Soil morphology, site descriptions, and physical and chemical data for 130 soil profiles from the AOSERP study area are presented in this section. Except for some miscellaneous land units, each of the soil groups are represented by at least one profile description. For many of the soil groups, several profile descriptions are given. A list or index of the profiles described has not been provided, but a search for data about a specific soil group is facilitated by the alphabetical arrangement of soil groups. The soil descriptions consist of three parts - a general site description, the profile description, and analytical data for the profile.
