A Soil Profile and Organic Carbon Data Base for Canadian Forest and Tundra Mineral Soils

In this report, soil information has been assembled from the forest and tundra regions across Canada to serve as a basis for an improved soil carbon component in future carbon budget assessments of the Canadian forest sector. The report describes a soil profile data base that contains soil and environmental data for over 1400 pedons (totalling more than 7000 soil horizons) from mineral soils in the forest and tundra regions of Canada. Information is included on data sources and organization, data base format, and data base variables. This is followed by an example of the application of these data to evaluate the carbon budget of the Canadian forest sector.
