Effects of repeated fertilization in a young spruce stand in central British Columbia

Autor: R. P. Brockley

Publikováno v: Canadian Journal of Forest Research. 40:1687-1697

Sustained growth responses and large reductions in rotation length can be achieved by repeatedly fertilizing young boreal forests. This paper reports the effects of different regimes and frequencies of fertilization on the foliar nutrition and growth

Growth response of young lodgepole pine to thinning and repeated fertilization treatments: 10-year results

Autor: Druscilla S. Sullivan, R. P. Brockley, R. Winter, Pontus M.F. Lindgren, Thomas P. Sullivan

Publikováno v: Forestry. 80:587-611

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

Soil and lodgepole pine foliar responses to two fertilizer sulphur forms in the Sub-Boreal Spruce zone, central interior British Columbia

Autor: R P Brockley, P T Sanborn, J Prietzel

Publikováno v: Canadian Journal of Forest Research. 35:2316-2322

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

Effects of post-thinning density and repeated fertilization on the growth and development of young lodgepole pine

Autor: R P Brockley

Publikováno v: Canadian Journal of Forest Research. 35:1952-1964

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

Effects of different sources and rates of sulphur on the growth and foliar nutrition of nitrogen-fertilized lodgepole pine

Autor: R P Brockley

Publikováno v: Canadian Journal of Forest Research. 34:728-743

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
