Seven-year response of year-old Douglas-fir to nitrogen fertilizer / View Metadata By: Miller, Richard E. - Pienaar, Leon V. (Leon Visser), - Pacific Northwest . Progress 10/01/08 to 09/30/09 Outputs OUTPUTS: A series of Douglas-fir test sites were established this past year to test the idea of moving seed sources in response to climate change and evaluate options for adapting to climate change through assisted migration, using silvicultural and genetic options. In the past years, the Pacific Northwest Research Station has established. Miller RE, Pienaar LV () Seven-year response of 35 year-old Douglas-fir to nitrogen fertilizer.

H. BrixEffects of nitrogen fertilizer source and application rates on foliar nitrogen concentration, photosynthesis and growth of Douglas-fir Can. J. For. Res., 11 (), pp. Google Scholar. Busse et al. () and Shan et al. () both reported a reduction in soil carbon resulting from vegetation control in plantations of year-old P. ponderosa and year-old Pinus elliottii. The nitrogen saturation hypothesis (Aber et al. , ) predicts that the final stages of N saturation lead to tree decline and even death. Some studies indeed report decreased growth in response to high N-loads (e.g. Magill et al. , ). Red alder is also a nitrogen-fixing species, so over a to year rotation, the root disease will be minimized and the site will have additional nitrogen for the next crop of Douglas-fir. He could wait to site prep and plant the brush field.
