Description
This is the reference or diagnostic community for the site. The description is based on early range site descriptions, clipping data, professional consensus of experienced range specialists, and analysis of field work.

Description
This is an alternative state from the reference. Hydrologic and ecological functions have been altered. The site is in current crop production or has been tilled and seeded to an introduced forage. The hydrology has been altered and requires different management. See Soil Survey or Extension publications for yield data.
Submodel
Description
This is an alternative state from the reference. Hydrologic and ecological functions have been altered. This state is the result of water erosion over bare soil. Most of the "A" horizon of the soil profile has been displaced. The remaining subsoil is very low in fertility. Some native grasses and forbs will persist in this state, however, production is greatly reduced.
Submodel
Mechanism
Through tillage and seeding this site will transition to state 2.
