  • Modeling nitrogen fixation in dead wood

    Creator:
    Hicks, William Thomas
    Abstract:
    A mechanistic simulation model of nitrogen fixation in dead wood was developed to help synthesize knowledge, develop hypotheses, and estimate rates of nitrogen fixation in the Pacific Northwest. In this model nitrogen fixation is directly controlled by log substrate, temperature, moisture, and oxygen content. Respiration and diffusion of oxygen indirectly...

  • Influences of nitrogen on carbon dynamics in forest soil and density fractions

    Creator:
    Swanston, Christopher W.
    Abstract:
    Application of N fertilizer is a common forest management practice in the Pacific Northwest, yet the long-term influence of fertilization on forest soil properties is not well known. Although elevated N often increases mineralization of C and N from labile organic matter, negative effects have been documented in recalcitrant organic...
