MEADVIEW SERIES

The Meadview series consists of very deep, well drained soils that formed in alluvium from granite and limestone. Meadview soils are on fan remnants. Slopes range from 1 to 40 percent. The mean annual precipitation is about 10 inches and the mean annual air temperature is about 63 degrees F.

TAXONOMIC CLASS: Sandy-skeletal, mixed, thermic Durinodic Haplocalcids

TYPICAL PEDON: Meadview very cobbly sandy loam - rangeland. (Colors are for dry soil unless otherwise noted.)

A--0 to 2 inches; brown (10YR 5/3) very cobbly sandy loam, brown (10YR 4/3) moist; moderate thin platy structure; soft, very friable, nonsticky and nonplastic; many very fine roots; many fine tubular pores; 30 percent gravel, 20 percent cobble, 5 percent stone; strongly effervescent, 11 percent calcium carbonate equivalent; moderately alkaline (pH 8.0); abrupt smooth boundary. (1 to 6 inches thick)

Bk1--2 to 10 inches; brown (10YR 5/3) very cobbly sandy loam, brown (10YR 4/3) moist; weak fine subangular blocky structure; slightly hard, very friable, slightly sticky and nonplastic; many fine roots; few very fine and fine tubular pores; 30 percent gravel, 20 percent cobble, 5 percent stone; common decomposed fragments of granite; strongly effervescent, 16 percent calcium carbonate equivalent, 1/8 to 1/2 inch thick calcium carbonate pendants on the underside of rock fragments; moderately alkaline (pH 8.0); clear wavy boundary.

Bk2--10 to 21 inches; brown (10YR 5/3) very cobbly sandy loam, brown (10YR 4/3) moist; weak fine subangular blocky structure; slightly hard, very friable, slightly sticky and nonplastic; many fine roots; few very fine and fine tubular pores; 30 percent gravel, 20 percent cobble, 5 percent stone; common decomposed fragments of granite; violently effervescent, few fine soft calcium carbonate masses, 19 percent calcium carbonate equivalent, 1/8 to 1/2 inch thick calcium carbonate pendants on the underside of rock fragments; moderately alkaline (pH 8.0); abrupt smooth boundary. (Combined thickness of the Bk horizons is 14 to 29 inches.)

Bkq1--21 to 31 inches; brown (10YR 5/3) extremely gravelly coarse sand, brown (10YR 4/3) moist; massive; slightly hard to hard, firm to very firm, nonsticky and nonplastic; few very fine roots; many very fine irregular pores; 50 percent gravel, 20 percent cobble; brittle discontinuous lenses of silica and calcium carbonate cemented material; slightly effervescent, few areas in matrix are violently effervescent, 1/8 to 1/2 inch calcium carbonate pendants on the underside of rock fragments; moderately alkaline (pH 8.0); abrupt wavy boundary.

Bkq2--31 to 42 inches; brown (10YR 5/3) extremely gravelly coarse sand, brown (10YR 4/3) moist; massive; very hard, firm and brittle, nonsticky and nonplastic; 50 percent gravel, 20 percent cobble; slightly effervescent; moderately alkaline (pH 8.0); abrupt wavy boundary.

Bkq3--42 to 52 inches; brown (10YR 5/3) extremely gravelly coarse sand, brown (10YR 4/3) moist; massive; extremely hard and very hard, very firm, nonsticky and nonplastic; few very fine roots; many very fine irregular pores; 50 percent gravel, 20 percent cobble; slightly effervescent; moderately alkaline (pH 8.0); abrupt wavy boundary. (Combine thickness of the Bkq horizons is 20 to 40 inches.)

C--52 to 60 inches; pale brown (10YR 6/3) stratified extremely gravelly coarse sand, brown (10YR 5/3) moist; slightly hard, very friable, nonsticky and nonplastic; few very fine roots; many very fine irregular pores; 50 percent gravel, 20 percent cobble; slightly effervescent; moderately alkaline (pH 8.0).

TYPE LOCATION: Mohave County, Arizona; about 5 miles southeast of Meadview; 1,500 feet west and 2,000 west of the northeast corner of section 7, T. 29 N, R. 16 W. Gila and Salt River Base Meridian.

RANGE IN CHARACTERISTICS:

Soil moisture - Intermittently moist in some part of the moisture control section during December - February and for less than 20 days cumulative during July - September. Driest during May and June. Typic aridic soil moisture regime.

Soil temperature: 59 to 72 degrees F.

Rock fragments: 35 to 75 percent.

Clay content: 5 to 18 percent in the Bk. Averages less than 10 percent in the control section

Depth to calcic horizon: 2 to 18 inches

Depth to gravel and sand: 20 to 30 inches

Depth to durinodic horizon: 14 to 30 inches

Reaction: Slightly alkaline or moderately alkaline

A horizon - Hue: 10YR or 7.5YR

Value: 5 to 7 dry, 4 and 5 moist

Chroma: 3 to 6, dry and moist

Bk horizon - Hue: 10YR and 7.5YR

Value: 5 through 8 dry, 4 through 6 moist

Chroma: 3 through 6, dry and moist.

Calcium carbonate equivalence in the fine earth fraction: 10 to 30 percent.

Bkq horizons - Hue: 10YR and 7.5YR

Value: 5 through 8 dry and 4 through 6 moist.

Chroma: 3 through 6 dry or moist.

Calcium carbonate equivalent in the fine earth fraction: 5 to 15 percent.

Other features: Subhorizons have discontinuous lenses of silica and calcium carbonate cementation or suspended pan fragments with a laminar cap. Some pedons have up to 30 percent calcium carbonate and silica masses.

C horizon (when present) - Value: 5 or 6 dry, 4 or 5 moist

COMPETING SERIES: There are no competing series at this time.

GEOGRAPHIC SETTING: Meadview soils are on fan remnants. Elevations range from 1,600 to 4,500 feet. Slopes range from 1 to 40 percent. These soils formed in alluvium mainly from granite and limestone. The mean annual precipitation is 5 to 12 inches. The mean annual air temperature is 57 to 70 degrees F. The frost-free period is 180 to 280 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Arizo, Greyeagle, Detrital, Skelon and Yurm soils. Arizo soils lack a calcic horizon. Greyeagle and Yurm soils are shallow to a hardpan. Detrital soils are loamy. Skelon soils are moderately deep to a hardpan.

DRAINAGE AND PERMEABILITY: Well drained; very low to high runoff; moderately rapid permeability.

USE AND VEGETATION: These soils are used for rangeland and wildlife habitat. Vegetation includes blackbrush, Joshua tree and Mohave Yucca.

DISTRIBUTION AND EXTENT: Mojave Desert of Northwestern Arizona and southern Nevada. Meadview soils are of moderate extent. MLRA is 30.
