Lewhand soil series
Soil profile: Typical profile of a Lewhand soil. The ochric epipedon extends from the surface to a depth of 20 centimeters (A horizon). (Soil Survey of Clearwater Area, Idaho; by Glenn Hoffman, Natural Resources Conservation Service)
The Lewhand series consists of shallow to a fragipan, poorly drained soils formed in mixed alluvium with an admixture of volcanic ash. Permeability is very slow and slopes range from 0 to 3 percent. The average annual precipitation is about 35 inches and the average annual temperature is about 42 degrees F.
TAXONOMIC CLASS: Fine-silty, mixed, active, frigid Vitrandic Fragiudalfs
Depth to fragipan - 13 to 19 inches
Average annual soil temperature - 39 to 45 degrees F. (Frigid temperature regime)
Soil moisture control section - not dry for 45 consecutive days following the summer solstice. Aquic conditions from November to June. Udic moisture regime.
USE AND VEGETATION: Used mainly for livestock grazing, watershed and some crop production. The main crops are hay and oats. Potential native vegetation is black hawthorn, scattered lodgepole pine, snowberry, sedges and rushes.
DISTRIBUTION AND EXTENT: North central Idaho; Lewhand soils are not extensive.
