Book Synopsis Soil and Sediment Remediation by : Piet Lens
Download or read book Soil and Sediment Remediation written by Piet Lens and published by IWA Publishing. This book was released on 2005-09-30 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

Book Synopsis Maya Subsistence by : Kent V. Flannery
Download or read book Maya Subsistence written by Kent V. Flannery and published by Academic Press. This book was released on 1982-02-28 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maya Subsistence: Studies in Memory of Dennis E. Puleston presents studies on the history and development of Maya subsistence in honor of Maya archaeologist Dennis E. Puleston (1940-1978). The discussions are organized around four themes: ecological models for early Maya adaptations; archaeological investigations of Pre-classic and classic Maya subsistence; contributions of geography and soil science to an understanding of ancient Maya subsistence; and Maya subsistence in the post-classic, colonial, and modern eras. Comprised of 15 chapters, this book begins with an analysis of Puleston's career and a review of the history of inquiry into Maya subsistence. Maya subsistence from the earliest Pre-classic period up to the present day is then examined, with emphasis on agriculture, hunting, wild plant collecting, animal husbandry, and trade. In particular, cultural development in the Valley of Guatemala from 1500 B.C. to the Spanish Conquest is discussed, along with the resources of the tropical lowlands and actual prehistoric cornfields miraculously preserved by volcanic ashfall in El Salvador. The book also presents evidence for Maya soil and water conservation over the entire area from Yucatan to Chiapas and central Guatemala, and looks at the traditional role of women and animals in lowland Maya economy. This monograph will be of interest to archaeologists and anthropologists.

Book Synopsis Microbiology of Tropical Soils and Plant Productivity by : Y.R. Dommergues
Download or read book Microbiology of Tropical Soils and Plant Productivity written by Y.R. Dommergues and published by Springer Science & Business Media. This book was released on 1982-11-30 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is an established fact that we must continually increase and improve agricultural production if we are to meet even the minimum requirements of a growing popu lation for food, shelter, and fuel. In recent years, the introduction of new plant varieties and the extensive use of fertilizers have effectively increased crop yields, but intensifying agricultural methods has often led to depleting soil fertility. Two examples of the harmful consequences of intensive farming practices are the loss of up to 2.5 cm of topsoil every 15 years in the United States through erosion and the alarming rise in environmental pollution through widespread use of pesticides. Countless other processes affecting the activity of soil micro flora and the inter actions between microorganisms and plants may pose an equal danger to soil equilibrium, but their potential hazards are often overlooked because of an insufficient understanding of soil microbiology on the part of scientists. In the first published study of its kind, the authors of this book have attempted to address major aspects of the microbial activity of soil in the tropics. Tropical conditions serve as an ideal context for a discussion of soil microbiology, since biological processes in the soil are particularly active in tropical environments in comparison to other settings and in relation to physical and chemical processes.
Book Synopsis Agroforestry for Ecosystem Services and Environmental Benefits by : Shibu Jose
Download or read book Agroforestry for Ecosystem Services and Environmental Benefits written by Shibu Jose and published by Springer. This book was released on 2012-03-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry systems are believed to provide a number of ecosystem services; however, until recently evidence in the agroforestry literature supporting these perceived benefits has been lacking. This volume brings together a series of papers from around the globe to address recent findings on the ecosystem services and environmental benefits provided by agroforestry. Specifically, this volume examines four major ecosystem services and environmental benefits: (1) carbon sequestration, (2) biodiversity conservation, (3) soil enrichment and (4) air and water quality. Past and present evidence clearly indicates that agroforestry, as part of a multifunctional working landscape, can be a viable land-use option that, in addition to alleviating poverty, offers a number of ecosystem services and environmental benefits. This realization should help promote agroforestry and its role as an integral part of a multifunctional working landscape the world over. The book should be particularly useful to students, professionals, researchers and policy makers involved in natural resource management, agroforestry, biodiversity conservation, and environmental management.

Available in PDF, EPUB and Kindle. Book excerpt: El progresivo aumento de la población lleva consigo un incremento de la superficie cultivada que dé lugar a un incremento de la producción agrícola de alimentos capaz de cubrir las necesidades cada vez mayores de la población mundial. Ello implica que el suelo, la superficie cultivada, se encuentre en las mejores condiciones para proporcionar a los cultivos todo aquello que necesiten en las mejores condiciones físicas, químicas y biológicas. La obra que se presenta consta de diez temas. Los dos primeros nos recuerdan los conceptos fundamentales del suelo y de la nutrición vegetal, que nos permiten establecer correctamente la acción de los fertilizantes que a continuación se describen. El apartado de los fertilizantes propiamente dichos se inicia con un tema general, en el que se define el fertilizante, sus diversos orígenes, tipos y presentaciones, así como se describen algunas de las propiedades de estos compuestos y su influencia en los suelos. Tres temas se dedican a los fertilizantes nitrogenados, fosfóricos y potásicos, como suministradores de los tres principales macronutrientes vegetales. En ellos, junto a los productos de síntesis, se presta atención al uso de materiales naturales como aporte de estos elementos. El siguiente tema, el siete, nos aporta el conocimiento de aquellos productos que completan el suministro del resto de los nutrientes esenciales para las plantas: los macronutrientes secundarios y los micronutrientes, con especial atención a los quelatos y su acción. El estudio de materiales orgánicos, de origen animal y vegetal, completa la relación de materiales que se utilizan para reponer la fertilidad en sus aspectos físicos, químicos y biológicos, mejorando tanto el aporte de nutrientes como las propiedades del suelo. El compostaje como técnica de tratamiento de los residuos se muestra como un método eficaz para mejorar estos materiales antes de su adición a las superficies de cultivo. Finalmente, la consideración de las enmiendas que se realizan en los suelos, los productos utilizados y sus efectos, completan este libro. Para acabar, se relaciona una serie de obras generales, algunas utilizadas para la redacción de esta obra, que nos permiten introducir al lector en diversos aspectos de la investigación y la docencia. Los autores, los profesores Ginés Navarro y Simón Navarro, catedráticos de la Universidad de Murcia, ponen a disposición de profesores y alumnos esta obra, fruto de una amplia experiencia docente e investigadora en el campo de la Química Agrícola que relaciona aquellos productos, los fertilizantes de síntesis y naturales, con las cualidades del suelo que permiten una mejor y mayor producción agrícola.
