TYPE LOCATION: Franklin County, New York; Town of Westville, 1.55 miles southwest of Westville and 100 feet west of Fort Covington-Westville town line road opposite "T" made by road to the east. USGS Fort Covington, NY topographic quadrangle; latitude 44 degrees, 56 minutes, 32 seconds N. and longitude 74 degrees, 26 minutes, 11 seconds W. NAD 1927.
RANGE IN CHARACTERISTICS: Thickness of the solum ranges typically is 20 to 40 inches but the current correlated range includes 15 to 33 inches. Depth to carbonates ranges from 10 to 33 inches. Depth to bedrock is more than 60 inches. Rock fragments range from 3 to 35 percent in the A horizon, 5 to 35 percent in the B horizon, and 5 to 40 percent in the C horizon. Rock fragments are mainly gravel with some cobbles and stones. Some pedons have C horizons with dominant chroma of 2 above 20 inches, but the soil is not saturated for significant periods during the growing season; thus this color is due to a lithochromic effect. Values for exchangeable magnesium range from 15 to 100 percent of the values for exchangeable calcium in the B and the C horizons.
The Ap horizon has hue of 7.5YR or 10YR, value of 3 or 4, and chroma of 2 or 3. Texture is fine sandy loam, loam, or silt loam in the fine-earth fraction. The horizon has fine or medium granular structure and friable or very friable consistence. Reaction ranges from strongly acid through neutral. In undisturbed areas, pedons have an A horizon up to 5 inches thick, with a hue of 10YR or 7.5YR, value of 2 or 3, and chroma of 2.
The Bw horizon has hue of 5YR to 2.5Y, value of 4 or 5, and chroma of 3 or 4. Texture is fine sandy loam, loam, or silt loam in the fine-earth fraction. It has very weak to moderate, fine or medium subangular blocky structure and is very friable or friable. Reaction ranges from strongly acid through slightly alkaline.
Some pedons have a BC horizon with fine subangular blocky structure or platy structure, or it is massive.
The Cd horizon has hue of 10YR to 5Y, value of 4 through 6, and chroma of 2 through 4. Texture is fine sandy loam, very fine sandy loam, or loam in the fine earth fraction. The horizon is massive or has plate-like divisions. Consistence is mainly firm or very firm. Some pedons have a C horizon that is friable and up to 20 inches thick above the Cd. The Cd, or C, horizon is calcareous, but effervescence is often slow with cold dilute acid which is typical for finely divided dolomite. Reaction is slightly alkaline or moderately alkaline.
COMPETING SERIES: There are no other series in the same family.
The Amenia, Bombay, Eelweir, Georgia, Grenville, and Kalurah soils are similar soils in related families. Amenia, Bombay, and Georgia soils have a mesic temperature regime; in addition, Amenia soils have a lower content of magnesium and a high content of calcite, Bombay soils have an argillic horizon, and Georgia soils lack free carbonates within a depth of 40 inches. Eelweir and Kalurah soils lack carbonates within a depth of 40 inches. In addition, Eelweir soils have less than 5 percent rock fragments in the subsoil and substratum. Grenville soils lack 2 chroma redoximorphic depletions within a depth of 24 inches.
GEOGRAPHIC SETTING: Hogansburg soils are nearly level to moderately steep and are on glacial till plains. The till has a high component of dolomitic limestone with varying amounts of calcitic limestone, sandstone, schist and granitic materials. Slopes range from 0 to 25 percent. Mean annual temperature ranges from 42 to 45 degrees F, mean annual precipitation ranges from 30 to 42 inches, and mean annual frost-free days ranges from 110 to 160 days. Elevation range from 200 to 600 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Grenville, Kalurah, Malone, Nehasne, and Waddington soils. Grenville and Malone soils are in a drainage sequence with Hogansburg soils. The well drained Grenville soils are on high convex ridges and knolls, and somewhat poorly drained Malone soils are on foot slopes and in nearly flat areas. Kalurah soils are in nearby areas where the soil is slightly more acid. Nehasne soils are in areas where bedrock is at depths less than 40 inches. Waddington soils are on nearby terraces and formed in stratified sand and gravel deposits.
DRAINAGE AND PERMEABILITY: Moderately well drained. Runoff ranges from very slow to rapid, but is mainly medium. Saturated hydraulic conductivity is moderately high or high in the solum and moderately high in the substratum.
USE AND VEGETATION: Most areas are cleared and are used for growing hay, corn, and small grains. Some areas are pastured, in forests or brush land. Woodlots contain sugar maple, basswood, ash, hop hornbeam, red oak, elm, and butternut.
DISTRIBUTION AND EXTENT: Northwestern Connecticut, St. Lawrence lowlands and Champlain Valley of New York. MLRA 142 and 144B. The series is moderately extensive.
MLRA OFFICE RESPONSIBLE: Amherst, Massachusetts
SERIES ESTABLISHED: Franklin County, New York, 1955.
REMARKS: Competing series are expected to increase as similar soils are reclassified. Diagnostic horizons and other features recognized in the typical pedon are:
(a) Ochric Epipedon - the zone from the surface to a depth of 7 inches (Ap horizon).
(b) Cambic horizon - the zone from 7 to 20 inches (Bw horizons).
(c) Aquic Subgroup - low chroma mottles within a depth of 24 inches (Bw2 horizon).
(d) Eutrochrepts great group - free carbonates within a depth of 40 inches.
Soil Interpretation Record No. NY0215, NY0216.
