LOCATION BRINGMEE IDEstablished Series
The Bringmee series consists of very deep, well drained soils that
formed in alluvium from mixed sources. Bringmee soils are on stream
terraces and fan terraces and have slopes of 0 to 8 percent.
Permeability is moderately slow. The average annual precipitation is
about 14 inches, and the average annual air temperature is about 43
degrees F.
TAXONOMIC CLASS: Fine-loamy, mixed, superactive, frigid Pachic Ultic Argixerolls
TYPICAL PEDON: Bringmee loam on a 6 percent south-southwest facing
slope in irrigated pasture at an elevation of 5,000 feet. When
described on October 22, 1979, the soil was moist in the upper 6 inches
and dry below this depth. (Colors are for air dry soils unless
otherwise noted.)

roots; common very fine and fine tubular pores; few thin clay films on
faces of peds; about 10 percent pebbles; slightly acid (pH 6.2); clear

roots; common very fine and fine tubular pores; common thin clay films
on faces of peds; about 14 percent pebbles; slightly acid (pH 6.4);
clear wavy boundary. (7 to 14 inches thick)
Bt3--34 to 47 inches; brown (10YR 5/3) sandy clay loam, dark brown
(10YR 4/3) moist; moderate medium subangular blocky structure; hard
firm, sticky and plastic; few very fine and fine roots; few fine
tubular pores; about 14 percent pebbles; few fine distinct mottles;
neutral (pH 6.6); clear wavy boundary. (10 to 15 inches thick)
2C--47 to 61 inches; light yellowish brown (10YR 6/4) gravelly
sandy loam, yellowish brown (10YR 5/4) moist; few fine distinct
mottles; massive; slightly hard, friable, slightly sticky and slightly
plastic; about 30 percent pebbles; neutral (pH 6.8).
TYPE LOCATION: Blaine County, Idaho, about 3.5 miles north and 4 miles
east of Carey; 2,500 feet west and 600 feet south of the northeast
corner of section 15, T. 1 S., R. 22 E.
RANGE IN CHARACTERISTICS:
Average annual soil temperature - 42 to 47 degrees F.
Thickness of mollic epipedon - 20 to 36 inches
Depth to gravelly and cobbly layer - 40 to 60 inches
Reaction - medium acid to neutral
Base saturation - 50 to 75 percent in the upper 75 cm
Minerology - contains significant amounts of volcanic ash in the upper
part of the control section
Mottles are relect-soil profile - no longer shows any evidence of
wetness
A and BA horizons
Value- 3 or 4 dry and 2 or 3 moist
Chroma- 1 or 2 dry or moist
Bt horizons
Value- 4 through 6 dry, 2 through 4 moist
Chroma- 2 through 4 dry or moist
Textures - L, SCL, or CL
Coarse fragments - range from 5 to 15 percent
Clay control - 20 to 35 percent
Sand percentage upper 10 inches is 15 to 30 fine sand and coarser in
the fine earth
2C horizons
Value of 5 through 7 dry and 4 or 5 moist
Chroma 3 or 4 dry or moist
Textures - GR-SL, GRV-LCOS, or GRV-LS
Coarse fragments - 25 to 60 percent

COMPETING SERIES: These are the Bauscher, Brinegar, DeMasters,
Pinehurst, and Watchabob. Bauscher soils lack volcanic ash in the soil
and have more than 30 percent fine sand and coarser. Brinegar soils
are moderately well drained. DeMasters and Pinehurst soils have "O"
horizons. DeMasters soils are skeletal in the lower part of the
argillic horizon. Pinehurst soils have a 5YR hue and are moderately or
strongly acid in the lower part of the profile. Watchabob soils are
moderately deep to bedrock.
GEOGRAPHIC SETTING: Bringmee soils occur on stream terraces and fan
terraces and have slopes of 0 to 8 percent. Elevation range from 4,800
to 6,000 feet. The soil formed in alluvium derived from mixed sources.
The annual precipitation ranges from 12 to 16 inches, most of which
falls as snow and early spring rain. The annual air temperature ranges
from 40 to 45 degrees F. The frost-free season is 60 to 90 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Carey Lake, Drage,
Hutton, Little Wood, and Molyneux. Carey Lake soils have base
saturation greater than 75 percent in the upper 75 cm and occur on
similar landscapes. Drage soils have loamy-skeletal control sections
and occur on fan terraces. Hutton soils are poorly drained and occur
in drainageways. Little Wood soils have loamy-skeletal control
sections and occur on similar landscape positions. Molyneux soils have
mollic epipedons 10 to 20 inches thick and occur on fan terraces.
DRAINAGE AND PERMEABILITY: Well drained, slow to medium runoff,
moderately slow permeability.
USE AND VEGETATION: Mainly used for irrigated cropland and pasture,
minor extent of rangeland. Vegetation is Basin big sagebrush and Idaho
fescue.
DISTRIBUTION AND EXTENT: Bringmee soils are inextensive in south
central Idaho.
