The action and interaction of soil-forming processes as influenced by soil-forming factors gives rise to distinct soil horizons. These layers are assigned distinctive alphabetic symbols as a form of shorthand for their characteristics.

The landscape of this profile extends from Newfoundland on the east coast of Canada, to the majority of Ontario and Manitoba, to northern portions of Saskatchewan and Alberta, to much of the Northwest Territories and Nunavut. 1. In the past, the Canadian interior was covered with massive glaciers. About 15,000 years ago these glaciers receded north...
This profile covers all of British Columbia and the Yukon as well as parts of the Northwest territories and the maritime provinces (excluding Newfoundland). Also known as the Cordilleran and Appalachian Orogens. 1. The Earth beneath our feet is not stationary; in fact, quite the opposite. Huge continental and oceanic plates are constantly moving ac...
The soil profile for the prairies or the Interior Platform, covers the majority of Alberta, Saskatchewan, Manitoba as well as parts of the Northwest Territories, Nunavut, Ontario, Quebec, and Newfo...
Our intent for the field guide is two-‐fold: 1) to simplify the use of the Canadian System of Soil Classification in the field and 2) to allow field testing of a new soil order for Anthroposolic soils, which has been proposed for inclusion in the Canadian System of Soil Classification.

The horizon and layer designations L, F, H, R, and W may be used alone, and the horizon designation C may be used alone except when the material is affected by reducing conditions (Cg), cementation (Cc), salinity (Cs or Csa), CaCO 3, (Ck or Cca), or permafrost (Cz).
Vertic horizon: A horizon affected by argillipedoturbation, which is the disruption and mixing of the horizon caused by shrinking and swelling of the clayey soil mass. It is characterized by the following: 1) irregular shaped, randomly oriented, intrusions of displaced materials within the solum.
A list of the designations and some of the properties of soil horizons and layers foilows. More detailed definitions of some horizons and layers may be found in The Canadian System of Soil Classification
