COMPETING SERIES: These are the
Goshen,
Johnstown,
Kinsell,
Kuma,
Lazarus,
Mobridge,
Simpatico and
Zepol soils.
Goshen, Johnstown, Kinsell, Kuma, Lazarus, Mobridge and Simaptico soils have a drier climate.
Zepol soils have small amounts of volcanic ash in the course silt and fine sand fraction.
GEOGRAPHIC SETTING:
Parent material: loess and allivium
Landscape: stream terraces and uplands
Slope: commonly less than 2 percent (but ranges from 0 to 6 percent)
Many of the stream terraces have a component of loess on the surface.
Mean annual precipitation: 51 to 71 centimeters (20 to 28 inches)
Mean annual temperature: 10 to 13 degrees C. (49 to 55 degrees F.)
GEOGRAPHICALLY ASSOCIATED SOILS: Associated soils on the same landscape are the
Detroit,
Hastings,
Holder,
Holdrege,
Hord,
Muir and
Wood River soils.
Detroit, Hastings and Wood River soils are in the fine family.
Hastings, Holder, Holdrege and Wood River soils have a thinner mollic epipedon.
Holder and Muir soils lack an argillic horizon.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage: well drained
Runoff: low to moderately high
Saturated Hydraulic Conductivity: moderately high
USE AND VEGETATION: Nearly all the acreage is in cultivated cropland.
Much of the cropland is irrigated.
Corn, grain sorghum, soybeans, and alfalfa are the principal crops.
A small acreage is still in native grass, mainly mid and tall species.
DISTRIBUTION AND EXTENT: Central Nebraska and possibly north-central Kansas. The series is extensive.
MLRA OFFICE RESPONSIBLE: Salina, Kansas
