Sogn soil series
A representative soil profile of the Sogn series. The shallow, clayey Sogn soils formed directly over limestone. (Soil Survey of Tallgrass Prairie National Preserve, Kansas; United States Department of Agriculture, Natural Resources Conservation Service, and United States Department of the Interior, National Park Service).
The Sogn series consists of shallow and very shallow, somewhat excessively drained, soils that formed in residuum weathered from limestone. Sogn soils are on hillslopes on uplands in Bluestem Hills, MLRA 76. Slopes range from 0 to 45 percent. Mean annual precipitation is about 840 millimeters (33 inches), and mean annual temperature is about 13 degrees C (55 degrees F) at the type location.
TAXONOMIC CLASS: Clayey, mixed, superactive, mesic Lithic Haplustolls
Soil moisture regime: Ustic bordering on Udic
Soil temperature regime: mesic
Mollic epipedon thickness: 10 to 49 centimeters (4 to 20 inches)
Depth to lithic contact: 10 to 49 centimeters (4 to 20 inches)
Particle-size control section (weighted average):
Clay content: 35 to 44 percent
Sand content: 2 to 14 percent
Rock fragments: 0 to 34 percent limestone gravels and channers
Some pedons do not contain free carbonates above the bedrock.
USE AND VEGETATION: Almost all areas are used for rangeland. Native vegetation is a tall-and mid-grass prairie. Sideoats grama, big bluestem, and little bluestem are dominant.
DISTRIBUTION AND EXTENT: Mostly in eastern Kansas, and widely spaced small areas are in western Missouri, eastern Iowa and Nebraska, northwestern Illinois, southeastern South Dakota, southern Minnesota, and southwestern Wisconsin..The Sogn series is extensive.
