Ethridge soil series
The Ethridge series consists of very deep, well drained soils that formed in alluvium and glaciofluvial deposits from mixed rock sources, and/or in till and lacustrine deposits. These soils are on alluvial fans, fan remnants, stream terraces, drainageways, hills, sedimentary plains, lake plains, and till plains. Slopes are 0 to 35 percent. Mean annual precipitation is about 305 cm. Mean annual air temperature is about 6.7 degrees C.
TAXONOMIC CLASS: Fine, smectitic, frigid Torrertic Argiustolls
Soil temperature - 5.6 to 8.3 degrees C.
Moisture control section - between 10 and 30 cm; dry in some part for six tenths or more of the cumulative days per year when the soil temperature at a depth of 50 cm is 5 degrees C. or higher.
Mollic epipedon thickness - 18 to 36 cm and may include all or only part of the Bt horizon.
Depth to Bk horizon - 25 to 61 cm.
A Btk horizon is allowed.
USE AND VEGETATION: Ethridge soils are used for nonirrigated crops and for range. The potential plant community is green needlegrass, bluebunch wheatgrass, western wheatgrass, forbs, and shrubs.
DISTRIBUTION AND EXTENT: The Ethridge series is extensive in the plains area of Montana and western North Dakota. MLRAs 44B, 46, 52, 58A, 58C, and 60B.
