A 7-year litterbag experiment examined mass loss dynamics of Sitka alder ( Alnus viridis (Chaix) DC. subsp. sinuata (Regel) A. Löve & D. Löve) and lodgepole pine ( Pinus contorta Dougl. ex Loud. var. latifolia Engelm. ex S. Watson) foliage litter i

The effects of different regimes and frequencies of repeated fertilization (applied periodically and yearly) on the foliar nutrition and growth of young lodgepole pine ( Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) were investigated in cent

Summary This study was designed to test the hypothesis that large-scale pre-commercial thinning (PCT) to various stand densities, at ages 12 – 14 years, combined with repeated fertilization, would, over a 10-year treatment period, enhance productiv

Sulphur (S) fractions, total nitrogen (N) concentrations, and cumulative net S mineralization of forest floors and surface mineral soils (0-20 cm) were measured 13 years after an S-deficient lodgepole pine (Pinus contorta var. latifolia Engelm.) stan

The effects of factorial combinations of post-thinning density and fertilization on the growth and development of young lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) were investigated in central British Columbia. The effects

The effects of nitrogen (N) fertilizer, alone and in combination with different sources and rates of sulphur (S), on foliar nutrients and tree growth are reported over 3 and 6 years, respectively. After 3 years, foliar S levels in the N+S treatments

The 9-year effects of nitrogen (N) and boron (B) fertilization on the growth and foliar B nutrition of lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) were evaluated in two different ecosystems in the interior of British Columb

Annual N2-fixation by Sitka alder (Alnus viridis (Chaix) DC. ssp. sinuata (Regel) A.&D. Love) was estimated at 10–15 kg N ha−1 over three growing seasons in a young lodgepole pine (Pinus contorta Dougl. ex Loud.) stand in the Sub-Boreal Spruce bi
