Description:
Document outlining the plan for the IFTNC for the next 5 years, it includes a goal statement and an experiment with the following Preface: Previous results from IFTNC Douglas-fir and ponderosa pine experiments suggest a link between nutrition, particularly potassium nutrition, and insect and disease pests. Mortality rates in the Douglas-fir trials were significantly higher instands with poor pre-treatment foliar K status after application of 400 lbs. of N/ Ac. lnterestingly, the most common mortality causes in this K status/ treatment category were root rots and bark beetles. Results from the Montana ponderosa pine experiment showed that N only treated plots experienced higher mortality rates, producing a net loss in volume growth after 4 years. Conversely, N + K treated plots showed less mortality than control plots. The net volume growth effect associated with adding K was highly significant. Mortality on the N only plots was six times as great as control plot mortality; over 80% of it resulting from bark beetle activity N+ K plots showed less mortality than control plots with no bark beetle mortality.
