CORINNA SERIES
The Corinna series consists of shallow, somewhat excessively drained soils that formed in a loamy mantle of glacial till overlying limestone-interbedded phyllite, calcareous metasiltstone, or pelitic limestone bedrock. The Corinna soils are on slightly convex summits and shoulders of ground moraines. Estimated saturated hydraulic conductivity is moderately high. Slopes range from 3 to 15 percent. The mean annual temperature is about 6 degrees C, and the mean annual precipitation is about 1090 mm.
TAXONOMIC CLASS: Loamy, isotic, frigid Lithic Dystrudepts
TYPICAL PEDON: Corinna channery loam on a 6 percent northeast-facing slope in a cultivated field of potatoes. (Colors are for moist soil unless otherwise indicated. When described on June 9, 2003 the soil was moist throughout.)
Ap--0 to 22 cm; brown (10YR 4/3) channery loam; pale brown (10YR 6/3) dry; moderate, fine and medium granular structure; very friable; slightly sticky and slightly plastic; common very fine and fine roots throughout; 15 percent subangular channers and 5 percent subrounded gravel; slightly acid (pH 6.2); abrupt wavy boundary. (18 to 25 cm thick)
Bw--22 to 33 cm; 65 percent yellowish brown (10YR 5/6) and 35 percent strong brown (7.5YR 5/6) parachannery loam; moderate fine and medium subangular blocky structure; very friable; slightly sticky and slightly plastic; few very fine and fine roots throughout; 20 percent subangular parachanners, 5 percent angular channers, and 5 percent subrounded gravel; moderately acid (pH 5.7); abrupt wavy boundary. (8 to 23 cm thick)
R--33 cm; fractured limestone-interbedded phyllite bedrock
TYPE LOCATION: Penobscot County, Maine; Town of Corinth, in a cultivated field 2100 feet east and 700 feet south of the intersection of Maine Hwy. 11/43 and Notch Road; USGS West Corinth, ME topographic quadrangle; lat. 44 degrees 59 minutes 38 seconds N. and long. 69 degrees 2 minutes and 36 seconds W., NAD 27.
RANGE IN CHARACTERISTICS: The mineral solum thickness and depth to bedrock range from 25 to 50 cm. Rock fragments in the form of channers and gravel range from 5 to 35 percent in the solum. Pararock fragments range from 0 to 35 percent in the solum. Reaction in unlimed areas is very strongly acid to slightly acid in the surface and strongly acid to neutral in the subsoil. Average clay content in the particle-size control section is 8 to 15 percent.
Forested areas may have an Oe horizon with hue of 10YR or 7.5YR, value of 2 to 3, and chroma of 1 or 2.
The Ap, or A horizon where present, has moist hue of 10YR, value of 3 or 4, and chroma of 2 to 4. Dry colors are hue of 10YR, value of 5 or 6, and chroma of 2 to 4. Texture is loam or silt loam in the fine-earth fraction.
The Bw horizon has hue of 7.5YR to 2.5Y, value of 3 to 5, and chroma of 4 or 6. Texture is loam or silt loam in the fine-earth fraction.
Some pedons have 2Cr horizons with variegated colors in a wide spectrum of hues, values, and chroma. It is extremely weakly to moderately cemented. It constitutes paralithic materials.
COMPETING SERIES: This is the
Insula series. Insula soils originate outside Region R and have mean annual precipitation of 711 mm. They formed in non-calcareous till and typically have granitic rock fragments.
GEOGRAPHIC SETTING: Corinna soils are on slightly convex summits and shoulders of ground moraines. Slope ranges from 3 to 15 percent. The soils formed in glacial till derived from limestone-interbedded phyllite, calcareous metasiltstone, and pelitic limestone. Surface stones and boulders range from 0 to 3 percent. Elevations range from 50 to 230 meters. The mean annual precipitation ranges from 1000 to 1135 mm. Mean annual temperature ranges from 5 to 7 degrees C. The frost-free period is 115 to 155 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Boothbay,
Chesuncook,
Kenduskeag,
Penobscot,
Pushaw,
Sebasticook,
Swanville,
Telos, and
Wassookeag soils. The moderately well drained Boothbay, the somewhat poorly drained Pushaw, and the poorly drained Swanville soils formed in very deep glaciomarine or glaciolacustrine sediments. They are on adjacent lake plains or marine terraces at slightly lower elevations. The very deep moderately well drained Chesuncook soils, and the very deep somewhat poorly drained Telos soils formed in lodgment till, and are on side slopes and toe slopes. The moderately deep well drained Penobscot soils are on linear to slightly convex summits and side slopes. The deep well drained Sebasticook soils are on linear to slightly convex side slopes. The moderately deep moderately well drained Wassookeag soils are on linear to slightly concave summits and side slopes. The very deep, somewhat poorly drained Kenduskeag soils are on footslopes.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat excessively drained. Estimated saturated hydraulic conductivity is moderately high.
USE AND VEGETATION: These soils are used primarily for row crops, hay production, and pasture. Cultivated crops are potatoes, winter rye, barley, and corn. Some areas are forested. northern white cedar (Thuja occidentalis), sugar maple (Acer saccharum), white ash (Fraxinus americana), basswood (Tilia Americana) and American beech (Fagus grandifolia).
DISTRIBUTION AND EXTENT: Ground moraines in central Maine, limited mainly to the northwest part of Southern Penobscot County, Maine, MLRA 144B. The series is of small extent totaling about 6500 acres.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Amherst, Massachusetts
SERIES ESTABLISHED: Penobscot County, Maine, 2016
REMARKS: The series is named for the village of Corinna, in southwestern Penobscot County. It is part of a proposed suite of soils that includes Sebasticook, Penobscot, and Wassookeag. They developed in till that is shallow to very deep to calcareous metasedimentary bedrock of the Waterville and Sangerville Formations in central Maine, MLRA 144B. In comparison to other soils of the region they have a higher base saturation, water-holding capacity, and saturated hydraulic conductivity. They are considered agriculturally productive, particularly for potatoes and small grains and corn.
Diagnostic horizons and features recognized in this pedon include:
1. Ochric epipedon -- the zone from the soil surface to a depth of 22 cm (Ap horizon).
2. Cambic horizon -- the zone from a depth of 22 to 33 cm (Bw horizon).
3. Lithic contact -- at a depth of 33 cm (R layer).
ADDITIONAL DATA: Primary characterization samples from pedon 03N0757, samples 03N03765, 03N03768, from Penobscot County, Maine, samples by NSSL, Lincoln, NE, 08/04.
