KODAK SERIES

The Kodak soils are well-drained, medium-textured Regosols developed on local aeolian deposits in cool desert areas. The deposits have blown from local Lovelock soils and from beach, marsh, lake, and stream deposits near the margin of Humboldt Lake. They have been accumulated on the surface of Lovelock soils and range from moderately deep to deep over Lovelock soil material. Because a fluctuating water table usually occurs within a depth of 60 inches, all mapping units are imperfectly drained. The present cover, and probably that during the accumulation and development of this soil, consist of moderately dense stand of heliotrope (Heliotropism curassavicum), and suada plants not eaten by livestock.

Kodak soil material is gray to dark gray, moderately permeable, very strongly calcareous, moderate in content of organic matter, high in soluble salts, and contains many mollusks shell fragments.

These soils are associated with those of Lovelock loam, they remotely resemble the Preston and the proposed Star Peak soils, but differ greatly in color, mineralogy and organic matter content.

The Kodak soils occur at elevations of about 3,950 feet in an arid continental climate having a mean annual precipitation of about 4 inches, with warm summers and cool winters; an average January temperature of 29 degrees F., and a mean annual temperature of 55 degrees F. The average frost-free growing season is 105 days. About 150 acres of Kodak soils, all of which are two-story, are mapped in the Lovelock area, Nevada.

TAXONOMIC CLASS: Coarse-loamy, mixed, superactive, mesic Torrifluventic Haploxerolls

TYPICAL PEDON: Kodak loamy fine sand, moderately deep over Lovelock soil material, 0-2 percent slopes.

C11--0 to 4 inches; gray (10YR 5/1) coarse-textured fine sandy loam, very dark gray (10YR 3/1) moist; weak very coarse platy; slightly hard, very friable, nonsticky, nonplastic; many coarse roots; low bulk density; many white mollusk shell fragments; moderately permeable; very strongly calcareous; pH of 1 to 5 dilution 9.2; abrupt' smooth boundary. 3 to 10 inches thick.

C12--4 to 9 inches; similar to surface soil in colors loamy fine sand; massive structure; loose, very friable, nonsticky, nonplastic; many coarse roots; moderately rapid permeability; low bulk density; 10 to 15 percent white mollusk shell fragments; very strongly calcareous; pH of 1 to 5 dilution 8.8; abrupt smooth boundary. 4 to-10 inches thick.

C13-- 9 to 27 inches; similar to the horizon above, but of fine sandy loam texture; abrupt smooth boundary. 10 to 20 thick.

C14--27 to 31 inches; gray (10YR 5/1) very fine sandy loam, dark gray (10YR 4.5/1) moist; massive structure slightly hard, very friable, nonsticky, nonplastic; many fine fibrous roots; low bulk density; few white mollusk shell fragments; very strongly calcareous; pH of 1 to 5 dilution 8.8; abrupt smooth boundary. 3 to 10 inches thick.

A11b--31 to 60 inches; gray (N 6/0) silt loam, dark gray (N 4/0) moist; massive in place but breaks with ease to weak coarse fine subangular blocky aggregates; slightly hard, friable, slightly sticky, nonplastic; many very fine roots; very high in organic matter; low bulk density; few very fine tubular pores; very strongly calcareous; few white mollusk shell fragments; pH of 1 to 5 dilution 8.6.

TYPE LOCATION: 90 feet east and 620 feet south of apparent w 1/4 corner, section 35, T. 25 N., R. 30 E.

RANGE IN CHARACTERISTICS: Depths of Kodak soil over buried Lovelock soil material range from 20 to about 40 inches. The buried material is usually stratified and from loam to clay in texture. Light gray mottling of lime and black organic stains occur in the buried soil material in places.

GEOGRAPHIC SETTING: Kodak soils are on broad hummocks 12 to 20 inches high on a nearly level deltaic plain.

DRAINAGE AND PERMEABILITY; Areas where this soil occurs are imperfectly drained. A fluctuating water table may rise to within 4 to 6 feet of the surface. The Kodak soil material is genially less than 4 feet deep and to this depth drainage is good. Permeability is moderate.

USE AND VEGETATION: None of this soil has been developed for growing irrigated crops but probably will be as soon as adequate drainage becomes effective. A rather dense stand of heliotrope 8 to 12 inches high covers virgin areas.

DISTRIBUTION AND EXTENT: About 150 acres mapped in the Lovelock area, Nevada. Similar soil may occur elsewhere but it has not been observed.

MLRA OFFICE RESPONSIBLE: Reno, Nevada

SERIES PROPOSED: Lovelock soil survey area, Pershing County, Nevada, 1957 .

REMARKS: Kodak is the name of a local railroad station.

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 Reno MLRA office, without review of the soil series property data. The remainder of this document has not been updated.
