Evaluation of Three Growing Media Substrates for Western Larch Seedling Production at the USDA Forest Service Coeur d’Alene Nursery

Davis, A. S., Eggleston, K., Pinto, J. R., and Dumroese, R. K. USDA Forest Service, Rocky Mountain Research Station, Pro­ceedings RMRS-P-58. p.37-41. National Proceedings: Forest and Conservation Nursery Association - 2008. 2009.

Most container forest tree seedlings produced in the Inland Northwest of the United States are grown using a Sphagnum peat-based substrate. Given the high cost of peat moss, and environmental concerns regarding its production, amendments are considered a viable way to reduce overall peat consumption. Sawdust, pine bark, and coconut coir can be used as organic amendments, while perlite, sand, and vermiculite are often incorporated as inorganic components of growing media mixes (Landis and others 1990).
