STANEY SERIES

The Staney series consists of very deep, very poorly drained organic soils that formed in partially decomposed sedges. Staney soils are on nearly level marsh areas along rivers and streams. Slopes range from 0 to 5 percent. Mean annual precipitation is about 100 inches and mean annual temperature is about 55 degrees F.

TAXONOMIC CLASS: Euic Fluvaquentic Cryofibrists

TYPICAL PEDON: Staney peat - sedges. (All colors are for moist soil)

Oi--0 to 2 inches; mat of living mosses and sedges; many fine roots; abrupt wavy boundary. (0 to 3 inches thick)

Oe--2 to 4 inches; black (5YR 2.5/1, broken face and pressed) sedge peat (60 percent fibers unrubbed, 40 percent rubbed); liquid removed by squeezing is turbid; nonsticky and slightly plastic; very strongly acid (pH 4.5); clear wavy boundary. (0 to 5 inches thick)

0'i1--4 to 23 inches; reddish brown (5YR 4/4, broken face and pressed) sedge peat (90 percent fibers unrubbed, 75 percent rubbed); color values are slightly higher when squeezed than in wet condition; liquid removed by squeezing is turbid; nonsticky and slightly plastic; extremely acid (pH 4.2); clear wavy boundary. (15 to 25 inches thick)

O'i2--23 to 43 inches; dark reddish brown (5YR 3/2, broken face or pressed) peat (90 percent fibers unrubbed, 75 percent rubbed); liquid removed by squeezing is turbid; nonsticky and slightly plastic; very strongly acid (pH 4.5); abrupt smooth boundary. (15 to 25 inches thick)

Cg--43 to 47 inches; black (5YR 2.5/1) fine gravel and sand; about 5 percent admixture of mucky peat; single grain; loose; nonsticky and nonplastic; extremely acid (pH 4.0); abrupt wavy boundary. (2 to 5 inches thick)

O'e--47 to 63 inches; black (5YR 2.5/1, broken face and pressed) mucky peat (50 percent fibers unrubbed, 40 percent rubbed); liquid removed by squeezing is turbid; nonsticky, slightly plastic; extremely acid (pH 4.0).

TYPE LOCATION: Hollis Area, Alaska; about 20 yards south of No. 1100 Road, 8.5 miles from Thorne Bay; SE 1/4 NE 1/4 sec. 8, T. 71 S., R. 84 E., Copper River Meridian.

RANGE IN CHARACTERISTICS: The mean annual soil temperature ranges from 38 to 42 degrees F. The soil is never frozen in most years below 2 inches due to maritime influence. Within the control section, layers of fine gravel, sand and silt of non-volcanic origin range in thickness from 2 to 5 inches. Hue of the organic material is 5YR or 7.5YR, value moist ranges from 2 through 4 and chroma moist from 1 through 4. Chroma tends to be 1 or near neutral at a depth of 4 feet and below. The reaction throughout the profile is extremely or very strongly acid. pH ranges from 4.0 to 5.0 (0.01M CaCl2)), with some organic horizon in each profile having a pH of 4.5 or higher.

COMPETING SERIES: This is the Saltery series which has a pH of less than 4.5 throughout the organic materials.

GEOGRAPHIC SETTING: Staney soils occur in marshes along rivers and streams that have, in most places, a water table just below or above the surface throughout the year. The climate is cool and humid with average annual rainfall greater than 100 inches. The average annual temperature ranges from 53 to 57 degrees F. Slopes are 0 to 5 percent. Elevation ranges from 100 to 300 feet.

GEOGRAPHICALLY ASSOCIATED SOILS: These include the Karta, Kina, Kogish, Kupreanof, Tonowek, Tuxekan, Tolstoi, Ulloa, and Wadleigh soils. Karta, Kupreanof, Tolstoi and Ulloa soils are well drained mineral soils of uplands. Kina soils are dominantly hemic material. Kogish soils are dominantly sphagnum. Tonowek and Tuxekan soils are well drained mineral soils with gravelly substrata on alluvial plains. Wadleigh soils are somewhat poorly drained mineral soils on footslopes.

DRAINAGE AND PERMEABILITY: Very poorly drained. Permeability is rapid. Runoff is ponded to slow.

USE AND VEGETATION: The Staney soils are used for wildlife habitat, watershed protection, and recreation. The vegetation is dominated by sedges. Stunted conifers are present in places.

DISTRIBUTION AND EXTENT: Southeast Alaska. The series is of moderate extent.

SOIL SURVEY REGIONAL OFFICE (SSRO) RESPONSIBLE: WASILLA, ALASKA

SERIES ESTABLISHED: Hollis Area, Alaska, 1969.

REMARKS: Diagnostic horizons and features recognized in this profile include: organic material from 0 to 43 and 47 to 63 inches; a mineral layer from 43 to 47 inches; a pH of 4.5 (0.01M CaCl2) from 23 to 43 inches; it is assumed that the soil never freezes below a depth of 2 inches in most years due to maritime influence.

The Staney series formerly classified as dysic. However, at least one layer in each profile has a pH of 4.5 (0.01M CaCl2) or greater.
