This book was released on 2006 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The effects of fertilization with nitrogen (N) alone, and in combination with sulphur (S), on the growth and foliar nutrition of six immature, managed Douglas-fir (Pseudotsuga menziesii var. glauca [Beissn.] Franco) stands in the Interior Cedar-Hemlock (ICH) biogeoclimatic zone of British Columbia are reported 6 years after treatment. Results indicate that interior Douglas-fir stands growing on circummesic sites within the ICH zone are generally responsive to fertilization. Disregarding results from one installation that was damaged by Armillaria root disease, average net volume response following fertilization with N alone was 13.5 m3/ha (range: 6.5-24 m3/ha) compared to the control treatment. Six-year volume gains from N+S additions averaged 16 m3/ha (range: 10-23 m3/ha). In relative terms, stand volume responses to fertilization with N and N+S averaged 24% (range: 8-41%) and 28% (range: 16-39%), respectively. Growth projections generated by the tipsy growth and yield program indicate that the accelerated stand development following a single fertilizer application will likely reduce biological rotations (i.e., culmination of mean annual increment) and technical rotations (e.g., minimum harvestable age) by 2-3 years. Relative growth responses compare favourably with results from Douglas-fir fertilization studies in other jurisdictions.??Pre- and post-fertilization foliar nutrient analyses indicate that several of the sites were marginally S deficient, and that S status deteriorated 1 year following N fertilization. Added S was readily taken up, thereby maintaining a favourable N:S balance in trees fertilized with N+S. Despite improvements in foliar S status, the incremental growth benefits of added S may be too small on most sites to justify the extra expense involved in blending and applying N+S fertilizers in large-scale aerial operations.??Results from this study, and others, indicate that pre-fertilization levels of foliar N and sulphate S (SO4) may have utility in selecting candidate stands and in making appropriate fertilizer prescriptions. For example, the largest growth responses following fertilization may be expected in stands with pre-fertilization foliar N levels less than 11.5 g/kg ( 13 g/kg when using dry combustion analytical methods). Also, low foliar N combined with small amounts of pre-fertilization foliar SO4 (

Book excerpt: The British Columbia Forest Service (BCFS) and the Canadian Forest Service (CFS) have a long history of collaboration across a wide range of functions and topics. This includes research, technology transfer and extension, co-management and delivery of federal-provincial agreements, and partnering on national and international initiatives. As the BCFS approaches its centennial, it is interesting to examine the achievements that have come from this 100-year relationship. The nature of the various projects and initiatives undertaken over the years reflects the evolving nature of forest management, and the relative strengths of the CFS and BCFS have contributed to successful outcomes in many collaborative initiatives. Looking forward, we believe a continuation of CFS-BCFS partnering will benefit both institutions, and will help ensure management of BC's forests continues to balance the multiple needs of current and future generations.
