BODECKER SERIES

The Bodecker series consists of very deep, excessively drained soils that formed in fan or stream alluvium. These soils are on alluvial fans and floodplains and have slopes of 0 to 8 percent. The mean annual precipitation is about 14 inches and the mean annual air temperature is about 61 degrees F.

TAXONOMIC CLASS: Sandy-skeletal, mixed, thermic Ustic Torrifluvents

TYPICAL PEDON: Bodecker extremely gravelly sandy loam - cropland. (Colors are for dry soil unless otherwise noted.)

Apl--0 to 1 inch; brown (7.5YR 5/3) extremely gravelly sandy loam, brown (7.5YR 4/3) moist; weak thin platy structure; soft, very friable, nonsticky and nonplastic; many fine roots; many fine irregular pores; 65 percent gravel; slightly effervescent; moderately alkaline (pH 8.0); abrupt wavy boundary. (1 to 2 inches thick)

Ap2--1 to 14 inches; brown (7.5YR 5/4) very gravelly sandy loam, brown (7.5YR 4/4) moist; massive; soft, very friable, nonsticky and nonplastic; many very fine roots; many fine irregular pores; 55 percent gravel; slightly effervescent; moderately alkaline (pH 8.0); clear wavy boundary. (5 to 13 inches thick)

C1--14 to 52 inches; pale brown (10YR 6/3) extremely gravelly sand, brown (10YR 5/3) moist; single grain; loose, nonsticky and nonplastic; common very fine roots; many fine irregular pores; 75 percent gravel; slightly effervescent; moderately alkaline (pH 8.0); abrupt wavy boundary.

C2--52 to 60 inches; light brownish gray (10YR 6/2) silt loam, grayish brown (10YR 5/2) moist; massive; slightly hard, very friable, slightly sticky and slightly plastic; few very fine roots; many very fine tubular pores; slightly effervescent; slightly alkaline (pH 7.5). (Combined thickness of the C horizons is 45 to 56 inches)

TYPE LOCATION: Cochise County, Arizona; about 2 miles east of Elfrida; 1900 feet east, 1700 feet south of the northwest corner of section 14, T. 20 S., R. 26 E. Lat. 31 degrees 41 minutes 43 seconds N. and long. 109 degrees 39 minutes 50 seconds W., NAD83

RANGE IN CHARACTERISTICS:

Soil moisture - Intermittently moist in some part of the moisture control section during July-September and December-February. Driest during May and June. Ustic aridic soil moisture regime.

Soil temperature: 59 to 69 degrees F.

Rock fragments: 35 to 85 percent in the particle-size control section

Reaction: neutral to strongly alkaline

Calcium carbonate equivalent: less than 5 percent, decreases with depth

A and C horizons
Hue: l0YR, 7.5YR
Value: 4 to 6 dry, 3 to 6 moist
Chroma: 2 to 4, dry or moist
Texture: sandy loam, loamy sand, sand, loamy fine sand, coarse sand, loamy coarse sand, coarse sandy loam, very fine sandy loam, silt loam, fine sandy loam, sandy clay loam

COMPETING SERIES: This is the Chipotle (NM) series. Chipotle soils have redder hue (5YR) and are slightly acid.

GEOGRAPHIC SETTING: Bodecker soils are on flood plains and alluvial fans. They formed in fan or stream alluvium from volcanic, granitic and limestone rock. Slopes range from 0 to 8 percent. Elevations range from 2,900 to 5,200. The mean annual precipitation is 12 to 16 inches and the mean annual air temperature is 57 to 67 degrees F. The frost-free period is 170 to 250 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Comoro, Forrest, and Ubik soils. Forrest soils are fine textured. Comoro and Ubik soils are coarse-loamy.

DRAINAGE AND PERMEABILITY: Excessively drained; slow runoff; very rapid permeability. Bodecker soils are subject to flooding.

USE AND VEGETATION: Bodecker soils are used for livestock grazing, wildlife habitat and irrigated cropland. Crops grown include corn, cotton, barley, and other small grain. Vegetation is winterfat, big sacaton, and plains bristlegrass.

DISTRIBUTION AND EXTENT: Southern Arizona and West Texas. Bodecker soils are not extensive. This soil occurs in MLRAs 38, 40, 41, and 42.
