INCY SERIES
The Incy series consists of very deep, excessively drained soils that formed in eolian sand derived mainly from granitic rocks. Incy soils are on semi-stabilized dunes superimposed on basin floor remnants, alluvial fans, and hills. Slopes are 0 to 30 percent. The mean annual precipitation is about 280 mm and the mean annual temperature is about 10 degrees C.
TAXONOMIC CLASS: Mixed, mesic Xeric Torripsamments
TYPICAL PEDON: Incy fine sand--rangeland. (Colors are for dry soil unless otherwise noted.)
A--0 to 10 cm; pale brown (10YR 6/3) fine sand, dark grayish brown (10YR 4/2) moist; single grain; loose, nonsticky and nonplastic; many very fine interstitial pores; neutral (pH 7.0) clear smooth boundary. (0 to 25 cm thick)
C--10 to 152 cm; pale brown (10YR 6/3) fine sand, dark grayish brown (10YR 4/2) moist; single grain; loose, nonsticky and nonplastic; many very fine and fine roots; many very fine interstitial pores; neutral (pH 7.0).
TYPE LOCATION: Carson City County, Nevada; about 7 miles southeast of Carson City near the Carson City-Douglas County line; about 100 feet east and 500 feet north of the southwest corner of section 12, T. 14 N., R. 20 E.; USGS McTarnahan Hill 7.5 minute topographic quadrangle; latitude 39 degrees 05 minutes 08 seconds N and longitude 119 degrees 41 minutes 43 seconds W; WGS84 Decimal Degrees 39.0855556 latitude, -119.6952778 longitude.

COMPETING SERIES: These are the
Berent,
Goldrun,
Grandora,
Hotsprings,
Lachim,
Painter,
Quincy,
Quinton,
Rinquin,
Toll,
Walco,
Winchester, and
Zorravista series.
Berent and
Goldrun soils are calcareous throughout.
Grandora soils have Bt horizons with clay films.
Hotsprings soils average 20 to 35 percent fine pebbles in the particle-size control section.
Lachim,
Painter, and
Rinquin soils are moderately deep to paralithic contacts.
Quincy soils are calcareous in some part, formed in parent material derived from basalt, and have dark basaltic mineral grains.
Quinton and
Walco soils are moderately deep to lithic contacts.
Toll soils formed in alluvium and have mainly loamy sand in the particle-size control section.
Winchester soils average more than 75 percent very coarse sand through medium sand which are dark basaltic mineral grains.
Zorravista soils are calcareous throughout and have significant content of volcanic glass.
GEOGRAPHIC SETTING: Incy soils are on semi-stabilized dunes superimposed on basin floor remnants, alluvial fans, and hills. Local relief is often ridged and hummocky. These soils formed in eolian sands derived mainly from granitic rocks. Slopes are 0 to 30 percent. Elevations range from 1,250 to 1,707 meters. The climate is semiarid with cool, moist winters and warm, dry summers. The mean annual precipitation is 200 to 300 mm, the mean annual temperature is 7 to 11 degrees C, and the frost-free period is 60 to 130 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Glenbrook soil and the competing
Toll soil. Glenbrook soils are shallow to paralithic contacts of granite.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Excessively drained; negligible or very low surface runoff; very high saturated hydraulic conductivity.
USE AND VEGETATION: Incy soils are used for rangeland and wildlife habitat. The present vegetation is mainly antelope bitterbrush, Anderson's peachbrush, Wyoming big sagebrush, Indian ricegrass, and bottlebrush squirreltail. These soils are also a source of sand for construction materials. This pedon is correlated to R026XY014NV, Dune 10-12" P.Z.
DISTRIBUTION AND EXTENT: Western Nevada and northeastern California. These soils are moderately extensive. The series concept and main acreage occurs in MLRA 26. Other acres of this series are mapped in MLRAs 21 and 23.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Davis, California.
