A question in soil order
From Course talk:APBI403
Gleysol is soil order (ie the broadest, most general soil classification category), while Orthic Humic Gleysol is the sub-group in Canadian soil classification system.
Classification categories in the Canadian system are (from the most general to the least general): order, great group, sub-group, family, and series.
For example, samples #1 and 6 belong to Gleysolic order, Humic Gleysol great group, Orthic Humic Gleysol sub-group and Delta soil series. Family is typically not specified since it is related to parent material and that info is typically provided in descriptive terms.
