Book Synopsis Function of Soils for Human Societies and the Environment by : Emmanuel Frossard
Download or read book Function of Soils for Human Societies and the Environment written by Emmanuel Frossard and published by Geological Society of London. This book was released on 2006 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers in this volume address issues of soil formation, soil management, soil protection and the role of biodiversity that must be considered for a sustainable soil use. The papers are aimed at geoscientists in the broadest sense, and others concerned with soil use who will also find chapters relevant to their interests. Soils knowledge used within other Earth sciences is essential for maintaining healthy ecosystems, for the solutions of problems in environmental quality and for sustainable use of soils by humans.

Book Synopsis Managing Organic Matter in Tropical Soils: Scope and Limitations by : Christopher Martius
Download or read book Managing Organic Matter in Tropical Soils: Scope and Limitations written by Christopher Martius and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil organic matter is a reservoir for plant nutrients, provides water-holding capacity, stabilizes soil structure against compaction and erosion, and thus determines soil productivity. All agriculture to some degree depends on soil organic matter. It has long been known that soil organic matter declines when land is taken into cultivation, and that the productivity of new agricultural land is governed by fertility contributions from decomposing natural organic matter. The expansion of agriculture to ever new and more fragile lands, particularly in tropical and developing regions, causes environmental degradation with local effects on soil quality, regional effects on landscape integrity and water quality, and global effects on carbon cycles and the atmosphere. This book summarizes current knowledge of the properties and dynamics of soil organic matter in the tropics, its role in determining soil quality, its stability and turnover, and the options for management in the context of tropical landuse systems, for a readership of resource scientists, economists and advanced students. Maintenance of organic matter is critical for preventing land degradation. Case studies and practical applications are therefore an important part of the book, as are the exploration of future directions in research and management.

Book Synopsis Fertility of Soils by : Christian J.M.G. Pieri
Download or read book Fertility of Soils written by Christian J.M.G. Pieri and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Can a continuous growth of agriculture be achieved in the sub-Sahara region without inducing irreversible damage to the ecosystem? Until now, doubts have been expressed as to the actual capacity of the soils to sustain a desirable increase of production which can match the requirements of a fast-growing population. Thirty years of investigation and a renewed comprehensive interpretation of research data on soil fertility show that a sustainable agriculture growth could be a practical possibility in a savannah region.

Book Synopsis Structure and Organic Matter Storage in Agricultural Soils by : M.R. Carter
Download or read book Structure and Organic Matter Storage in Agricultural Soils written by M.R. Carter and published by CRC Press. This book was released on 2020-12-18 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils comprise the largest pool of terrestrial carbon and therefore are an important component of carbon storage in the biosphere-atmosphere system. Structure and Organic Matter Storage in Agricultural Soils explores the mechanisms and processes involved in the storage and sequestration of carbon in soils. Focusing on agricultural soils - from tropical to semi-arid types - this new book provides an in-depth look at structure, aggregation, and organic matter retention in world soils. The first two sections of the book introduce readers to the basic issues and scientific concepts, including soil structure, underlying mechanisms and processes, and the importance of agroecosystems as carbon regulators. The third section provides detailed discussions of soil aggregation and organic matter storage under various climates, soil types, and soil management practices. The fourth section addresses current strategies for enhancing organic matter storage in soil, modelling techniques, and measurement methods. Throughout the book, the importance of the soil structure-organic matter storage relationship is emphasized. Anyone involved in soil science, agriculture, agronomy, plant science, or greenhouse gas and global change studies should understand this relationship. Structure and Organic Matter Storage in Agricultural Soils provides an ideal source of information not only on the soil structure-storage relationship itself, but also on key research efforts and direct applications related to the storage of organic matter in agricultural soils.

Book Synopsis La Caraïbe, données environnementales by :
Download or read book La Caraïbe, données environnementales written by and published by KARTHALA Editions. This book was released on 2006 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: A l'interface des continents nord et sud américains, la Caraïbe se caractérise par de grandes disparités sociétales et biologiques. A la pluralité des environnements physiques correspond une diversité floristique, faunistique, écosystémique et paysagère. Ressource primordiale pour les Amérindiens, les écosystèmes terrestres et marins sont aujourd'hui à l'intersection d'intérêts divers relevant de l'économique et du culturel ou encore de l'aménagement territorial. Les spécificités écologiques, qui sont fonction des différentes terres caribéennes, sont à la base d'usages nouveaux susceptibles de participer au développement économique, par exemple le tourisme. A cette histoire singulière, façonnée par l'action des hommes, s'ajoutent les incommodités naturelles telluriques et atmosphériques, dont les effets directs et indirects ont érigé certaines composantes de cette partie de la biosphère en terre à risques. Les nuisances de toutes sortes, inhérentes au fonctionnement de ces sociétés, sont des freins au développement maîtrisé ou soutenable. Pour l'essentiel, les économies relèvent des propriétés du mal-développement et peuvent entraîner, dans des cas extrêmes, un chaos politique et social. Les conséquences pour les milieux biophysiques sont souvent graves et s'apparentent à un écocide (Haïti par exemple). Le but premier de ce numéro de Terres d'Amérique est d'explorer les différentes facettes du fonctionnement des sociétés caribéennes ainsi que leurs dynamiques d'interface au regard des environnements physiques et biologiques.
Download or read book Pedology written by R. Duchaufour and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first of two volumes intended to replace the old and now out of print Precis de pedologie, the previous three editions of which were pro duced by the same publisher in 1960, 1965 and 1970. It was apparent that the term 'precis', which means that the text was neces sarily condensed and summarised, no longer corresponded with the present day situation, for pedology has developed considerably in the past 10 years and it now makes use of the most modern and varied research techniques. It has become an entirely separate discipline and has assumed, at least in certain countries, considerable importance. In addition, different schools of thought have developed and their sometimes contradictory viewpoints are presented at many international conferences, which, if valid conclusions are to be reached from them, required considerable space for discussion. Thus, even by being very concise it was no longer possible to deal with the whole of soil science within the space of one volume, so that a two volume format became a necessity. As soil science is known to have two fundamentally distinct aspects, it has been easy to determine the contents of each volume and also to give each an identity and unity, as well as enabling a different kind of presentation to be made in each case.
