Download or read book Growth and Nutrient Status of Black Spruce Seedlings as Affected by Water Table Depth written by Miroslaw M. Czapowskyj and published by . This book was released on 1986 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2A greenhouse experiment was conducted to study the effects of soil water level on growth, biomass accretion, and inorganic element uptake by black spruce. One-year-old containerized seedlings were grown for 3 years at three water table depths. All trees survived for the duration of the study confirming that black spruce has a certain degree of survival tolerance to high water tables. However, tree height, diameter growth, and biomass production significantly increased as the depth to water table increased. The foliar levels of N, P, K, Mg, Fe, Zn, and B increased and those of Cu and Mn decreased with the increasing depth to the water table. For ash and Ca, differences were significant but did not follow a consistent trend. In shoots, the level of N, Ca, and Mg increased and those of ash, K, Fe, Cu, B, Al, and Mn decreased with the increasing depth to the water table. The level of P was not affected by the water table. In roots, the level of N and Ca increased and the level of ash, Mn, Fe, Al, and Cu decreased with increasing depth to the water table. The level of P, Mg, and Zn was significantly different but did not follow any trend. Foliar concentration of ash, Ca, Na, Mn, Fe, Zn, Cu, Al, and B increased and concentration of N, P, K, and Mg decreased with the increasing foliage age. In shoots, ash, Ca, Al, Fe, and Zn increased and N, P, K, Mg, and B decreased with the increasing tree and shoot age. In roots, Fe, Mn, Na, and Al increased and N, P, and Cu decreased with the increasing tree age.S3.

Download or read book Response of Containerized Black Spruce and Jack Pine Seedlings to Fertilization Rate and Growing Medium written by Stephen John Colombo and published by Maple : Ontario Tree Improvement and Forest Biomass Institute. This book was released on 1988 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the presence of handbooks for the production of containerized tree seedlings, the determination of appropriate rates of fertilization remains an inexact science, since the rate and timing of fertilization can be affected by factors such as local variation in water chemistry, growing media, and the environment in each greenhouse. This report presents the results of semi-operational trial of fertilizer rates and growing media to assess for black spruce and jack pine container seedlings; the range of fertilizer concentrations and seedling nutrient contents resulting in best seedling growth; and the effect of fertilization on bud development and fall freezing damage. Black spruce and jack pine seedlings were grown at the Swastika Tree Nursery according to operational greenhouse practices, at 0, 1/3, 1, 3 or 9X the operational fertilization rates for each species in three growing media.
