JENOR SERIES

The Jenor series consists of moderately deep, well drained soils that formed in alluvium from mixed rock sources with a component of loess. Jenor soils are on calderas and fan piedmont remnants. Slopes are 0 to 8 percent. The mean annual precipitation is about 180 mm and the mean annual temperature is about 9 degrees C.

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

TYPICAL PEDON: Jenor very fine sandy loam, rangeland. (Colors are for dry soil unless otherwise noted.)

(13 to 20 cm thick)

Bw--15 to 41 cm; light gray (10YR 7/2) fine sandy loam, brown (10YR 4/3) moist; weak fine subangular blocky structure; soft, very friable, nonsticky and slightly plastic; common fine and few medium oblique roots; many very fine interstitial and tubular pores; strongly alkaline (pH 8.8); clear wavy boundary. (10 to 25 cm thick)

Bk--41 to 56 cm, very pale brown (10YR 7/3) sandy loam, dark yellowish brown (10YR 4/4) moist; massive; soft, very friable, nonsticky and slightly plastic; few fine and medium oblique and horizontal roots; common very fine tubular pores; strongly effervescent; strongly alkaline (pH 8.8); clear wavy boundary. (0 to 15 cm thick)

Bqk--56 to 66 cm; very pale brown (10YR 8/3) loam, light yellowish brown (10YR 6/4) moist; massive; slightly hard, friable, nonsticky and slightly plastic; very few fine and medium roots; common very fine tubular pores; about 20 percent, 2 to 10 mm, weak durinodes; violently effervescent; strongly alkaline (pH 8.8); abrupt wavy boundary. (10 to 40 cm thick)

Bqkm1--66 to 109 cm; very pale brown (10YR 8/2) indurated silica-cemented duripan, very pale brown (10YR 7/3) moist; common fine distinct dark yellowish brown (10YR 4/4) moist iron mottles; strong medium and very thick platy structure; very hard, extremely firm; very few fine horizontal roots; few very fine tubular pores; peds have continuous 0.2 to 0.6 cm thick very pale brown (10YR 8/3) silica laminae; violently effervescent; moderately alkaline (pH 8.2); gradual smooth boundary. (15 to 50 cm thick)

Bqkm2--109 to 142 cm; very pale brown (10YR 8/2) indurated silica-cemented duripan, very pale brown (10YR 7/3) moist; few fine distinct light yellowish brown (10YR 6/4) and dark yellowish brown (10YR 4/4) moist iron mottles; strong thick platy structure; very hard, extremely firm; common very fine tubular pores; plate surfaces have up to 0.3 cm thick silica laminae; violently effervescent; moderately alkaline (pH 8.2); gradual smooth boundary. (0 to 33 cm thick)

Bqkm3--142 to 152 cm; very pale brown (10YR 8/2) indurated silica-cemented duripan very pale brown (10YR 7/4) moist; strong very thick platy structure; very hard, extremely firm; common very fine tubular pores; plate surfaces have up to 2 mm thick very pale brown (10YR 7/3) and pale brown (10YR 6/3) moist silica laminae; violently effervescent; moderately alkaline (pH 8.2).

TYPE LOCATION: Lander County, Nevada; approximately 12 miles north of Battle Mountain, about 1,050 feet north and 1,050 feet east of the southwest corner of section 17, T. 34 N., R. 45 E.; USGS Russells 7.5 minute topographic quadrangle; latitude 40 degrees 49 minutes 04 seconds N and longitude 116 degrees 56 minutes 14 seconds W; WGS84 Decimal Degrees 40.8177778 latitude, -116.9372222 longitude.

RANGE IN CHARACTERISTICS:
Soil moisture - Usually dry, moist in some part for short periods from late October through May; aridic soil moisture regime.
Mean annual soil temperature: 8 to 11 degrees C.
Depth to indurated duripan: 50 to 76 cm.
Reaction: Moderately alkaline or strongly alkaline.

Particle-size control section - Clay content: 8 to 18 percent.
Rock fragments: Up to 25 percent, mainly gravel.

A horizon
Value: 6 or 7 dry, 4 or 5 moist.
Chroma: 2 or 3.
Consistence: Soft or slightly hard dry, friable or very friable moist.

Bw horizon
Value: 6 or 7 dry, 4 or 5 moist.
Chroma: 2 through 4.
Texture: Fine sandy loam or loam.
Structure: Weak or moderate, medium or coarse subangular blocky or horizon is massive.

Bqk horizon
Value: 7 or 8 dry, 4 through 6 moist.
Chroma: 3 through 6.

Rock fragments: Up to 25 percent, mainly gravel.
Carbonates: Strongly effervescence or violently effervescence.
Other features: Up to 10 percent pan fragments near the Bqk horizon boundary in some pedons.

COMPETING SERIES: This is the Jolan series. Jolan soils have a mean annual soil temperature of 11 to 14 degrees C. and are moist in some part of the soil moisture control section for short periods during the summer months.

GEOGRAPHIC SETTING: Jenor soils are on calderas and fan piedmont remnants. These soils formed in alluvium from mixed rock sources with a component of loess. Slopes are 0 to 8 percent. Elevations are 1,160 to 1,710 meters. The climate is cool, arid with hot, dry summers and cool, moist winters. The mean annual precipitation is 130 to 250 mm; mean annual temperature is 7 to 10 degrees C., and the frost-free season is 95 to 120 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Beoska, Blacka, Broyles and Chiara soils. Beoska soils lack an indurated duripan and have a fine loamy Bt horizon. Blacka soils have a strongly cemented duripan. Broyles soils are very deep and lack an indurated duripan. Chiara soils are less than 50 cm to the indurated duripan.

DRAINAGE AND PERMEABILITY: Well drained; slow or medium runoff; moderately rapid permeability.

USE AND VEGETATION: Livestock grazing and wildlife habitat. The present vegetation is mainly shadscale, bud sagebrush, bottlebrush squirreltail and Indian ricegrass.

DISTRIBUTION AND EXTENT: North-central Nevada and Southwest Idaho. These soils are not extensive. MLRA 24 and 25.
