QUENCHEROO SERIES


The Quencheroo series consist of deep well drained soils that formed in alluvium. Quencheroo soils occur on stream terraces and have slopes of 0 to 2 percent. Permeability is moderately slow. The average annual precipitation is about 10 inches and the average annual air temperature is about 49 degrees F.

TAXONOMIC CLASS: Fine-loamy, mixed, superactive, mesic Aridic Haploxerolls

TYPICAL PEDON: Quencheroo silt loam--on a south facing slope of 1 percent in irrigated cropland. When described on September 29, 1987, the soil was dry to 5 inches and slightly moist below that depth. (Colors are for dry soils only unless otherwise noted.)

Ap--0 to 5 inches; grayish brown (10YR 5/2) silt loam, very dark grayish brown (10YR 3/2) moist; moderate fine and medium subangular blocky structure; slightly hard, friable, sticky and plastic; many fine and very fine and few medium roots; common fine and very fine and few medium and coarse vesicular and tubular pores; neutral (pH 6.8); clear smooth boundary. (4 to 11 inches thick)

Bw1--5 to 11 inches; brown (10YR 5/3) loam, dark brown (10YR 3/3) moist; moderate fine and medium subangular blocky structure; slightly hard, friable, sticky and plastic; common fine and very fine roots; few fine, very fine and medium tubular pores; neutral (pH 6.6); abrupt smooth boundary. (3 to 8 inches thick)

Bw2--11 to 21 inches; brown (10YR 5/3) loam, dark grayish brown (10YR 4/2) moist; moderate fine and medium subangular blocky structure; hard, firm, sticky and plastic; few fine and very fine roots; many fine and very fine and few medium tubular pores; neutral (pH 6.6); clear smooth boundary. (6 to 14 inches thick)

C1--21 to 30 inches; brown (10YR 5/3) silt loam, dark brown (10YR 4/3) moist; few fine distinct mottles; weak fine and medium subangular blocky structure; 30 percent weakly cemented cicada nodules; slightly hard, friable, slightly sticky and slightly plastic; few fine and very fine roots; many fine and very fine and few medium tubular pores; neutral (pH 6.9); gradual smooth boundary. (6 to 14 inches thick)

C2--30 to 49 inches; brown (10YR 4/3) silt loam, dark brown (10YR 3/3) moist; few fine and medium distinct mottles; weak fine and medium subangular blocky structure; slightly hard, friable, sticky and plastic; trace of roots; few fine and very fine tubular pores; neutral (pH 6.9); abrupt smooth boundary. (7 to 20 inches thick)

R--49 inches; lime and silica cap on basalt bedrock.

COMPETING SERIES: These are the Agency, Capona, Lovline, and Sutro series. Agency and Lovline soils are 20 to 40 inches to bedrock. Capona soils are 20 to 40 inches deep to bedrock and contains 5 to 35 percent rock fragments in the control section. Sutro soils are 20 to 40 inches deep to a paralithic contact and contain 15 to 35 percent rock fragments in the control section.

GEOGRAPHIC SETTING: Quencheroo soils are on stream terraces. These soils formed in alluvium. Slopes are 0 to 2 percent. Elevation is 3500 to 4200 feet. The average annual precipitation is 9 to 11 inches. The average annual air temperature is 48 to 51 degrees F, and the frost free period is 100 to 120 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bruncan, Harsan, Idow, Loupence, Schnipper, and Snowmore soils. Idow, Schnipper, and Snowmore soils have a duripan above 40 inches. Bruncan soils have a duripan above 20 inches and have bedrock above 40 inches. Harsan soils have argillic horizons overlying a calcic horizon. Loupence soils have a fine silty control section, are very deep, and have an irregular decrease in organic carbon. Bruncan, Harsan, Idow, Snowmore, and Schnipper soils have ochric epipedons. Bruncan, Harsan, Idow, Snowmore, and Schnipper soils occur on basalt plains. Loupence soils occur on the same landscape as the Quencheroo soil.

DRAINAGE AND PERMEABILITY: Well drained; runoff is very slow; permeability is moderately slow.

USE AND VEGETATION: Quencheroo soils are used for irrigated cropland pastureland and hayland.

DISTRIBUTION AND EXTENT: Quencheroo soils are of small extent in south western Idaho.
