摘要

This publication, Keys to Soil Taxonomy, serves two purposes. It provides thetaxonomic keys necessary for the classification of soils according to Soil Taxonomy in a form that can be used easily in the field, and it also acquaints users of Soil Taxonomy with recent changes in the classification system. This volume includes all revisions of the keys that have so far been approved, replacing the original keys in Soil Taxonomy: A Basic System of Soil Classification for Making and Interpreting Soil Surveys (1975), the work on which this abridged version, first published in 1983, is based. This publication incorporates all amendments approved to date and published in National Soil Taxonomy Handbook (NSTH) Issues 1-17.
