TYPE LOCATION: Jackson County, Michigan; about 3 1/2 miles southwest of Munith; 1,800 feet south and 750 feet east of the northwest corner of sec. 26, T. 1 S., R. 1 E.; U.S.G.S. Gilletts Lake topographic quadrangle; lat. 42 degrees 21 minutes 34.2 seconds N. and long. 84 degrees 17 minutes 17.3 seconds W., NAD 27; UTM Zone 16, 723332 easting and 4693258 northing, NAD 83.
RANGE IN CHARACTERISTICS: The thickness of the solum ranges from 20 to 50 inches. The 10- to 40-inch particle-size control section averages 5 to 18 percent clay and 35 to 55 percent fine sand or coarser.
The Oap horizon has hue of 5YR to 10YR, or is neutral, value of 2, 2.5, or 3, and chroma of 0 to 3. It has weak or moderate granular or subangular blocky structure. Some pedons are massive. In some pedons the muck contains up to 60 percent by volume of mineral material. Fiber content is less than 15 percent when rubbed. Reaction ranges from moderately acid to slightly alkaline.
The Bg horizon has hue of 10YR to 5Y, value of 4 to 6, and chroma of 1 or 2. It is dominantly silt loam, fine sandy loam, or sandy loam with strata of sandy clay loam, loam, loamy fine sand, loamy sand, fine sand, or sand. It has weak or moderate subangular blocky structure. Rock fragment content ranges from 0 to 14 percent. Reaction ranges from moderately acid to slightly alkaline.
The Cg horizon has hue of 10YR to 5Y, value of 4 to 6, and chroma of 1 or 2. It is stratified silt loam, loam, sandy loam, fine sandy loam, loamy fine sand, loamy sand, or sand. Rock fragment content ranges from 0 to 14 percent. It contains carbonates in most pedons.
COMPETING SERIES: There are no other series in this family. The Biddeford, Clatsop, Haug, Kjar, Linwood, Martisco, Menlo, Pavilion, Palms, Philbon, Shalcar, Thomas, and Twig series are in related families. Biddeford, Clatsop, and Thomas soils contain more than 18 percent clay in the particle-size control section. Haug and Twig soils have a frigid temperature regime. Kjar and Martisco soils are carbonatic. Linwood, Palms Philbon, and Shalcar soils have organic layers that are thicker than 16 inches. Menlo and Pavilion soils are in a similar family but have an active cation-exchange activity class. Menlo soils have a densic contact with till within the series control section and are in LRR R. Pavilion series do not have a cambic horizon and are in LRRs L and R.
GEOGRAPHIC SETTING: Henrietta soils formed in organic materials less than 16 inches thick and the underlying loamy and sandy sediments. They are on glacial drainageways, lake plains, outwash plains, and till plains. Slope gradients range from 0 to 2 percent. Mean annual temperature ranges from 45 to 55 degrees F., mean annual precipitation ranges from 27 to 42 inches, frost-free period ranges from 130 to 198 days, and elevation ranges from 570 to 1,530 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: Henrietta soils are associated with the Dixboro, Edwards, Gilford, Houghton, Lamson, and Palms soils. Dixboro, Gilford, and Lamson soils are on higher elevations and lack the histic epipedon that is present in the Henrietta soils. Edwards, Houghton, and Palms soils are on the same landform position and have thicker histic layers than the Henrietta soils.
DRAINAGE AND PERMEABILITY: Very poorly drained. The potential for surface runoff is negligible. Permeability is moderate.
USE AND VEGETATION: Most areas of these soils are used for cropland. Some small areas are used for pasture and woodland.
DISTRIBUTION AND EXTENT: Primarily in MLRAs 97, 98, 99, 100, 101, and 111 in southern part of lower Michigan, northern Indiana, and possibly northern Ohio. The soils are of small extent.
MLRA OFFICE RESPONSIBLE: Indianapolis, Indiana.
SERIES ESTABLISHED: Jackson County, Michigan, 1979.
REMARKS: Diagnostic horizons and features recognized in this pedon are: histic epipedon - from the surface to 12 inches (Oap); cambic horizon - from 18 to 43 inches (Bg2 and Bg3); redoximorphic features in all horizons between the surface and 60 inches. Aquic moisture regime.
