Download or read book Soil Quality for Crop Production and Ecosystem Health written by E.G. Gregorich and published by Elsevier. This book was released on 1997-11-10 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is a complex body that exists as many types, each with diverse properties that may vary widely across time and space as a function of many factors. This complexity makes the evaluation of soil quality much more challenging than that of water or air quality. Evaluation of soil quality now considers environmental implications as well as economic productivity, seeking to be more holistic in its approach.Thus, soil quality research draws from a wide range of disciplines, blending the approaches of biologists, physicists, chemists, ecologists, economists and agronomists, among others.This book presents a broad perspective of soil quality that includes these various perspectives and gives a strong theoretical basis for the assessment of soil quality.A short glossary provides definitions for terms used throughout the book.
Download or read book Textile Composites and Inflatable Structures written by Eugenio Oñate and published by Springer Science & Business Media. This book was released on 2006-03-30 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book collects state-of-the-art research and technology for design, analysis, construction and maintenance of textile and inflatable structures. Textile composites and inflatable structures have become increasingly popular for a variety of applications in OCo among many other fieldsaOCo civil engineering, architecture and aerospace engineering. Typical examples include membrane roofs and covers, sails, inflatable buildings and pavilions, airships, inflatable furniture, airspace structures etc. The book contains 18 invited contributions written by distinguished authors who participated in the International Conference on Textile Composites and Inflated Structures held in Barcelona from June 30th to July 2nd, 2003. The meeting was one of the Thematic Conferences of the European Community on Computational Methods in Applied Sciences (ECCOMAS). The different chapters discuss recent progress and future research directions in membrane and inflatable structures built with new textile composite materials. Approximately half of the book focuses on describing innovative numerical methods for structural analysis of such structures, such as new nonlinear membrane and shell finite elements. The rest of the chapters present advances in design, construction and maintenance procedures."

Download or read book Wetland Indicators written by Ralph W. Tiner and published by CRC Press. This book was released on 1999-04-21 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understand the current concept of wetland and methods for identifying, describing, classifying, and delineating wetlands in the United States with Wetland Indicators - capturing the current state of science's role in wetland recognition and mapping. Environmental scientists and others involved with wetland regulations can strengthen their knowledge about wetlands, and the use of various indicators, to support their decisions on difficult wetland determinations. Professor Tiner primarily focuses on plants, soils, and other signs of wetland hydrology in the soil, or on the surface of wetlands in his discussion of Wetland Indicators. Practicing - and aspiring - wetland delineators alike will appreciate Wetland Indicators' critical insight into the development and significance of hydrophytic vegetation, hydric soils, and other factors. Features Shows 55 color plates, documenting wetland indicators throughout the nation - with more than 34 soil plates and aerial photos Illustrates other wetland properties with more than 50 figures Provides over 60 tables, including extensive tables of U.S. wetland plant communities and examples for determining hydrophytic vegetation Contents Wetland Definitions Wetland Concepts for Identification and Delineation Plant Indicators of Wetlands and Their Characteristics Vegetation Sampling and Analysis for Wetlands Soil Indicators of Wetlands Wetland Identification and Boundary Delineation Methods Problem Wetlands and Field Situations for Delineation Wetland Classification Wetlands of the United States: An Introduction, With Emphasis on Their Plant Communities Wetland Mapping and Photointerpretation
Download or read book Handbook of Ecological Restoration written by Martin R. Perrow and published by Cambridge University Press. This book was released on 2002-09-05 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume handbook is a comprehensive account of the rapidly emerging and vibrant science of the ecological restoration of habitats and species. Ecological restoration aims to achieve complete structural, functional, self-maintaining biological integrity following disturbance. In practice, any theoretical model is modified by a number of economic, social, and ecological constraints. Consequently, material that might be considered as rehabilitation, enhancement, re-construction, or re-creation is also included. Principles of Restoration defines the underlying principles of restoration ecology in relation to manipulations and management of the biological, geophysical, and chemical framework.

Download or read book Free Spaces written by Sara Margaret Evans and published by HarperCollins Publishers. This book was released on 1986 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: What are the environments, the public spaces, in which ordinary people become participants in the complex, ambiguous, engaging conversation about democracy: participators in governance rather than spectators or complainers, victims or accomplices? What are the roots, not simply of movements against oppression, but also of those democratic social movements which both enlarge the opportunities for participation and enhance people's ability to participate in the public world? In Free Spaces, Sara M. Evans and Harry C. Boyte argue for a new understanding of the foundations for democratic politics by analyzing the settings in which people learn to participate in democracy. In their new Introduction, the authors link the concept of free spaces to recent theoretical discussions about community, public life, civil society, and social movements.
Download or read book Nutrient Cycling in Forest Ecosystems written by Robert G. Qualls and published by . This book was released on 2020 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The long-term productivity of forest ecosystems depends on the cycling of nutrients. The effect of carbon dioxide fertilization on forest productivity may ultimately be limited by the rate of nutrient cycling. Contemporary and future disturbances such as climatic warming, N-deposition, deforestation, short rotation sylviculture, fire (both wild and controlled), and the invasion of exotic species all place strains on the integrity of ecosystem nutrient cycling. Global differences in climate, soils, and species make it difficult to extrapolate even a single important study worldwide. Despite advances in the understanding of nutrient cycling and carbon production in forests, many questions remain. The chapters in this volume reflect many contemporary research priorities. The thirteen studies in this volume are arranged in the following subject groups: • N and P resorption from foliage worldwide, along chronosequences and along elevation gradients; • Litter production and decomposition; • N and P stoichiometry as affected by N deposition, geographic gradients, species changes, and ecosystem restoration; • Effects of N and P addition on understory biomass, litter, and soil; • Effects of burning on soil nutrients; • Effects of N addition on soil fauna.
