Effect of Organic Amendments on Douglas-Fir Transplants Grown in Fumigated Versus Non-Fumigated Soil

Khadduri, N. IN: National Proceeding: Forest and Conservation Nursery Associations - 2009. USDA Forest Service, Rocky Mountain Research Sta­tion, Proceedings RMRS-P-62, p. 46-50. 2010.

We transplanted one-year old Douglas-fir (Pseudotsuga menziesii var. menziesii) seedlings into compost-amended soil that had either been spring-fumigated with a methyl bromide/chloropicrin combination or left unfumigated. Seedling nutrient, pathology, morphology, and packout measurements were significantly better for those transplanted into fumigated rather than non-fumigated soil, regardless of compost treatment. Among seedlings transplanted into non-fumigated soil, those grown in the biosolid and bark-based composts had the highest average number of packable seedlings.
