Book The Productivity and Sustainability of Southern Forest Ecosystems in a Changing Environment

Download or read book The Productivity and Sustainability of Southern Forest Ecosystems in a Changing Environment written by Robert Mickler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 892 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research presented here provides a sound scientific basis for management and policy decisions regarding the productivity and sustainability of forest ecosystems in the context of a rapidly changing global environment. It is the synthesis of 5 years of field and laboratory research on southern forests conducted by the US Department of Agriculture Forest Service to provide scientific assessments to the US Global Change Research Program, and, as such, is invaluable for policy makers and land use managers.

Book Belowground Carbon Storage and Soil Organic Matter Quality Following Fertilizer and Herbicide Applications in Ponderosa Pine Plantations Along a Site quality Gradient in Northern California

Download or read book Belowground Carbon Storage and Soil Organic Matter Quality Following Fertilizer and Herbicide Applications in Ponderosa Pine Plantations Along a Site quality Gradient in Northern California written by Karis J. McFarlane and published by . This book was released on 2008 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Belowground carbon (C) storage and quality of soil organic matter (SOM) in forest soils have implications for sustainable forest management and C sequestration, but how these pools change in response to management is poorly understood. I investigated whether fertilization and competing vegetation control, applied alone or in combination early in stand development, affected forest-floor, fine-root, and mineral-soil C and nitrogen (N) pools to 1-m depth at three ponderosa pine (Pinus ponderosa) plantations across a site-quality gradient in northern California. Secondly, I assessed how these treatments affected surface SOM quality at these sites via 1) density fractionation, 2) dissolved organic C (DOC) and dissolved N release during 225-day laboratory incubation, and 3) CO2 evolution and DOC mobilization during 16-day laboratory incubation. Twenty years after plantation establishment, mean belowground C pools, were 83, 177, and 206 Mg C ha-1 for the low-, intermediate-, and high-quality sites, respectively. Belowground N pools for the three sites were 5.6, 7.4, and 6.8 Mg N ha-1, respectively. Responses of aboveground biomass to treatment were marked, but changes in belowground C and N pools to fertilization and competing vegetation control were limited. Fertilization increased total C and N pools at the low- and intermediate-quality sites and increased the proportion of total belowground C and N in the forest floor at all three sites. Competing vegetation control increased the forestfloor C pool at the lowest quality site, but had no effect on total pools. Fertilizer increased whole-soil and light-density-fraction N and decreased C:N ratios at two sites, suggesting increased SOM quality. Fertilization decreased C mineralization at the most productive site, had the opposite effect at the intermediate site, and had no effect at the poor site. Competing vegetation control affected light-fraction C and N concentrations and C:N ratios inconsistently among sites and decreased N mineralization at the most productive site, suggesting decreased SOM quality. Although forest floors were the most sensitive of the belowground C pools to these silvicultural treatments, results suggest that the major mechanism for increased C sequestration through management of these ponderosa pine forests will be through increased tree growth, rather than belowground C storage.

Book The Forests Handbook Volume 2

Download or read book The Forests Handbook Volume 2 written by Julian Evans and published by John Wiley & Sons. This book was released on 2001-03-05 with total page 405 pages. 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.

Book Nutrient Uptake and Cycling in Forest Ecosystems

Download or read book Nutrient Uptake and Cycling in Forest Ecosystems written by L.O. Nilsson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the research results and discussions presented in this book it becomes clear that a profound understanding of the various interrelationships of the nutritional aspects allows the implementation of specific management strategies to improve stability and productivity of forest ecosystems. In particular the effects of environmental changes as related to the impacts of air pollution, global change and land use on nutrient uptake and cycling processes in forest ecosystems are dealt with in detail. The book is divided into six main issues and each topic contains reviews as well as selected results of recent studies.

Book Conifer Seedling Mineral Nutrition

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.

Book Forest Regeneration Manual

Download or read book Forest Regeneration Manual written by Mary L. Duryea and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Forest Regeneration Manual presents state-of-the-art information about current regeneration practices for southern pines in the United States.
