue of 10YR or 2.5Y, value of 4 or 5, and chroma of 1 to 3. It is very fine sandy loam, silt loam or silty clay loam in the fine earth fraction. Reaction ranges from neutral to moderately alkaline.
The Cg or C horizon has hue of 7.5YR to 2.5Y, value of 4 to 6, and chroma of 1 to 3. It is very fine sandy loam, silt loam, silty clay loam, or silty clay in the fine earth fraction. Reaction is ranges from neutral to moderately alkaline.
COMPETING SERIES: There are no currently no other series in the same family.
Boothbay, Depeyster, Muskellunge, Mino, Niagara, Swanville, Swanton, Roundabout, and Wegatchie are similar soils in related families. Boothbay and Depeyster soils have a udic moisture regime. Muskellunge soils have a fine textured particle-size class. Mino, Swanville, Swanton, Roundabout, and Wegatchie soils do not have argillic horizons. Niagara soils have a mesic temperature regime.
GEOGRAPHIC SETTING: Hailesboro soils are on lacustrine plains and lower valley walls that have a concave or slightly convex surface. The slope is commonly 1 to 4 percent, but ranges from 0 to 8 percent. The soils formed in lake deposited silts and clays. The mean annual temperature ranges from 38 to 45 degrees F. and mean annual precipitation ranges from 34 to 50 inches. The growing season ranges from 100 to 150 days. The elevation range is 300 to 2000 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Depeyster, Insula, Malone, Mino, Summerville, Swanton, and Wegatchie series. Depeyster soils are in higher positions on the landscape and do not have low chroma colors dominant in the matrix or in coatings on ped faces in the argillic horizon. Insula and Summerville soils are in higher positions on the landscape than Hailesboro soils and are shallow to bedrock. Malone soils are coarse-loamy and are on the footslopes and backslopes of hills and ridges. Mino and Swanton soils are on similar positions on the landscape as Hailesboro soils. Mino soils are coarse-loamy and Swanton soils are coarse-loamy over clayey. Wegatchie soils are in depressions and have color values in the A horizon of less than 4 moist or less than 6 dry, crushed and smoothed.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat poorly drained. The potential for surface runoff is high or very high. Saturated hydraulic conductivity in the mineral soil surface and subsurface layers is moderately high or high. It is moderately low to high in the subsoil and substratum.
USE AND VEGETATION: Most areas of Hailesboro soils have been cleared and are being used for growing hay or corn. Some areas are used for pasture or are in woodland. Native vegetation includes red maple, elm, northern red oak, white ash, and eastern hemlock.
DISTRIBUTION AND EXTENT: The St. Lawrence and Ausable River Valleys of Northern New York and the Champlain Plain of New York and possibly Vermont. MLRA 142 and 143. The series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Amherst, Massachusetts.
SERIES ESTABLISHED: St. Lawrence County, New York, 1990.
REMARKS: Type location moved (from St. Lawrence County) to better reflect the Aeric subgroup classification.
Diagnostic horizons and features recognized in this pedon are:
a. Ochric epipedon - the zone from 0 to 15 inches (Ap and BE horizons).
b. Argillic horizon - the zone from 15 to 30 inches (Btg horizon).
c. Aqualfs suborder - redoximorphic features in all layers between the bottom of the Ap and 16 inches (BE horizon and top of Btg horizon), and redoximorphic concentrations and 50 percent or more redoximorphic depletions with a chroma of 2 in the matrix within the top 4 inches of the argillic horizon (Btg horizon).
d. Aeric subgroup - one or more horizon between the Ap horizon and a depth of 30 inches, in 50 percent or more of the soil matrix, a hue of 10YR and a value and chroma of 3 or more (BE horizon).
ADDITIONAL DATA: Characterization data is available for two pedons in St. Lawrence County, New York; S82NY-89-001 and S82NY-89-002.
