TYPE LOCATION: Manistee County, Michigan; about 3 miles south west of the village of Copmish; 400 feet north and 900 feet east of the southwest corner of section 25, T. 24 N., R. 14 W., Springdale township; USGS Copmish 7.5 minute topographic quadrangle); lat. 44 degrees 26 minutes 30 seconds N. and long. 85 degrees 57 minutes 23 seconds W. NAD83.
RANGE IN CHARACTERISTICS: The depth to the base of soil development ranges from 20 to 50 inches. The depth to the ortstein is 10 to 20 inches. This soil is saturated for 90 to 120 days when soil temperature exceeds 5 degrees C. The soil contains 0 to 5 percent fine gravel throughout. Reaction of the solum ranges from extremely acid to strongly acid.
Some pedons have an Oa horizon of well decomposed forest litter from 1 to 4 inches thick.
The A horizons has hue of 10YR to 5YR or is neutral, value of 2 to 4 and chroma of 0 to 2. Cultivated areas have an Ap horizon that has hue of 10YR, value of 2 to 4 and chroma of 1 or 2. The A horizons are mucky sand, mucky fine sand, sand or fine sand.
The E horizon has hue of 10YR or 7.5YR, value of 4 to 7 and chroma of 1 to 3. The E horizon is sand or fine sand.
The Bhsm horizon has hue of 2.5YR to 7.5YR, and value and chroma of 1 to 3. Cementation ranges from weak to strong. More than 90 percent of the horizon is cemented. The texture is sand or fine sand. Some pedons have a Bsm horizon, up to 3 inches thick with value and/or chroma of 4.
Some pedons have a Bs horizon with hue of 2.5YR to 10YR, value of 3 to 6, and chroma of 4 to 6. Ortstein ranges from 0 to 70 percent in this horizon. The texture is sand or fine sand.
Some pedons have BC horizons with hue of 2.5YR to 10YR, value of 3 to 6 and chroma of 4 to 6. It is sand or fine sand. .
The C horizon has hue of 7.5YR or 10YR, value of 4 to 7, and chroma of 2 to 6. It is sand or fine sand. Reaction is strongly acid to slightly acid.
COMPETING SERIES: This is the Saugatuck series in the same family. Saugatuck soils are somewhat poorly drained and saturated for 75 to 90 days when the soil temperature is above 5 degrees C.
GEOGRAPHIC SETTING: Jebavy soils are on lake plains and outwash plains. Slope is 0 to 2 percent. The soils formed in glaciofluvial deposits. The mean annual temperature is 47 to 49 degrees F, the mean annual precipitation ranges from 30 to 38 inches and the elevation ranges from 600 to 800 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: The somewhat poorly drained Pipestone and Saugatuck soils, the poorly drained Kingsville soils, and the moderately well drained Covert soils. The Pipestone, Kingsville and Covert soils do not have ortstein that is at least weakly cemented when moist that is in more than half of each pedon.
DRAINAGE AND PERMEABILITY: Poorly drained. The soil has an apparent seasonal high water table that ranges from 1.0 foot above the surface to 1.0 foot below for more then 120 days and from 90 to 120 days when soil temperature exceeds 5 degrees C at some time from October to June. Runoff is negligible. Permeability is moderate in the ortstein and rapid in the rest of the profile.
USE AND VEGETATION: Most areas are in forest. A small acreage is under cultivation to blueberries. Principal tree species include red maple, quaking aspen, eastern white pine, jack pine and eastern hemlock.
DISTRIBUTION AND EXTENT: West central Lower Peninsula of Michigan and central New York. The series is of minor extent.
MLRA OFFICE RESPONSIBLE: Indianapolis, Indiana
SERIES ESTABLISHED: Newaygo County, Michigan, 1990. Soils previously correlated as Saugatuck in Newaygo Country were changed to the name Jebavy in the second amendment, dated May 21, 1991, to the Classification and Correlation of Newaygo County, Michigan. The series was proposed in Mason County, Michigan in 1991. The source of the name is a road in Mason County.
The pedon was moved from Mason County to its present location to better represent the shallow classification.
REMARKS: Diagnostic horizons and features recognized in this pedon are: ochric epipedon - the zone from the surface to 17 inches (A and E
horizons);
albic horizon - the zone from 4 to 17 inches (E1 and E2 horizons);
spodic horizon - the zone from 17 to 31 inches (Bhsm, and Bs horizons); aquic soil moisture regime.
Shallow classification reflects the 10 to 20 inches to the ortstein layer. The particle-size control section is the zone from 10 to 17 inches.
