- Poster Paper: Foliar Potassium Status Explains Douglas-fir Response to Nitrogen Fertilization in the Inland Norwest, USA
- Creator:

- Date Created (ISO Standard):
- 1991
- Description:
- Despite apparently inadequate N levels throughout the Inland Northwest of the United States, trees on some sites showed no increased growth 8 yr after N fertilization. Nor did higher N application rates consistently produce higher response. These facts indicated that other factors are limiting tree growth at these sites. Results suggest that K status is one important factor, influencing N fertilization response in the following general ways: (I) for stands with low pretreatment foliar K levels, the amount and duration of growth response are reduced, and higher N fertilizer rates produce less response; and (2) for all stands, growth response declines when foliar K decreases after N fertilization.
