LAS SERIES
Page 1 of 2
The Las series consists of deep, somewhat poorly drained soils formed in alluvium on flood plains and low stream
terraces. These soils have moderately slow permeability, and slopes are less than 1 percent. Mean annual precipitation is
about 16 inches, and the mean annual temperature is about 54 degrees F.
TAXONOMIC CLASS: Fine-loamy, mixed, superactive, calcareous, mesic Aquic Ustifluvents
TYPICAL PEDON: Las clay loam -cultivated. (Colors are for dry soil unless otherwise stated.)
A--O to 12 inches; grayish brown (1 OYR S/2) clay loam, dark grayish brown (1 OYR 4/2) moist; weak granular structure;
hard, firm; slight effervescence; mildly alkaline; gradual smooth boundary. (5 to 15 inches thick)
C1--12 to 24 inches; light brownish gray (1 OYR 6/2) clay loam, dark grayish brown (I OYR 4/2) moist; few thin strata of
sandy loam; massive; very hazd, firm; strong effervescence; moderately alkaline; gradual smooth boundary. (8 to 20
inches thick)
C2--24 to 45 inches; light brownish gray (1 OYR 6/2) clay loam, grayish brown (1 OYR S/2) moist; common medium
distinct yellowish brown and strong brown mottles; massive; very hard, firm; stratified layers of sandy loam; coarser
textured materials occur in lower part of horizon; strong effervescence; moderately alkaline; gradual smooth boundary.
(10 to 30 inches thick)
2C3--45 to 75 inches; very pale brown (1 OYR 7/3) coarse sand and fine gravel; single grained; loose; slight effervescence;
moderately alkaline.
TYPE LOCATION: Hamilton County, Kansas; about 5 3/4 miles west and 1 mile north of Syracuse; 1,200 feet east and
100 feet north of the southwest corner of sec. 31, T. 23 S., R. 41 W.

RANGE IN CHARACTERISTICS: The thickness of the solum ranges from S to 15 inches. These soils typically have
free carbonates throughout; however, in some pedons the upper 6 inches are noncalcazeous. Reaction is mildly alkaline or
moderately alkaline throughout. The upper horizons may contain soluble salts. _ ~
IThe A horizon has hue of l OYR or 2.SY, value of S or 6 and 3 to 5 moist, and chroma of 2 or 3. If value is S and 3 moist,
the A horizon is less than 7 inches thick. It is loam, fine sandy loam, or clay loam._
C horizon has hue of l OYR, value of 5 to 7 and 4 or 5 moist, and chroma of 2 or 3. It is loam, clay loam, sandy clay
~, or sandy loam and commonly contains thin sandy or clayey strata. The lower part of the C horizon is mottled with
rs of higher chroma. Some pedons have AC horizons having color and texture like the C horizon.
re 2C horizon has hue of l OYR, value of 6 or 7 and 4 or 5 moist, and chroma of 2 to 4. It is loamy sand, fine sand, sand,
coarse sand, typically containing some gravel. Mottles are faint through prominent or lacking. Depth to the 2C horizon
more than 40 inches.
;TING SERIES: These are the Tefton and Werlo¢ series in the same family and the Angelus, Caruso, Las
Lesho, Sweetwater, and Uncompaha_re soils. The Tefton soils have a mean annual soil temperature of less than 50
