COMPETING SERIES: These are the
Blyburg series. Blyburg soils contain free
carbonates within a depth of 20 inches.
GEOGRAPHIC SETTING:
Parent material: coarse silty alluvium
Landform: flood plain step
Flooding: occasional to rare
Duration: brief
Slopes: 0 to 2 percent
Elevation: 780 to 1070 feet
Mean annual temperature: 52 to 55 degrees F
Mean annual precipitation: 34 to 40 inches
Soil moisture: The soil moisture control section is 4 to 12 inches; udic moisture regime.
Precipitation pattern: udic
Frost-free period: 170 to 190 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Belvue,
Bismarckgrove,
Bourbonais,
Kimo, Kiro,
Stonehouse and
Zeandale soils.
The Belvue soils are coarse-silty and have carbonates below 20 inches.
The fine-silty Bismarckgrove soils are on similar and somewhat lower positions.
The coarse-silty over sandy Bourbonais soils occur on similar landscape positions.
The clayey over loamy Kimo soils are generally on lower positions.
Kiro soils are fine textured and in depressions.
The sandy textured Stonehouse soils are generally on somewhat higher positions.
The Zeandale soils are coarse-silty and have carbonates throughout.
DRAINAGE AND PERMEABILITY:
Drainage: Well
Runoff: negligible to low
Permeability: moderate
USE AND VEGETATION: Most areas of Eudora soils are cultivated. Common cultivated crops are corn, grain, sorghum, soybeans, wheat, and alfalfa. Native vegetation is tall grasses and a few deciduous trees.
DISTRIBUTION AND EXTENT: LRR M; MLRA 106; North-central and northeastern Kansas, Missouri along the length of the Missouri River, and southeastern Nebraska. The soils of this series are of moderate extent.
