Microbial analysis of coniferous forest and nursery soils : effects of ectomycorrhizae, volatiles, and humic-rich organic substrates

Creator:

Schisler, David Albert

Abstract:

Fusarium spp. frequent conifer nursery soils yet are rarely recovered from coniferous forest soils. Experiments were performed to determine what influence humic-rich organic amendments and volatiles from soil, ectomycorrhizal fungi and ectomycorrhizae have on the populations of several physiologic and taxonomic microbial groups potentially related to this phenomenon. A comparative...

Ammonia-oxidizer and denitrifier populations in boreal forest soils of differing nitrogen availability

Creator:

Burton, Marci S.

Abstract:

Nitrification and denitrification are major biological processes transforming nitrogen (N) in soils to plant available N, highly leachable nitrate (NO₃⁻) and gaseous N oxides. Although many studies in the past have studied N cycling communities, the effect of increased N inputs on ammonia-oxidizer and denitrifier population dynamics is still under...
