Book Synopsis Effects of Fertilization on the Growth and Foliar Nutrition of Immature Douglas-fir in the Interior Cedar-hemlock Zone of British Columbia by : Robert Peter Brockley
Download or read book Effects of Fertilization on the Growth and Foliar Nutrition of Immature Douglas-fir in the Interior Cedar-hemlock Zone of British Columbia written by Robert Peter Brockley and published by University of British Columbia Press. 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 Synopsis Comparative Effects of Urea Fertilizer and Red Alder in a Site III, Coast Douglas-fir Plantation in the Washington Cascade Range by :
Download or read book Comparative Effects of Urea Fertilizer and Red Alder in a Site III, Coast Douglas-fir Plantation in the Washington Cascade Range written by and published by . This book was released on 2005 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five randomly assigned treatments were used to quantify effects of adding varying numbers of red alder (Alnus rubra Bong.) or nitrogen (N) fertilization on growth of a 10-year-old conifer plantation at a medium quality site in the western Washington Cascade Range. Zero, 20, 40, and 80 alder trees per acre were retained along with about 300 conifers per acre. Nearly all conifers were coast Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco). A fifth treatment substituted N fertilizer for N-fixing alder. Changes in average tree height, and in numbers of trees, basal area, and volume per acre between plantation ages of 10 and 27 are compared. In pure conifer plots, gross volume growth averaged 26 percent greater on fertilized than nonfertilized plots, indicating measurable benefits of additional N. On both fertilized and nonfertilized plots, an average of 13 percent of the original conifers died. Retaining 20, 40, or 80 alder per acre (7, 13, and 27 percent of the associated conifer trees per acre, respectively) was associated with reduced numbers of Douglas-fir by about 19, 5, and 17 percent, respectively, in the next 17 years. Mortality and growth of Douglas-fir were not related to alder density, but losses of Douglas-fir were especially large on plots where relatively large red alder (20 per acre) were retained. Neither total stand nor conifer yields were changed by retaining alder. Additional comparisons are needed at other locations, especially those with known N deficiency.
