A Basic System of Soil Classification for Making and Interpreting Soil Surveys.
The second edition of Soil Taxonomy: A Basic System of Soil Classification for Making and Interpreting Soil Surveys is the result of the collective experience and contributions of thousands of pedologists from around the world. This new edition includes many improvements. Two new soil orders, Andisols and  elisols, are added. Low-activity clays are defined, and taxa are developed. The Aridisol, Alfisol, Histosol, Inceptisol, Mollisol, Oxisol, Spodosol, and Vertisol orders are updated. Aquic conditions, episaturation, and oxyaquic subgroups are defined. Additions and improvements are made at the family level.
