Holdrege soil series
Holdrege soil series (Nebraska State Soil)
The Holdrege series consists of very deep, well drained, moderately permeable soils formed in calcareous loess. These upland soils have slopes ranging from 0 to 15 percent. Mean annual temperature is about 54 degrees F, and mean annual precipitation is about 23 inches at the type location.
TAXONOMIC CLASS: Fine-silty, mixed, superactive, mesic Typic Argiustolls
Soil Moisture: The soil moisture control section is moist in some part from October through April; intermittently moist from May through July; driest in July through September
Depth to secondary carbonates: 20 to 40 inches
Thickness of the mollic epipedon: 8 to 20 inches; and includes the upper part of the argillic horizon in some pedons
Thickness of the solum: 20 to 40; the lower part of the solum contains free carbonates in some pedons
USE AND VEGETATION: Almost all of the Holdrege soils are cultivated and much is irrigated. Sorghum and corn are the principal row crops. Wheat is the principal small grain. Native vegetation was mid and tall prairie grasses.
DISTRIBUTION AND EXTENT: South-central Nebraska and north central Kansas. The series is of large extent.
Severely eroded Holdrege soils will no longer classify as Mollisols and will need to be recorrelated to a new series. Diagnostic horizons and features recognized in this pedon are: mollic epipedon--the zone from 0 to 15 inches (Ap, a and Bt1 horizon); argillic horizon--the zone from 12 to 24 inche4s (Bt1 and Bt2 horizons) and typic-ustic moisture regime. A sandy overblown phase is recognized.
