At lower levels in the systems, differences become progressively greater. The tables have been revised from those prepared by J.S. Clayton for previous editions of the Canadian System of Soil Classification. Revisions were required because of some changes in horizon designations and in the definitions of horizons and taxa in both the Canadian and U.S. systems. Correlation at the subgroup level is not presented. The tables are not adequate for correlating either the horizon designations or the taxonomy of a given pedon as expressed in one system with those of another system.
Adequate correlation requires knowing the criteria and definitions in the systems involved.
