Abstract Although widely separated geographically and formed on diverse parent materials, nine of the ten dominant soils on the biome sites are classified in the Mollisol order. This order is comprised mainly of the dark, base rich soils of the semiarid and subhumid steppes. Even though they are consistent as to order, the soil properties vary widely. Texture varies from silty clay to loamy sand. Depth to bedrock varies from 35 to greater than 150 cm, and estimated available moisture storage capacity to 100 cm depth varies from 4.5 to 20 cm. While a few are acidic in the surface, with the exception of the mountain grassland, the soils tend to be largely base saturated. Native vegetation could be expected to respond to nitrogen fertilizer during periods when moisture availability is not limiting growth. Phosphorus responses might be expected at some sites. It is unlikely that native vegetation will respond to additions of other nutrients on these soils.
