JUBILEE SERIES

The Jubilee series consists of very deep, poorly drained and very poorly drained soils that formed in alluvium derived from mixed rocks with influence from granitic rocks. Jubilee soils are on swales, flood plains, and sloughs on the toes of alluvial fans. Slopes are 0 to 4 percent. The mean annual precipitation is about 250 mm and the mean annual temperature is about 10 degrees C.

TAXONOMIC CLASS: Coarse-loamy, mixed, superactive, mesic Typic Endoaquolls

TYPICAL PEDON: Jubilee loam--pasture. (Colors are for moist soil unless otherwise noted).

Cg3--114 to 152 cm; olive gray (5Y 4/2) coarse sand, light olive gray (5Y 6/2) dry; single grain; loose, nonsticky and nonplastic; few very fine roots; many very fine and fine interstitial pores; common mica grains; neutral (pH 6.8).

TYPE LOCATION: Douglas County, Nevada; in Carson Valley along the West Fork of the Carson River; about 2,600 feet north and 2,400 feet east of the southwest corner of section 29, T. 12 N., R. 20 E.; USGS Woodfords 7.5 minute topographic quadrangle; latitude 38 degrees 52 minutes 27 seconds N and longitude 119 degrees 45 minutes 41 seconds W; WGS84 Decimal Degrees 38.8740556 latitude, -119.7612778 longitude.

RANGE IN CHARACTERISTICS:
Soil moisture: Usually saturated in some part of the moisture control section during winter and spring, dry in all parts in summer and fall unless irrigated; seasonal periods of aquic moisture regime between December and June during saturation with ground water and anaerobic conditions; an aridic moisture regime exists during the growing season in normal years after ground water levels drop below the moisture control section.
Mean annual soil temperature: 9 to 12 degrees C.
Mollic epipedon thickness: 30 to 58 cm.
Depth to horizons with aquic conditions: 0 to 50 cm.
Effervescence: Usually noneffervescent; some pedons have thin strata that are slightly effervescent to strongly effervescent.
Other features: Few to many mica flakes are percent, but in amounts less than 65 percent by grain count.

Particle-size control section - Clay content: 6 to 18 percent.
Rock fragments: 0 to 10 percent, mainly gravel.

A horizons
Hue: 10YR or 2.5Y.
Value: 2 or 3 moist, 4 or 5 dry.
Chroma: 1 or 2, moist or dry.
Reaction: Slightly acid or moderately alkaline.
Organic matter content: 1 to 5 percent.
Redoximorphic features: Distinct or prominent redox concentrations occur as masses of iron accumulation in some subhorizons.

AC horizon
Hue: 10YR or 2.5Y.
Value: 2 or 3 moist, 4 or 5 dry.
Chroma: 1 or 2, moist or dry.
Texture: Stratified coarse sandy loam to fine sandy loam.
Reaction: Slightly acid through moderately alkaline.
Organic matter content: 1 to 5 percent.
Redoximorphic features: Distinct or prominent redox concentrations occur as masses of iron accumulation.

Cg horizons
Hue: 2.5Y or 5Y.
Value: 2 through 4 moist, 5 or 6 dry.
Chroma: 1 through 3, moist or dry.
Texture: Stratified coarse sandy loam to fine sandy loam in upper subhorizons and stratified coarse sand to sandy loam in lower horizons; Some pedons have clay or very gravelly sand below depths of 100 cm.
Reaction: Slightly acid through slightly alkaline.
Redoximorphic features: Distinct or prominent redox concentrations occur as masses of iron accumulation; Redox depletion of iron is present as the gleyed, low chroma matrix.

COMPETING SERIES: These are the Darfur, Dassel, Gilford, Goodell, Hanska, Lyles, Monon, Mudgepond, Overshue, Toolesboro, Uniongrove, and Whitepost series.

Darfur, Dassel, Gilford, Goodell, Hanska, Lyles, Monon, Mudgepond, Overshue, Toolesboro, Uniongrove, and Whitepost soils are in areas of much higher precipitation and do not have an aridic moisture regime.

GEOGRAPHIC SETTING: Jubilee soils are on swales, flood plains, and sloughs on the toes of alluvial fans. These soils formed in alluvium derived from mixed sources but with a significant influence from granitic rocks. Slopes are 0 to 4 percent. Elevations range from 1,433 to 1,710 meters. The climate is semiarid with cool, moist winters and warm, dry summers. The mean annual precipitation is 200 to 300 mm, mean annual temperature is 8 to 11 degrees C, and the frost-free period is 90 to 110 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Ophir, Settlemeyer, and Voltaire soils. Ophir soils are sandy. Settlemeyer are fine-loamy. Voltaire soils are fine-loamy and calcareous.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Poorly drained and very poorly drained; very low to high surface runoff; high saturated hydraulic conductivity. Endosaturation is present with an apparent seasonal high water table between the soil surface and 50 cm (very shallow to moderately deep free water occurrence classes) from December through June. Cumulative annual duration classes are Common or Persistent. These soils are susceptible to occasional flooding for brief periods between December and May or rare flooding for very brief periods year-round.

USE AND VEGETATION: Jubilee soils are used for pasture and meadow hay production. The vegetation is composed of sedges, various clovers, Nevada bluegrass, beardless wildrye, meadow barley, streambank wheatgrass, and Juncus spp.

DISTRIBUTION AND EXTENT: Western Nevada. These soils are not extensive. MLRA 26.
