Abstract

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.
