Ager soil series
The Ager series consist of deep, well drained soils that formed in lacustrine sediment. Ager soils are on terraces. Slopes range from 2 to 60 percent. The mean annual precipitation is about 12 inches and the mean annual temperature is about 48 degrees F.
TAXONOMIC CLASS: Very-fine, smectitic, mesic Chromic Haploxererts
Depth to a paralithic contact of mudstone or siltstone lake deposits is 40 to 60 inches. Depth to secondary carbonates is less than 10 inches. The mean annual soil temperature is about 50 to 55 F. The soil between depths of 4 to 12 inches is usually dry all of the time from July 15 until October 15 and is moist in some or all parts all the rest of the year. The soil has cracks that open and close once each year, remain open during the period of July through October and remain closed the rest of the year. Few to many intersecting slickensides occur in the lower A horizon. Rock fragments range to 25 percent of the surface horizon and occur just on the surface and consist mostly of rounded basalt cobbles. The control section usually has 60 to 70 percent clay and ranges to 75 percent clay in some pedons.
USE AND VEGETATION: The steeper slopes are used as rangeland. The more gently sloping soils are used for dry land crops. Vegetation is scattered trees, shrubs and grass, mainly western juniper, big sagebrush, rabbitbrush, cheatgrass, medusahead and thistles. In some places there are small patches of bare granular soil.
DISTRIBUTION AND EXTENT: Northeastern California and Idaho, and possibly southeastern Oregon and Nevada. The soils are inextensive.
