Established Series


Barre soils typically have a very dark gray silt loam Ap horizon, gray and weak red silty clay B2tg horizons over a reddish brown gravelly loam IIC horizon.

TAXONOMIC CLASS: Fine, illitic, mesic Udollic Endoaqualfs

TYPICAL PEDON: Barre silt loam - hay (Colors are for moist soil unless otherwise noted.)

Ap--0 to 8 inches; very dark gray (10YR 3/1) silt loam, gray (10YR 5/1) dry; moderate medium and coarse granular structure; friable; many fine roots; neutral; abrupt smooth boundary. (6 to 10 inches thick)

B21tg--8 to 12 inches; gray (10YR 5/1) silty clay; common medium distinct yellowish brown (10YR 5/6) mottles; moderate medium angular blocky structure; firm; common roots; common pores; grayish brown (10YR 5/2) ped surfaces; thin patchy clay films on ped faces, thick clay linings in pores; neutral; clear wavy boundary. (3 to 10 inches thick)

B22tg--12 to 25 inches; weak red (2.5YR 5/2) silty clay; common medium and coarse distinct strong brown (7.5YR 5/6) and common medium prominent greenish gray (5GY 6/1) mottles; moderate coarse prismatic structure that parts to moderate medium angular blocky structure; firm; common roots; common pores; thick clay linings in pores; neutral; clear smooth boundary. (10 to 20 inches thick)

IIC--25 to 50 inches; reddish brown (5YR 5/3) gravelly loam; common medium and coarse distinct strong brown (7.5YR 5/6) and few medium distinct light gray (N/7 ) mottles; massive; firm; few roots in top 10 inches; 15 percent coarse fragments; calcareous; moderately alkaline.

TYPE LOCATION: Orleans County, New York; Town of Barre, 3/5 mile north of Oak Orchard Road, 200 feet west of Amgevine Road.

RANGE IN CHARACTERISTICS: Solum thickness ranges from 20 to 40 inches. Volume of coarse fragments ranges from none to 5 percent in the solum and from 5 to 30 percent in the IIC horizon. The soil ranges from strongly acid to neutral in the solum and is slightly acid to moderately alkaline in the IIC horizon. In some pedons the lower Bt horizon is calcareous.

The Ap horizon has hues of 5YR through 2.5Y, values of 2 or 3 moist and 4 or 5 dry, and chroma of 1 or 2. It ranges from very fine sandy loam to silty clay loam.

The B2tg horizons have hues of 2.5YR to 5Y, values of 4 through 6 and chroma of 1 through 4. Faces of peds have chroma of 0, 1 or 2. Texture ranges from heavy silty clay loam to clay with 35 to 50 percent clay. They have prismatic or blocky structure parting to blocky. Clay films range from patchy to continuous on both horizontal and vertical faces of peds.

The IIC horizon has hues of 2.5YR to 5Y, values of 3 through 5 and chroma of 2 through 4. It is loam or silt loam. It has weak or moderate platy structure or the horizon to massive.

COMPETING SERIES: These are the Beecher, Frankfort and Lakemont series in the same family. Beecher soils are silty clay loam or clay loam in the lower part of the series control section. Frankfort soils have 50 to 60 percent clay in the B2 and B3 horizons and are silty clay in the lower part of the series control section. Lakemont soils lack a lithologic discontinuity within the series control section.

The Canadice, Canadea, Churchville, Fonda, Madalin and Rhinebeck series are similar soils in related families. All except Churchville soils lack a lithologic discontinuity in the series control section. Churchville soils have surface horizons with dry color value of 6 or more.

GEOGRAPHIC SETTING: Barre soils occupy nearly level depressional areas of the lake plain whic border or are associated with areas of glacial till deposits. Slopes range from 0 to 3 percent. The soil formed in a mantle of fine and moderately fine textures lacustrine materials and underlying medium textured glacial till. Mean annual precipitation ranges from 28 to 42 inches. The average growing season ranges from 149 to 190 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Appleton, Churchville, Fonda, Kendaia, Lakemont, Madalin and Ovid soils. Appleton, Kendaia, and Ovid soils are on nearby glacial till plains. Churchvill soils are somewhat poorly drained analogues. Lakemont, Fonda and Madalin soils are on the deeper lacustrine deposits.

DRAINAGE AND PERMEABILITY: Poorly drained. Runoff is very slow; some areas are ponded. Internal drainage is very slow. Permeability is moderate in the A horizon and slow or very slow in the subsoil. Permeability of the contrasting IIC horizon is moderately slow or slow.

USE AND VEGETATION: Areas that have been cleared and drained are used for hay, pasture, small grains, and corn. Some areas are idle. Wooded areas contain red maple, white and black ash,
and swamp elm.

DISTRIBUTION AND EXTENT: Ontario Lake plain and the Mohawk Valley of New York. These soils are moderately extensive.


SERIES ESTABLISHED: Orleans County, New York, 1973.

REMARKS: Soils that fit within the concept of the Barre series were previously recognized as inclusions in mapping of Madalin and Lakemont soils.
