Palouse soil and landscape
Palouse soils are on hills at elevations of 1,600 to 4,500 feet. Slopes are 0 to 60 percent. These soils formed in Late Wisconsin loess which contains some volcanic ash in the upper part. Summers are warm and dry; winters are cool and moist. The average annual precipitation ranges from 18 to 25 inches. Average January temperature is 27 to 30 degrees F, average July temperature is 67 to 70 degrees F. The mean annual temperature ranges from 46 to 51 degrees F. and on the average frost-free season is about 100 to 160 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Caldwell, Garfield, Gwin, Latah, Latahco, Mondovi, Naff, Thatuna, Tilma, and Waha soils. Caldwell and Mondovi soils have irregular distribution of organic matter with depth. Garfield soils have an ochric epipedon and have a fine argillic horizon. Gwin soils have a lithic contact at 10 to 20 inches. Latah and Tilma soils have a fine textured argillic horizon. Latahco soils are frigid. Naff and Thatuna soils have an argillic horizon. Waha soils are fine-loamy and have a lithic contact at 20 to 40 inches.
DRAINAGE AND PERMEABILITY: Well drained; slow to rapid runoff; permeability is moderate.
USE AND VEGETATION: Used mainly for dryland cropland. Small grains, peas, lentils, alfalfa, and grasses for hay and pasture are common crops. Native vegetation is Idaho fescue, bluebunch wheatgrass, Sandberg bluegrass, arrowleaf balsamroot, common snowberry, and wild rose.
DISTRIBUTION AND EXTENT: Southeastern Washington, northeastern Oregon, and northern Idaho. Series is extensive.
