Classification, Properties, and Management of Aridisols

This presentation has been converted from a slide, tape, and booklet presentation by C.B. Mack and O.A. Chadwick, published in 1987 by the Office of Arid Lands Studies. The original was based on the 1975 edition of Soil Taxonomy, and while we have tried to be faithful to the original, Soil Taxonomy has recently been updated, and many parts of it were changed. Since many soils have been classified using the old system and many soil scientists trained on it, Joe Tabor has made some changes and additions to the original text to bridge the old to the new by explaining how the soils shown in the slides are classified in both systems. Please forgive any confusion this has caused, but we would like have the information here be as useful as possible.
