NETO SERIES


The Neto series consists of very deep, somewhat excessively drained, moderately rapidly permeable soils on stream bottoms and alluvial fans. They formed in mixed alluvium. Slopes range from 0 to 5 percent. Mean annual temperature is 44 degrees F. and the mean annual precipitation is 16 inches.

TAXONOMIC CLASS: Coarse-loamy, mixed, superactive, calcareous, frigid Typic Ustifluvents

TYPICAL PEDON: Neto sandy loam--rangeland. (Colors are for air-dry soil unless otherwise stated.)

A--0 to 2 inches; brown (10YR 5/3) sandy loam, dark brown (10YR 4/3) moist; weak fine granular structure; soft, very friable, slightly sticky; common fine roots; common fine interstitial pores; about 2 percent gravel; strongly calcareous; moderately alkaline (pH 8.0); clear smooth boundary. (1 to 12 inches thick)

C1--2 to 13 inches; pale brown (10YR 6/3) sandy loam, yellowish brown (10YR 5/4) moist; massive; slightly hard, friable; common fine and very fine roots; few fine interstitial and common fine tubular pores; strongly calcareous; moderately alkaline (pH 8.0); abrupt wavy boundary. (10 to 14 inches thick)

C2--13 to 16 inches; light brown (7.5YR 6/4) very gravelly loamy sand, brown (7.5YR 5/4) moist; single grain; loose; common very fine and few coarse roots; common medium interstitial pores; 50 percent fine gravel; very strongly calcareous; moderately alkaline (pH 8.0); abrupt wavy boundary. (1 to 4 inches thick)

C3--16 to 28 inches; brown (10YR 5/3) sandy loam, brown (10YR 4/3) moist; massive; slightly hard, friable; few fine roots; 2 percent gravel; very strongly calcareous; moderately alkaline (pH 8.0); gradual wavy boundary. (10 to 14 inches thick)

C4--28 to 38 inches; pale brown (10YR 6/3) loamy sand, yellowish brown (10YR 5/4) moist; massive; soft, friable; 5 percent gravel; strongly calcareous; moderately alkaline (pH 8.0); abrupt wavy boundary. (0 to 12 inches thick)

C5--38 to 60 inches; pale brown (10YR 6/3) extremely gravelly loamy sand, brown (10YR 4/3) moist; single grain; loose; 75 percent medium and coarse gravel; strongly calcareous; moderately alkaline (pH 8.0).

TYPE LOCATION: Garfield County, Utah; Noon Canyon; SE 1/4 sec. 26, T. 37 S., R. 4 W.

RANGE IN CHARACTERISTICS: The mean annual soil temperature is about 44 to 57 degrees F. and the mean summer soil temperature at a depth of 20 inches is about 59 to 64 degrees F. The soils are usually moist but are dry for 90 cumulative days or more in 7 out 10 years in some subhorizons between depths of 8 and 24 inches but are not continuously dry in all parts between these depths for as long as 60 consecutive days. These soils are slightly calcareous to very strongly calcareous in the A and C horizons.

The A horizon has hue of 7.5YR to 2.5Y, value of 5 or 6 dry, 3 to 5 moist, and chroma of 3 to 6.

The C horizon has hue of 7.5YR or 10YR, value of 4 to 7 dry, 3 to 6 moist, and chroma of 3 to 6. It is stratified loam, sandy loam, loamy sand, silt loam, silty clay loam, and gravelly, very gravelly or extremely gravelly loamy sand and averages less than 18 percent clay in the particle size control section.

COMPETING SERIES: These are the competing Trembles series and the Shupert and Winetti series in similar families. Trembles soils lack gravelly strata in the particle size control section. Shupert soils are in the fine-loamy family. Winetti soils are in the loamy-skeletal family.

GEOGRAPHIC SETTING: Neto soils are in long narrow nearly level bottoms and gently sloping alluvial fans at elevations of 6,600 to 8,400 feet. Slope gradients are 0 to 5 percent. These soils formed in mixed alluvium from sandstone, limestone, and shale. The average annual precipitation is 13 to 20 inches and the freeze-free period ranges from 70 to 100 days. The mean annual temperature is 42 to 45 degrees F. and the average summer temperature is 59 to 64 degrees F.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Kade soils and the competing Shupert and Winetti soils. Kade soils have over 35 percent clay in the particle size control section and have mottles within 20 inches.

DRAINAGE AND PERMEABILITY: Somewhat excessively drained; medium runoff; moderately rapid permeability.

USE AND VEGETATION: Neto soils are used for rangeland and wildlife. The native vegetation is Utah juniper, pinyon pine, big sagebrush, bitterbrush, rabbitbrush, blue grama, western wheatgrass, and needleandthread grass.

DISTRIBUTION AND EXTENT: These soils are in the south-central part of Utah. They are not extensive.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Bozeman, Montana

SERIES ESTABLISHED: Garfield County (Panguitch Soil Survey Area), Utah, 1969.

REMARKS: These soils were formerly classified as Alluvial soils. Diagnostic horizons and features recognized in this pedon are:

Ochric epipedon - the zone from the surface of the soil to 2 inches. (A horizon)

Fluvent feature - an irregular decrease in organic matter.

Ustic feature - dry in some or all parts of the moisture control section for 90 or more days cumulative, but not dry in all parts more than half the time that the soil temperature at 20 inches is 41 degrees F. or more.

The superactive cation exchange activity class was added in 03/2003 to the taxonomic classification by the National Soil Survey Center on request of the Lakewood MLRA office, without review of the soil series property data. The remainder of this document has not been updated.
