Scobey soil and landscape
Soil profile: A representative soil profile of the Scobey series near Glasgow MT; the State Soil of Montana.
Landscape: Productive rangelands provide for livestock grazing and dry land farming produces high-quality wheat. (Photo provided by Janice Hendrickson)
In 1928, the Scobey series was established in the Milk River Area, located in the northern plains of Montana. The series was named for the northeastern Montana town of Scobey and used to represent dark grayish-brown farming soils. The Scobey soil was designated
the official Montana state soil in 2015.
The Scobey series consists of very deep, well drained soils that formed in till. These soils are on till plains, hills, and moraines. Slopes are 0 to 15 percent. Mean annual precipitation is about 12 inches, and the mean annual air temperature is about 43 degrees F.
TAXONOMIC CLASS: Fine, smectitic, frigid Aridic Argiustolls
Soil temperature - 42 to 47 degrees F.
Moisture control section - between 4 and 12 inches; dry in all parts between four-tenths and five-tenths of the cumulative days per year when the soil temperature at a depth of 20 inches is 41 degrees F or higher.
Mollic epipedon thickness - 7 to 16 inches.
Depth to Bk horizon - 10 to 18 inches.
Depth to Bky or By horizon - 30 to 55 inches.
Btk, By, or BC horizons are allowed.
Phases- stony, shaley substratum.
USE AND VEGETATION: Scobey soils are used mainly for dryland crops. Some areas are used as rangeland. Potential native vegetation is mainly bluebunch wheatgrass, western wheatgrass, green needlegrass, and needleandthread.
DISTRIBUTION AND EXTENT: Scobey soils are extensive in the till plains of northern Montana.
