Association of hydrophobic organic compounds with dissolved soil organic carbon

Creator:

Ochs, Michael

Abstract:

Volatile hydrophobic compounds (HOCs) brought into soil and sediment systems represent a serious threat to the environment. Dissolved organic carbon (DOC) may exert an important influence over the total aqueous solubility and mobility of organic pollutants through their incorporation into micelles or the formation of soluble complexes. To date, however,...

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...

Determinants of microbial community structure and substrate utilization potential in soils of vegetable cropping systems

Creator:

Schutter, Mary E.

Abstract:

The Oregon Long-Term Soil Quality Project was initiated to identify soil properties that respond rapidly to alternative management practices. Such practices included winter cover cropping, which was implemented at two experimental research stations and several grower fields throughout the Willamette Valley. The goal of this thesis was to identify the...
