TYPE LOCATION: Sanpete County, Utah; about 2 miles east and 1 1/4 miles north of Axtell, and about 1,500 feet east of the Highline Canal; about 3,000 feet east and 1,070 feet south of the NW corner of sec. 15, T.20S., R.lE.; USGS Redmond, Utah 7.5 minute quadrangle; latitude 39 degrees 4 minutes 28 seconds north and longitude 111 degrees 47 minutes 20 seconds west; NAD 83.
RANGE IN CHARACTERISTICS:
Soil moisture: 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: 8.0 to 12.0 degrees C.
Depth to the base of the calcic horizon: 76 to 130 cm.
Particle-size control section (weighted average):
Clay content: 12 to 18 percent.
Sand content: More than 15 percent coarser than very fine sand
Rock fragments: 10 to 35 percent, mainly gravel.
Calcium carbonate equivalent: Averages 40 to 60 percent (including coarse fragments less than 20 millimeters in size[r1]).
A horizon:
Hue: 10YR or 7.5YR
Value: 6 or 7 dry, 4 or 5 moist
Chroma: 2 through 4
Reaction: moderately alkaline or strongly alkaline
Bk and C horizons:
Hue: l0YR through 5YR
Value: 6 through 8 dry, 5 through 7 moist
Chroma: 2 through 6
Texture: Most commonly loam and sandy loam; less commonly very fine sandy loam, fine sandy loam, or silt loam
Clay content: Less than 18 percent
Reaction: moderately alkaline or strongly alkaline
Rock fragment content: Averages 10 to 35 percent; upper subhorizons range from 0 to 15 percent.
Calcium carbonate equivalent: 40 to 60 percent in the upper part; lower Bk and C horizons range from 20 to 40 percent.
COMPETING SERIES: There are no other series in this family.
GEOGRAPHIC SETTING: Lisade soils are on gently to moderately sloping alluvial fans, alluvial flats, fan skirts or plains at elevations of 1,525 to 1,975 meters. They formed in alluvium from limestone, sandstone, and shale. The climate is semiarid. Mean annual temperature ranges from 7.0 to 10.5 degrees C. Average annual precipitation ranges from 200 to 300 millimeters. Frost-free period is 100 to 140 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Amtoft, Genola, Rapho, and Sanpete soils and the competing Arapien soils. Amtoft soils are less than 20 inches deep over limestone bedrock. Genola soils have less than 40 percent carbonates in the control section. Rapho soils lack calcic horizons and have 20 to 35 percent coarse fragments in the control section. Sanpete soils have more than 35 percent coarse fragments in the control section.
DRAINAGE AND PERMEABILITY: Somewhat excessively drained; medium to low runoff; moderately rapid permeability; high saturated hydraulic conductivity.
USE AND VEGETATION: These soils are used for rangeland and for irrigated alfalfa, small grain corn and pasture. Principal native vegetation is Indian ricegrass, yellowbrush, shadscale, big sagebrush, rabbitbrush and snakeweed.
DISTRIBUTION AND EXTENT: Central Utah. The series is inextensive. MLRA 28A.
MLRA OFFICE RESPONSIBLE: Reno, Nevada
SERIES ESTABLISHED: Sanpete Area, Utah, 1971.
REMARKS: These soils were formerly classified as Calcisols.
