Two Year Basal Area Response to N and K Fertilization for Mixed Conifer Stands in North Central Washington Item Info

Two years after fertilization, overall gross basal area response was 31.1% on those plots receiving the 200 lb. nitrogen (N) acre and 33.8% on those plots receiving 200 lb. nitrogen plus 200 lb. potassium (K) acre. Results from this study show that response was different by species, with lodgepole pine expressing higher absolute and relative response than ponderosa pine, western larch or mixed conifer for both treatments. Sites that were predominately ponderosa pine expressed low growth but did show good relative (percent) response to the treatments. Western larch and mixed species sites expressed good absolute response. Gross Basal area response was similar to foliar nutrient and needle weight response. The addition of potassium to the fertilizer mix did not significantly affect two year basal area growth or response.
