TYPE LOCATION: Sanpete County, Utah; 200 yards north of Palisade Lake on the north side of the fence; 1,500 feet east and 1,000 feet south of the northwest corner of sec. 35, T. 18 S., R. 2 E.; latitude 39 degrees 12 minutes 34 seconds N and longitude 111 degrees 39 minutes 59 seconds W; NAD83.
RANGE IN CHARACTERISTICS:
Soil moisture - The soils are usually dry; moist in winter and spring and for brief periods in late summer due to convection storms (aridic bordering on xeric soil moisture regime).
Mean annual soil temperature - 8.5 to 12.0 degrees C.
Mean annual summer soil temperature - 19.0 to 21.0 degrees C.
Particle-size control section:
Clay content: 10 to 18 percent
Sand content: 5 to 15 percent coarser than very fine sand
A horizons - Hues: 10YR or 7.5YR.
Value: 4 to 7 dry, 4 to 6 moist.
Chroma: 2 to 4, dry or moist.
Structure: Platy, subangular blocky, or prismatic.
Consistence: Soft to slightly hard dry and friable to very friable moist.
Effervescences: Slightly effervescent to strongly effervescent.
Reaction: Moderately alkaline to strongly alkaline.
C horizons - Hue of 10YR, 7.5YR or 5YR.
Value: 5 to 7 dry, 4 to 6 moist.
Chroma of 2 to 6, dry or moist.
Texture: Very fine sandy loam or silt loam.
Clay content: 10 to 18 percent clay and contains 5 to 15 percent sand coarser than very fine sand.
Structure: Massive or platy.
Consistence: Soft or slightly hard dry, very friable to friable moist, and slightly sticky to moderately sticky and slightly plastic to moderately plastic wet.
Reaction: Moderately alkaline to strongly alkaline.
Calcium carbonate equivalent: 10 to 40 percent.
COMPETING SERIES: These are Kennewick (WA), Pocatello (ID), Ritzcal (WA) and Wheeler (ID) series. Kennewick, Pocatello and Ritzcal soils have visible carbonates within the series control section. Ritzcal soils also are formed in loess. Wheeler soils have visible gypsum within the series control section.
GEOGRAPHIC SETTING: Linoyer soils are on nearly level to moderately sloping fan remnants, alluvial fans, alluvial flats, basin floor, fan skirts, inset fans, axial stream terraces, lake terraces and lake plains at elevations of 1,370 to 1,830 meters in Utah and up to 2,130 meters in Nevada. Slopes are 0 to 10 percent. They formed in alluvium and lacustrine deposits derived from sandstone and limestone. The climate is semiarid and the average annual precipitation ranges from 200 to 300 cm. Mean annual air temperature ranges from 7.0 to 11.0 degrees C. Frost-free period is 100 to 140 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Arapien, Centerfield, Dyreng, Lisade, Sanpete and Sigurd soils. Arapien, Centerfield, Lisade, Sanpete and Sigurd soils have more than 40 percent carbonates in the series control section. Sanpete and Sigurd soils contain more than 35 percent coarse fragments. Dyreng soils have more than 35 percent clay in the particle-size control section.
DRAINAGE AND PERMEABILITY: Well drained; low or medium runoff; moderate permeability; moderately high to high saturated hydraulic conductivity.
USE AND VEGETATION: These soils are used for irrigated crops of alfalfa, small grains, corn and pasture. They are also used for livestock grazing. Potential vegetation is winterfat, Indian ricegrass, Wyoming big sagebrush and basin big sagebrush. These soils are correlated to semidesert ecological sites in Utah.
DISTRIBUTION AND EXTENT: Central Utah and Nevada. The series is extensive, with 165,528 acres mapped to date. MLRA 28A and 28B.
MLRA OFFICE RESPONSIBLE: Reno, Nevada
SERIES ESTABLISHED: Sanpete Area, Utah, 1971.
