TYPE LOCATION: McPherson County, Kansas; 2 miles west and 1/2 mile south of Goessel; 2,490 feet west and 2,640 feet north of the southeast corner of sec. 11, T. 21 S., R. 1 W.
RANGE IN CHARACTERISTICS:
Solum thickness: 30 to 55 inches
Depth of the mollic epipedon: 20 to 50 inches
Particle-size control section (weighted average):
Clay content: 39 to 53 percent
Note: Free carbonates in the form of films, threads, or soft concretions and iron manganese concretions are at depths greater than 15 inches in some pedons.
A horizon:
Hue: 10YR
Value: 3 or 4 and 2 or 3 moist
Chroma: less than 1.5
Texture: is silty clay loam or clay in some pedons
Clay content:
Reaction: slightly acid or neutral
AC horizon:
Hue: 10YR to 5Y
Value: 3 to 6 and 2 to 4 moist
Chroma: 1 or 2
Texture: silty clay or clay
Reaction: moderately alkaline
Note: Most pedons have reddish or brownish mottles. Slickensides or wedge shaped peds or both occur in most pedons. Vertical tonguing less than 4 inches in width of the dark clayey surface soil extends to depths of 35 inches in some pedons.
C horizon:
Hue: 10YR or 2.5Y
Value: 3 to 6 and 2 to 5 moist
Chroma: 1 to 4
Texture: silty clay, clay, or clay loam
Note: Most pedons have reddish or brownish mottles. Gypsum crystals occur as nests and seams in some pedons.
COMPETING SERIES:
Currently the
Millboro series is the only competor.
Millboro soils have a mollic epipedon and an argillic horizon.
GEOGRAPHIC SETTING:
Parent Material: clayey alluvium
Landform: nearly level to gently sloping high terraces and uplands
Slope: 0 to 3 percent
Mean annual temperature: 55 to 57 degrees F.
Mean annual precipitation: 28 to 32 inches
Thornwaite Annual P-E Index ranges from 48 to 54.
Note: In areas of native grass, gilgai are common.
GEOGRAPHICALLY ASSOCIATED SOILS:
These are the
Rosehill,
Irwin,
Ladysmith, and
Tabler soils.
Rosehill and Irwin soils are on plane to convex slopes below Goessel soils.
Ladysmith and Tabler soils are on similar nearby landscapes.
Irwin, Ladysmith, and Tabler soils have argillic horizons.
In addition, Tabler is thermic.
DRAINAGE AND PERMEABILITY:
Drainage: moderately well drained
Runoff: low or medium
Permeability: very slow.
USE AND VEGETATION: About four-fifths is cropped to wheat and sorghum. The remainder is used as grazing land. Native vegetation is mid or tall grass prairie.
DISTRIBUTION AND EXTENT: Central Kansas. The series is moderately extensive with an estimated area of 70,000 acres.
MLRA OFFICE RESPONSIBLE: Salina, Kansas
SERIES ESTABLISHED: Marion County, Kansas, 1930.
