  • Interactions between ecosystem nitrogen and bedrock control long-term calcium sources in Oregon Coast Range forests

    Creator:
    Hynicka, Justin D.
    Abstract:
    Ecosystem nitrogen (N) supply strongly influences the availability and cycling of other essential nutrients in temperate forests, especially calcium (Ca). Short-term additions of N that exceed ecosystem demands often increase dissolved nitrate fluxes and decrease soil pH, which can stimulate soil Ca loss. However, the long-term effects of high N...

  • An Analysis of Nutrient Depletion in Douglas-fir Forests of the Oregon Coast Range

    Siah, Kaveh G.
    Abstract:
    Nutrient limitation constrains tree growth in many managed forests. Nitrogen (N) is the most common limiting nutrient, but high N supply can shift limitation to other nutrients, particularly phosphorus (P) and the base cations calcium (Ca), magnesium (Mg), and potassium (K). As different soil minerals have different capacities to supply...
