Abstract

Abstract

Soil classification in Canada has developed on the concepts of great soil groups and soil series. The present system, officially adopted in 1960 by the soil survey organizations in this country, introduced the two categories of family and subgroup between the series and great groups and the category of order for combinations of great groups. Though based on soil profile features it has a strong genetic bias, expressed through selection of the differentiating criteria. The Canadian system and the Seventh Approximation are analogous at the series and family categories but differ markedly in the subgroup, great group, and order categories. Differences at these higher classification levels are due to differences in the selection of differentiating criteria, to the more restricted scope of the Canadian system, and to its lack of a suborder. The distinctly different nomenclature accents these differences.
