TYPE LOCATION: Portage County, Ohio; Brimfield Township, about 0.5 mile south of Kent, 800 feet south of the intersection of Sunnybrook Road (County Highway 11) and Melroy Road (Township Road 92) along Sunnybrook Road, then 250 feet west. T. 2 N., R. 9 W. USGS Kent, Ohio topographic quadrangle; Latitude 41 degrees, 7 minutes, 45 seconds N. and Longitude 81 degrees, 21 minutes, 54 seconds W., NAD 1927.
RANGE IN CHARACTERISTICS: The solum thickness ranges from 30 to 60 inches. Rock fragments are typically absent, but range up to 3 percent in the BC horizon and 10 percent in the C horizon. Stratification is evident within the series control section.
The Ap horizon has hue of 10YR, value of 4 or 5, and chroma of 2 or 3. An A horizon, when present, is 1 to 4 inches thick and has hue of 10YR, value of 2 or 3, and chroma of 1 or 2. Structure is weak or moderate, very fine to medium, granular or angular blocky. Reaction ranges from very strongly acid to moderately acid. Areas that have been limed are slightly acid or neutral.
Some pedons have an E horizon that is 2 to 8 inches thick and has hue of 10YR, value of 5 or 6, and chroma of 3 or 4. Texture is silt loam. Structure is weak or moderate, fine or medium, subangular or angular blocky. Reaction ranges from very strongly acid to moderately acid.
Some pedons have a BE horizon with hue of 10YR, value of 4 or 5, and chroma of 3 to 6. Texture is silt loam. Structure is weak or moderate, fine or medium, subangular or angular blocky. Reaction ranges from very strongly acid to moderately acid. Some pedons have a B/E horizon.
The Bt horizon has hue of 7.5YR or 10YR, value of 4 or 5, and chroma of 3 to 6. Texture is silty clay loam or silt loam. Some pedons have strata of loam, very fine sandy loam or fine sandy loam. Structure is moderate or strong, fine to coarse, subangular or angular blocky, or weak, medium or coarse, prismatic, or thin to thick platy. Reaction ranges from very strongly acid to moderately acid. Some pedons have a thin layer with slight brittleness in the middle or lower part of the Bt horizons.
The BC horizon has texture of silt loam or silty clay loam, with strata of fine sandy loam in some pedons. Structure is weak, coarse subangular or angular blocky, or very coarse prismatic, or thin to thick platy. Reaction ranges from very strongly acid to neutral.
The C horizon has hue of 10YR or 7.5YR, value of 4 or 5, and chroma of 3 to 6. Texture is commonly stratified silt, silt loam, or silty clay loam. Some pedons have strata of loam, sandy loam, fine sandy loam or silty clay, or lenses of very fine sand or fine sand. Reaction ranges from very strongly acid to slightly alkaline.
COMPETING SERIES: These are the Appleriver, Blair, Bunkum, Fishhook, Freeburg, Geff, Keene, Muren, Reesville, Sugarvalley, Torox, and Xenia series. Appleriver, Keene, Muren, Reesville and Xenia soils lack stratification in the series control section. Blair, Fishhook, and Geff soils have a thicker solum. Bunkum and Freeburg soils have higher mean annual temperatures. Sugarvalley and Torox soils have carbonates within 60 inches.
GEOGRAPHIC SETTING: Glenford soils formed in stratified Wisconsinan age glaciolacustrine or stream sediments derived from materials high in sandstone and shale. Glenford soils are on summits, shoulders and side slopes on lake plains, and on risers and treads on terraces of streams and outwash plains. Slope ranges from 0 to 25 percent. Mean annual precipitation ranges from 29 to 43 inches, and mean annual temperature ranges from 47 to 52 degrees F. The frost free period is 133 to 198 days, and elevation ranges from 720 to 1,100 feet above msl.
GEOGRAPHICALLY ASSOCIATED SOILS: The Glenford series is a member of the drainage sequence that includes the well drained Mentor, somewhat poorly drained Fitchville, poorly drained Sebring, and very poorly drained Luray soils. Chagrin, Lobdell, and Orrville soils are on adjacent flood plains and have lower silt content. Caneadea and Canadice soils are on adjacent lacustrine areas and have higher clay content. Wheeling, Chili, Bogart, and Jimtown soils are on nearby gravelly outwash. Nearby upland soils derived from till include Wooster, Rittman, Ellsworth, and Pierpont soils and members of their drainage sequences.
DRAINAGE AND PERMEABILITY: Moderately well drained. The potential for surface runoff ranges from low to very high. Permeability is moderate or moderately slow in the upper part of the subsoil and moderately slow in the lower part of the subsoil and the substratum. Depth to the top of an intermittent apparent seasonal high water table is from 1.0 to 2.0 feet from December to April in normal years.
USE AND VEGETATION: Most areas have been cleared and used for cropland or permanent pasture. Corn, small grains, and hay are the principal crops. Some areas are still in woodland. Many areas near cities are in nonagricultural uses. Native vegetation was deciduous forest.
DISTRIBUTION AND EXTENT: Northeastern, eastern and southern Ohio, southwestern Pennsylvania and northwestern West Virginia. MLRA's 99, 100, 111, 114, 121, 124, 126, 139 and 140. The series is of large extent with a total of about 129,000 acres.
MLRA OFFICE RESPONSIBLE: Amherst, Massachusetts.
SERIES ESTABLISHED: Licking County, Ohio, 1930.
REMARKS: This revision reflects taxonomic classification updates of the 8th Edition of Keys to Soil Taxonomy. It is anticipated that the Glenford soils correlated in MLRA's other than those in Region R may be recorrelated as new series in future MLRA update activities.
