ROSEBERRY SERIES


The Roseberry series consists of very deep, poorly drained soils that formed in material from coarse textured glacial outwash. Roseberry soils are on outwash plains and have slopes of 0 to 3 percent. The average annual precipitation is about 23 inches and the average annual air temperature is about 40 degrees F.

TAXONOMIC CLASS: Sandy, mixed Humic Cryaquepts

TYPICAL PEDON: Roseberry coarse sandy loam, pasture. (Colors are for dry soil unless otherwise noted.)

A1--0 to 7 inches; dark gray (10YR 4/1) coarse sandy loam, very dark gray (2.5Y 3/1) moist; few fine faint very dark brown (7.5YR 2/2) moist, mottles; moderate fine and very fine granular structure; slightly hard, friable, slightly sticky and slightly plastic; many fine roots; medium acid (pH 5.7); gradual smooth boundary. (5 to 9 inches thick)

A2--7 to 13 inches; gray (10YR 5/1) coarse sandy loam, very dark gray (2.5Y 3/1) moist; few fine faint very dark brown (7.5YR 2/2) moist, mottles; weak medium subangular blocky structure; slightly hard, friable, slightly sticky and slightly plastic; many fine roots; common very fine pores; medium acid (pH 5.5); clear irregular boundary. (4 to 14 inches thick)

C1--13 to 20 inches; light brownish gray (10YR 6/2) loamy coarse sand, dark brown (10YR 3/3) and dark grayish brown (10YR 4/2) moist; common medium faint dark gray and dark olive mottles; weak medium subangular blocky structure parting to moderate fine granular; friable, slightly sticky and slightly plastic; common fine roots; many very fine pores; medium acid (pH 5.6); gradual wavy boundary. (5 to 30 inches thick)

C2--20 to 35 inches; pale brown (10YR 6/3) loamy coarse sand, brown (10YR 4/3) and grayish brown (2.5Y 5/2) moist; single grained; very friable, slightly sticky; few fine roots; many very fine pores; medium acid (pH 5.6); clear wavy boundary. (0 to 20 inches thick)

C3--35 to 55 inches; light brownish gray (10YR 6/2) coarse sand, brown (10YR 4/3) moist; single grained; very friable; medium acid (pH 5.6); gradual wavy boundary. (0 to 30 inches thick)

2C--55 to 64 inches; light brownish gray (10YR 6/2) fine sandy loam, brown (7.5YR 4/3) and dark yellowish brown (10YR 4/4) moist; light olive gray (5Y 6/2) mottles, moist; massive; friable, slightly sticky and slightly plastic; medium acid (pH 5.9); abrupt wavy boundary. (0 to 20 inches thick)

TYPE LOCATION: Valley County, Idaho; about 4 miles north and 1 mile east of Donnelly; 700 feet west and 40 feet south of the northeast corner of sec. 26, T. 17 N., R. 3 E.

RANGE IN CHARACTERISTICS:

Average annual soil temperature - 40 to 45 degrees F.
Average summer soil temperature - 53 to 55 degrees F.
Depth to contrasting textures - 40 to 60 inches
Base saturation - 25 to 50 percent

A horizon
Value - 3 through 5 dry, 2 or 3 moist
Chroma - 0 through 2 dry and moist
Reaction - moderately to strongly acid

C horizon
Value - 4 through 6 dry, 3 through 5 moist
Chroma - 2 through 4 dry and moist
Reaction - moderately to strongly acid

COMPETING SERIES: This is the similar Melton series. Melton soils have contrasting textures in the control section.

GEOGRAPHIC SETTING: Roseberry soils are on outwash plains and stream terraces. Slopes are 0 to 3 percent. The soils formed in coarse textured granitic glacial outwash. Elevations are 3,800 to 5,000 feet. Average annual precipitation is 22 to 24 inches. Average January temperature is 20 degrees F.; mean July temperature is 64 degrees F. Average annual temperature is 38 degrees to 43 degrees F. Frost-free season is about 60 to 80 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Archabal and Donnel soils and the competing Melton soils. Archabal and Donnel soils are well drained and lack mottles.

DRAINAGE AND PERMEABILITY: Poorly drained; slow runoff; moderately rapid permeability.

USE AND VEGETATION: Used mainly for pasture, some small grains and clover. Vegetation is mainly grasses, forbs, and shrubs.

DISTRIBUTION AND EXTENT: Distribution is in high mountain valleys; mainly in Valley County, Idaho. The soil is inextensive.
