The Carbon Budget Model of the Canadian forest sector required initial estimates of carbon content in soils for each of the ecoclimatic regions of Canada. An analytical data base of soil profile and horizon characteristics was compiled from published and unpublished soil survey reports, inventories, and research data from companies, governments, and universities to represent the common forest and tundra mineral soil conditions across Canada. The data base was arranged to facilitate data handling and analysis to examine the role of different parameters in the carbon dynamics of Canadian soils. Each soil profile has location, horizon development, carbon content, site, and vegetation information as well as analyses of other chemical and physical soil parameters expressed in common units. Initialization values from this data base have resulted in the Carbon Budget Model significantly reducing its modeled soil carbon pool sizes; however, no major changes to the overall C balance for Canadian forests and forest activities were found compared to the earlier Phase I model runs. The data base provides an improved representation of the carbon content in soils of Canada.
