Download or read book Conifer Seedling Mineral Nutrition written by R. van den Driessche and published by CRC Press. This book was released on 1990-12-13 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conifer Seedling Mineral Nutrition provides a comprehensive review of conifer seedling mineral nutrition and its significance to forestry. The book covers relationships between mineral supply and uptake; the effects of nutrition on seedling growth; an integration of the ideas of T. Ingestad with classical growth analysis concepts; practical aspects of assessing nutrient status and details of fertilizing bare root and container nursery stock; and fertilizing vegetative propagules. The book also describes and illustrates Mycorrhizas, assessing their importance to plantation establishment in an analysis of recent papers reporting field trials. The effects of nutrients on stress resistance and establishment when applied in the nursery and while planting are discussed in the final chapter. It will prove useful to reforestation research workers, nurserymen, and silviculturalists and should be considered essential reading for forestry students.

This book was released on 2003 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil physical, chemical, and biological components as well as climate and physiographic characteristics can interact to have a great effect on forest regeneration and seedling growth response to different establishment activities. The objective of this project was to increase the understanding of the interactions between soil type, controlled-release fertilizers, and soil water content on Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] seedlings. Douglas-fir seedlings were sown in late February 2001 and transplanted into pots at OSU in mid-May. Two forest soil types (Jory and Apt) were mixed with five different controlled-release fertilizer (CRF) treatments (Customblen®, Wilgro®, Osmocote®, and two Apex®), and one control unfertilized treatment. Three moisture regimes were randomly assigned to each of the soil/fertilizer treatments (12, 18 and 24% soil water content based on soil dry weight). The same volume of soil was put into each pot. The same weight for each soil (2700 g of Jory and 2300 g of Apt) was used based on volume. The study design was a factorial completely randomized block design with five replications. Seedlings differed greatly by fertilizer treatment, soil type, and moisture regime in many of their morphological and nutritional characteristics. Seedlings grown in the wettest moisture treatment were larger than those grown in the drier treatments, and had the greatest nutrient concentrations and contents. Unfertilized control seedlings were larger in the Apt soil than in the Jory soil. These differences were also apparent with the application of fertilizers. Among the fertilizers, Wilgro® tended to have the greatest effect on seedlings, especially under the wettest moisture regime. Vector analysis showed that for some nutrients, Apex® (Amn), Apex® (Nit), and Osmocote Plus® had antagonistic or toxic effects. For these fertilizers, a higher P concentration remaining in the prills, correspond to the lower soil total and available P concentration. FESEM pictures suggested that a large proportion of nutrients were still inside the prills. Wilgro® and Customblen® were mostly dissolved at the time of sampling, and corresponded to greater total and available soil Phosphorus with these two fertilizers. The use of CRF in the Pacific Northwest offers potential to optimize resources and meet seedling nutritional requirements. The study results suggest that CRF application must consider soil moisture availability with more conservative applications on dry sites.

Available in PDF, EPUB and Kindle. Book excerpt: The future of the world's forests is at the forefront of environmental debate. Rising concerns over the effects of deforestation and climate change are highlighting the need both to conserve and manage existing forests and woodland through sustainable forestry practices. The Forests Handbook, written by an international team of both scientists and practitioners, presents an integrated approach to forests and forestry, applying our present understanding of forest science to management practices, as a basis for achieving sustainability. Volume One presents an overview of the world's forests; their locations and what they are like, the science of how they operate as complex ecosystems and how they interact with their environment. Volume Two applies this science to reality; it focuses on forestry interventions and their impact, the principles governing how to protect forests and on how we can better harness the enormous benefits forests offer. Case studies are drawn from several different countries and are used to illustrate the key points. Development specialists, forest managers and those involved with land and land-use will find this handbook a valuable and comprehensive overview of forest science and forestry practice. Researchers and students of forestry, biology, ecology and geography will find it equally accessible and useful.
