Lodgepole Pine Nutrition And Fertilization

Summarizes results obtained from 33 lodgepole pine fertilization research installations established at the Kalamalka Forestry Centre in Vernon, British Columbia. Most of the research was conducted in 15- to 35-year-old thinned, fire-origin stands in the montane spruce and sub-boreal spruce biogeoclimatic zones. Results are discussed with regard to such research topics as: pre- and post-fertilization foliar nutrient status; response to nitrogen additions; effects of nitrogen application rate; effects of post-thinning stand density and site index; effects of timing of fertilization and thinning; small-mammal damage; and effects of snow accumulation.
