COMPETING SERIES: These are the Glendora, Kanza, Kingsville, Marlake, Plev, Tobico and Vestaburg series. Glendora soils formed in forested continental climate, have Cg horizons and contain less than 3 percent gravel throughout the profile. Kanza soils formed from well sorted eolian fine sands and have mean annual soil temperature of 56 to 58 degrees F. Kingsville soils formed in forested continental climate, have Bg horizons, less than 10 percent gravel within the substratum and average annual soil temperature of 50 to 53 degrees F. Marlake soils formed in forested continental climate, have Oe horizons, carbonates between 0 and 15 inches and slightly alkaline Cg horizons. Plev soils formed in forested continental climate, have Cg and 2Btgb horizons and average annual soil temperature of 57 to 59 degrees F. Tobico soils formed in forested continental climate, have Cg horizons and calcium carbonate in the upper 15 inches. Vestaburg soils formed in forested continental climate, have Cg horizons and calcium carbonate between 20 and 40 inches.
GEOGRAPHIC SETTING: Pay soils are on flood plains of rivers and streams at elevations of 2,950 to 3,700 feet. These soils formed in alluvium from igneous rocks (dominantly granodiorite). Slopes range from 0 to 1 percent. The average annual precipitation is 20 to 26 inches. The average annual temperature is 45 to 48 degrees F. The frost-free period is 90 to 120 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Crossbow, Foxlane and Ralsen soils. Crossbow soils have cumulic mollic epipedons, are coarse-loamy and somewhat poorly drained. Foxlane soils have mollic epipedons, are sandy-skeletal and moderately well drained. Ralsen soils have mollic epipedons and are coarse-loamy. These soils occur on adjacent flood plain steps.
DRAINAGE AND PERMEABILITY: Poorly drained with a high water table at the surface to a depth of 20 inches during April and May; very slow runoff; rapid permeability. Pay soils are subject to occasional flooding for brief to long periods in December through June.
USE AND VEGETATION: Pay soils are used mainly for wildlife habitat and mountain wet meadow pastureland. Native vegetation is willows, tufted hairgrass, sedges and rushes.
DISTRIBUTION AND EXTENT: West-central Idaho. MLRA 44. Pay soils are of small extent.
