CANFIELD SERIES


The Canfield series consists of very deep, moderately well drained soils formed in Wisconsinan age till on plains. In some pedons there is a thin loess mantle. Saturated hydraulic conductivity is moderately high above the fragipan and moderately low in the fragipan and substratum. Slope ranges from 0 to 35 percent. Mean annual precipitation is about 1065 mm (42 inches), and mean annual temperature is about 9 degrees C (48 degrees F).

TYPE LOCATION: Holmes County, Ohio; Salt Creek Township, about 2.8 miles north of Mt. Hope; about 1055 feet south and 2375 feet west of the northeast corner of section 26, T. 15 N., R. 12 W.; USGS Fredericksburg, Ohio topographic quadrangle; Latitude 40 degrees, 39 minutes, 56 seconds N. and Longitude 81 degrees, 47 minutes, 34 seconds W., NAD 1983.

RANGE IN CHARACTERISTICS: Thickness of the solum ranges from 102 to 152 cm (40 to 60 inches), but may be thinner on eroded pedons. Depth to the top of the fragipan ranges from 38 to 76 cm (15 to 30 in). Depth to carbonates is 127 to 254 cm (50 to 100 in). Content of rock fragments, dominantly sandstone but including shale and some crystalline rocks, ranges from 0 to 20 percent by volume above the fragipan, 2 to 25 percent in the fragipan and 2 to 34 percent below the fragipan. Base saturation is more than 60 percent at a depth of 76 cm (30 in) below the upper boundary of the fragipan. The particle size control section averages 18 to 27 percent clay.

The Ap horizon has hue of 10YR, value of 4 or 5, and chroma of 2 or 3. Some uncultivated pedons have an A horizon 3 to 13 cm (1 to 5 inches) thick that has hue of 10YR, value of 2 or 3, and chroma of 1 or 2. The Ap or A horizon is silt loam, loam, fine sandy loam, or their gravelly analogues. Unless limed, the A or Ap horizon commonly is very strongly acid or strongly acid.

The E horizon is mixed in the Ap in some cultivated areas. Where present, the E horizon has hue of 10YR, value of 4 to 6, and chroma of 2 to 4. It is silt loam, loam, fine sandy loam, or their gravelly analogues. Unless limed, it is very strongly acid or strongly acid.

The BE horizon has hue of 10YR, value of 4 or 5, and chroma of 3 to 6. It is silt loam or loam, or their gravelly analogues. Unless limed, it is very strongly acid or strongly acid.

The Bt or 2Bt horizon has hue of 7.5YR to 2.5Y, value of 4 or 5, and chroma of 3 to 6; and redoximorphic features with chroma of 2 or less above the fragipan and within the upper 10 inches of the Bt or 2Bt. It is commonly loam or silt loam, or their gravelly analogues but thin subhorizons with clay loam or silty clay loam are in some pedons. It is very strongly acid or strongly acid.

The Btx or 2Btx horizon has hue of 7.5YR to 2.5Y, value of 4 or 5, and chroma of 3 to 6. It is loam, silt loam, sandy loam, or their gravelly analogues. It is very strongly acid to neutral.

There is a BC or 2BC horizon in some pedons that is similar to the Btx or 2BTx horizons, but is not brittle.

The C or 2C horizon has hue of 10YR or 2.5Y, value of 4 or 5, and chroma of 3 or 4. It is loam, silt loam, sandy loam or their gravelly analogues. It is strongly acid to slightly alkaline.

COMPETING SERIES: These are the Nockamixon, Rittman, Teegarden and Titusville series. The Nockamixon series has less than 60 percent base saturation at a depth of 76 cm (30 in) below the upper boundary of the fragipan. The Rittman series has 27 to 35 percent clay in the particle size control section. The Teegarden series has sola 127 to 203 cm (50 to 80 in) thick with weathered material from fractured bedrock at 102 to 152 cm (40 to 60 in). The Titusville series formed in Illinoian age till.

GEOGRAPHIC SETTING: Canfield soils formed in low-lime Wisconsinan age till on till plains. Commonly, the till is thinly mantled with loess. Slope ranges from 0 to 35 percent. Climate is humid. Mean annual precipitation ranges from 830 to 1320 mm (33 to 52 in) Mean annual temperature ranges from about 6 to 11 degrees C (43 to 52 degrees F).

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bogart, Chili, Frenchtown, Ravenna, and Wooster soils. The well drained Wooster soils, the somewhat poorly drained Ravenna soils, and the poorly drained Frenchtown soils are in a toposequence with Canfield soils. The Wooster soils are on similar positions and the Ravenna and Frenchtown soils are on lower topographic positions or are on less sloping areas along drainageways. The Bogart and well drained Chili soils are on nearby areas of gravelly outwash.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Moderately well drained. Saturated hydraulic conductivity is moderately high above the fragipan and moderately low in the fragipan and substratum. Depth to an intermittent perched seasonal high water table ranges from 25 to 53 cm (10 to 21 in) from November to April in normal years.

USE AND VEGETATION: Most areas are cultivated. Principal crops are corn, soybeans, small grain and hay. Steeper slopes are commonly in pasture or woodland. The natural vegetation is deciduous hardwood forest.

DISTRIBUTION AND EXTENT: Northeastern and north central Ohio, northwestern Pennsylvania, and in some areas in New York as of 2014 (see REMARKS). MLRAs 139 and 140. The series is extensive.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Amherst, Massachusetts

SERIES ESTABLISHED: Trumbull County, Ohio, 1917.

REMARKS: Diagnostic horizons and features recognized in this pedon include:
1. Ochric epipedon - 0 to 23 cm (0 to 9 in) (Ap, BE).
2. Argillic horizon - 23 to 114 cm (9 to 45 in) (Bt1, 2Bt2, 2Bt3, 2Btx1,2Btx2).
3. Fragipan - 66 to 114 cm (26 to 45 in) (2Btx1, 2Btx2).
4. Redoximorphic features - 15 to 114 cm (6 to 45 in).

A moderately shallow to bedrock phase has been recognized. This phase will need to be evaluated during MLRA update activities.

Canfield that was previously mapped in New York has been correlated to Mardin in survey areas that have been updated. In old survey areas in NY which haven't been updated, Canfield remains in the legend. As of 2014 a future project has been established in NASIS to investigate these areas, as well as areas in Columbia County, PA which are geographically separated from the main concentration of Canfield soils.

ADDITIONAL DATA: Characterization data for the Canfield series can be found at the NCSS KSSL Soil Characterization Database. This includes data from the Ohio State University, Columbus, Ohio.
