TYPE LOCATION: Orange County, Vermont, Town of Bradford; about 1,000 feet north of the Bradford Center School; east side of knoll, 25 feet from top of knoll, 100 feet west of woods, East Corinth, VT topographic quadrangle; Latitude 44 degrees, 00 minutes, 55 seconds N. and Longitude 72 degrees, 10 minutes, 08 seconds W., NAD 1927.
RANGE IN CHARACTERISTICS: The thickness of the solum ranges from 14 to 40 inches. Depth to bedrock is greater than 60 inches. Rock fragments range from 0 to 5 percent. The dominant textures throughout the soil are very fine sandy loam, silt loam, and silt. Fine sandy loam, loamy very fine sand, and very fine sand are allowed in the lower part of the substratum. Thin strata of coarser and finer textured material are common in the lower part of the solum and the substratum of some pedons. Reaction ranges from strongly acid to slightly alkaline.
The Ap horizon has hue of 10YR or 2.5Y, value of 3 through 5, and chroma of 2 or 3. Some pedons have an A horizon. Some pedons have a thin E horizon.
The upper part of the Bw horizon has hue of 7.5YR through 5Y, value of 4 or 5, and chroma of 3 through 6. The lower part of the Bw has hue of 10YR through 5Y, value of 4 through 7, and chroma of 2 through 8. Some pedons have a BC horizon.
The C horizon is neutral or has hue of 10YR through 5Y, value of 3 through 6, and chroma of 2 through 6.
COMPETING SERIES: There are no other series in the same family.
The Allard, Amboy, Belgrade, Buxton, Canaseraga, Enfield, Hadley, Salmon, Scio, Timula, and Unadilla series are in related families. The Allard and Enfield soils have sandy material within a depth of 40 inches. Amboy and Canaseraga soils have a fragipan. Belgrade and Scio soils have mottles with chroma of 2 or less within 24 inches. Buxton soils have clayey textures in the lower part of the control section and are mottled in the upper 24 inches and have a frigid soil temperature regime. Hadley soils have an irregular decrease in organic matter with depth and have base saturation Less than 60 percent throughout the upper 30 inches. Salmon soils have a spodic horizon and are frigid. Timula soils are calcareous within 40 inches of the surface. Unadilla soils have base saturation less than 60 percent throughout the upper 30 inches.
GEOGRAPHIC SETTING: The Hartland soils are nearly level to very steep soils on terraces and glacial lake plains. They are on broad plains and on the tops and side slopes of hills, ridges, and knolls. Slope ranges from 0 to 50 percent. The soils formed in silty eolian or glaciolacustrine deposits. Mean annual precipitation ranges from 26 to 50 inches and the mean annual temperature ranges from 45 to 52 degrees Fahrenheit. The frost free season ranges from 105 to 180 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the moderately well drained Belgrade, the poorly and very poorly drained Canandaigua, and the poorly drained Raynham soils on nearby landscapes. The Agawam, Merrimac, and Windsor soils, on similar terrace positions, have sandy and gravelly textures. The Boxford, Munson, and Scitica soils, occupy similar landscapes, and have clayey textures in the lower part of the control section. The Hadley, Limerick, Occum, Pootatuck, Rippowam, and Winooski soils are on adjacent flood plains.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained. The potential for surface runoff is low to high. Saturated hydraulic conductivity is moderately high or high throughout the mineral soil.
USE AND VEGETATION: Most of the areas of less than 15 percent slope are used for hay, pasture, and corn. Some areas are used for potatoes, sweet corn, vegetables, tobacco, and other cash crops. Most areas of more than 15 percent slope are wooded. Common trees are white pine, white oak, red oak, black oak, sugar maple, hickory, ash, black birch, yellow birch, and white birch, beech, and hemlock.
DISTRIBUTION AND EXTENT: Vermont and eastern New York and possibly Maine, Massachusetts, and New Hampshire. MLRA 101, 141, 142, 143, 144A, 144B, and 145. The series is of moderate extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Amherst, Massachusetts
SERIES ESTABLISHED: Grafton County, New Hampshire, 1936.
REMARKS: This revision reflects new horizon designations and general updating.
This is a mesic soil series and its continued use in MLRA's 141, 143, and 144B and the state of Maine are doubtful. Also, it is doubtful it will be retained in the Connecticut state-wide update. For the present time these references are shown until areas of past use are updated.
The horizons and features diagnostic for the typical pedon are:
1. Ochric epipedon from 0 to 6 inches.
2. Cambic horizon from 6 to 19 inches.
3. Base saturation by Ammonium Acetate is greater than 60 percent in some subhorizon between the depths of 10 to 30 inches below the soil surface.
4. Carbonates are not present within a depth of 40 inches from the soil surface.
5. Particle size control section from 10 to 40 inches, is coarse-silty.
6. Mesic soil temperature regime.
7. Udic soil moisture regime.
ADDITIONAL DATA: NSSL laboratory data is available for the following pedon - S70VT-9-3
