LOCATION WEIDER VTEstablished Series
TAXONOMIC CLASS: Coarse-loamy over sandy or sandy-skeletal, mixed, active, frigid Fluvaquentic Dystrudepts
TYPICAL PEDON: Weider very fine sandy loam, on a one percent south-facing slope in a hay field. (Colors are for moist soil unless otherwise noted.)
Ap--0 to 6 inches; dark grayish brown (2.5Y 4/2) very fine sandy loam, light brownish gray (2.5Y 6/2) dry; weak fine granular structure; friable; many very fine and common fine roots; moderately acid; clear smooth boundary. (6 to 10 inches thick)
Bw1--6 to 18 inches; olive brown (2.5Y 4/4) very fine sandy loam, weak fine granular structure; friable; common very fine and fine roots; strongly acid; clear smooth boundary.
Bw2--18 to 25 inches; olive brown (2.5Y 4/4) very fine sandy loam; weak fine granular structure; friable; common very fine and fine roots; many medium distinct light brownish gray (2.5Y 6/2) iron depletions and many medium faint dark yellowish brown (10YR 4/4) masses of iron accumulation; strongly acid; abrupt wavy boundary. (Combined thickness of the Bw horizon is 8 to 30 inches thick.)
2Cl--25 to 38 inches; olive brown (2.5Y 4/4) loamy sand; massive; friable; few very fine roots; many fine and medium gray prominent (10YR 5/1) iron depletions and reddish brown (5YR 4/4) masses of iron accumulation; very strongly acid; clear wavy boundary. (0 to 24 inches thick)
2C2--38 to 42 inches; grayish brown (2.5Y 5/2) sand; massive; loose; many medium prominent dark brown (7.5YR 4/4) masses of iron accumulation; 1 percent rock fragments; very strongly acid; clear wavy boundary. (0 to 24 inches thick)
2C3--42 to 65 inches; olive (5Y 5/3) very gravelly sand; single grain; loose; 40 percent rock fragments; very strongly acid.
TYPE LOCATION: Washington County, Vermont; Town of Waterbury, 3000 feet northeast of the junction of Vermont 100 and Guptill Road and 200 feet east of Guptill Road. Latitude 44 degrees 21 minutes 15 seconds N., longitude 72 degrees 44 minutes 12 seconds W., NAD27.
RANGE IN CHARACTERISTICS: Thickness of the solum and depth to contrasting material ranges from 18 to 36 inches. Depth to bedrock is more than 60 inches. Reaction ranges from very strongly acid to moderately acid. Rock fragments are mostly gravel and range from 0 to 10 percent in the solum and 0 to 50 percent in the substratum.
The Ap horizon has hue of 10YR or 2.5Y, value of 3 or 4, and chroma of 1 to 3. It is silt loam, very fine sandy loam, or fine sandy loam.
The Bw horizon has hue of 2.5Y or 5Y, value of 3 to 5, and chroma of 2 to 4. It is silt loam, very fine sandy loam, or fine sandy loam. Redox depletions with a chroma of 2 or less are above a depth of 24 inches.
The 2C horizon has hue of 2.5Y or 5Y, value of 4 or 5, and chroma of 1 to 4. It is loamy fine sand, loamy sand, sand, or coarse sand in the fine-earth fraction.
COMPETING SERIES: There are no other series in the same family. The Cornish, Lovewell, Podunk and Waitsfield soils are in related families. Cornish and Lovewell soils have a coarse-silty particle-size control section. Waitsfield soils do not have redoximorphic features.
GEOGRAPHIC SETTING: Weider soils are on nearly level floodplains. Slope ranges from 0 to 3 percent. They formed in loamy alluvium overlying sandy alluvium. Mean annual precipitation ranges from 30 to 50 inches, and the mean annual temperature ranges from 42 to 46 degrees F. The frost-free season ranges from 105 to 160 days. Elevation ranges from 90 to 1200 feet above mean sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Sunday, sunny, and Waitsfield soils. The excessively drained Sunday soils are adjacent to rivers and streams. The poorly drained sunny soils are in depressions and drainageways on the floodplain. The well drained Waitsfield soils are in slightly higher positions on the floodplain.
DRAINAGE AND PERMEABILITY: Moderately well drained. Permeability is moderate in the solum and rapid in the substratum.
USE AND VEGETATION: Most areas are cleared and used for silage corn, hay, and pasture. A few areas are wooded. Common trees are eastern white pine and red pine.
DISTRIBUTION AND EXTENT: Vermont. The series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Amherst, Massachusetts.
SERIES ESTABLISHED: Washington County, Vermont, 1996.
REMARKS: 1. The classification is updated with this revision to Coarse-loamy over sandy or sandy-skeletal, mixed, active, frigid Fluvaquentic Dystrudepts. The former classification was Coarse-loamy over sandy or sandy-skeletal, mixed, frigid Fluvaquentic Dystrochrepts. 2. The Weider soils were previously included with Podunk soils in Vermont. 3. Diagnostic horizons and features recognized in this pedon are:
a. Ochric epipedon - the zone from 0 to 6 inches (Ap horizon).
b. Cambic horizon - the zone from 6 to 25 inches (Bw horizon).
c. Fluvaquentic Dystrochrepts feature - base saturation (by ammonium acetate) is less than 60 percent in all subhorizons between the depths of 10 to 30 inches below the soil surface; and the organic carbon content decreases irregularly with depth or remains more than 0.2 percent to a depth of 50 inches; and redox depletions with chroma of 2 or less are within 24 inches of the surface.
d. Strongly contrasting particle-size class - the transition between the coarse-loamy material and the underlying sandy or sandy-skeletal material is less than 5 inches thick. The loamy material has less than 50 percent fine or coarse sand.
