Implication

This research finds that soil fumigation and cropping history enhance ectomycorrhizae in Douglas-fir seedlings, indicating soil management's importance.

Key Points

Seedlings in soil fumigated with Vorlex had more ectomycorrhizae than controls in nonfumigated soil.
Fertilization with urea reduced tomentose mycorrhizae compared to nonfertilized soil or superphosphate-fertilized soil.
Inoculation with mycorrhizal roots increased mycorrhizae counts but not seedling weight over controls.
Soil from Douglas-fir monoculture improved root growth and mycorrhizae formation compared to soils from agricultural crops.
