COMPETING SERIES:
Currently there are no competing series.
GEOGRAPHIC SETTING:
Parent Material: residuum of weathered acid fissile shale
Landform: erosional shale uplands
Slope: 3 to 30 percent
Mean annual temperature: 50 to 57 degrees F
Mean annual precipitation: from 18 to 24 inches
Thornthwaite Annual P-E index: 36 to 42
GEOGRAPHICALLY ASSOCIATED SOILS:
These are the
Armo,
Corinth,
New Cambria,
Solomon, and
Timken soils.
Armo, Corinth, and Timken soils are on nearby uplands.
Armo soils are fine-loamy.
Corinth soils have higher chromas and have formed in residuum of weathered calcareous chalky shale.
New Cambria and Solomon soils are in nearby narrow drainageways or on nearby terraces along major streams.
DRAINAGE AND PERMEABILITY:
Drainage: moderately well drained
Runoff: rapid
Permeability: very slow.
USE AND VEGETATION: Bogue soils are used primarily for native range. The principal species are big bluestem, little bluestem, sideoats grama, and lead plant.
DISTRIBUTION AND EXTENT: North-central Kansas. Series is of moderate extent.
