Structure and Organic Matter Storage in Agricultural Soils by M.R. Carter,B.A. Stewart Pdf

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.

Bioactive Compounds in Agricultural Soils by Lech Wojciech Szajdak Pdf

This volume looks at the impact that different cropping systems and tillage have on soil’s biologically active substances. It considers how phytotoxins accumulate and can inhibit the development of cultivated plants. Coverage explores the continuous cropping of rye, crop rotation, no tillage, and conventional tillage. It offers a comprehensive, comparative approach to allelopathic plant-soil interactions. The authors focus on free and bounded biologically active substances such as amino acids, auxins, humic and fulvic acids, transient radicals, and enzymes in light sand soils fertilized with different mineral and organic fertilizers. The chapters address fundamental questions relevant to the environmental challenges we face today and will deal with in the future. The results involve asking basic questions motivated by soil's chemical and biochemical processes. The answers will lead to the improvement of the quality of soil’s organic matter, which, in turn, can lead to increased crop yields. Readers will come to understand the relationship between ecological processes and environmental change on individual levels of biocomplexity as well as on systems in their entirety. The title is ideal for students and teachers for laboratory practical classes. Soil scientists, biochemists, chemists, plant ecophysiologists, “Natural Products” organic chemists, and other environmental scientists and specialists will also find it useful.

Carbon and Nitrogen in the Terrestrial Environment by R. Nieder,D.K. Benbi Pdf

Carbon and Nitrogen in the Terrestrial Environment is a comprehensive, interdisciplinary description of C and N fluxes between the atmosphere and the terrestrial biosphere; issues related to C and N management in different ecosystems and their implications for the environment and global climate change; and the approaches to mitigate emission of greenhouse gases. Drawing upon the most up-to-date books, journals, bulletins, reports, symposia proceedings and internet sources documenting interrelationships between different aspects of C and N cycling in the terrestrial environment, Carbon and Nitrogen in the Terrestrial Environment fills the gap left by most of the currently available books on C and N cycling. They either deal with a single element of an ecosystem, or are related to one or a few selected aspects like soil organic matter (SOM) and agricultural or forest management, emission of greenhouse gases, global climate change or modeling of SOM dynamics.

Managing Organic Matter in Tropical Soils: Scope and Limitations by Christopher Martius,Holm Tiessen,Paul L.G. Vlek Pdf

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.

Soil Pollution by Ibrahim Mirsal Pdf

Despite having been published about two years ago for the first time, the continuous demand for this book encouraged me to prepare this revised and enlarged edition. Many parts of the text have been rewritten, type errors traced and corrected, and the bibliography largely modified to include many of the references published about the subject of soil pollution in the previous ten years. I should like to express my thanks to the staff of Springer-Verlag, Heidelberg, for their cooperative efforts in preparing this edition. I also would like to thank Mr. Michael Sidwell (B.A.) for the extreme but characteristic care with which he read and revised the proofs. I hope that, in this new edition, the book may continue to serve the needs of students and professionals alike interested in the subject of soil pollution. Ibrahim A. Mirsal Preface to the First Edition Whoever has enjoyed following the legendary duel between the Egyptian Pharaoh and his magicians (Alchemists) on one side, and Moses and his brother Aaron on the other, as is vividly narrated in the Bible, must have realised that people (at least those living at, or near the eternal battlefields of the Middle East) have always had knowledge about the terrible consequences of soil pollution by chemicals. This knowledge must have existed long before Moses and his Pharaoh. Nobody knows when people became aware of this, yet it must have been born in very early times, reaching back to the dawn of human conscious.

Structure and Functioning of Seminatural Meadows by M. Rychnovská Pdf

Twelve years' analysis of natural grassland and experimentally managed meadows have produced this unique set of data on the structures and physiological functions of primary producers, consumers and decomposers. Obtained during the 1973-1985 Ecosystem Study on Highland Meadows in Czechoslovakia, such original information is rare in scientific literature. The aim of the study was to define the functioning of these grasslands and their changes under different impact of man, and to examine the ecological function of those ecosystems in the intensively managed catchment area. Hence, this book contains deep analyses of soil microorganisms, their functions in decomposition and soil forming processes - leading to the evaluation of the whole carbon cycle - as well as dealing with nitrogen pathways in the experimental plots - resulting in precise determination of the full nitrogen cycle. Procedures used in practical agriculture, such as cutting, fertilization and renovation, have also been applied, producing evaluations from both ecological and economical view-points. The book's integrated ecosystem approach to grasslands, its deep professional analyses in each section, along with the synthesis on each particular level and across all levels, renders it an invaluable, informative text, comprising extensive figures and tables and a substantial bibliography of world-wide sources.

The Science of Composting by Marco de Bertoldi Pdf

The European Union initially demonstrated its interest in waste in the late 70s with the progamme on Waste Recycling Research and Development. At that time composting was only present as a coordination activity and it was only later that specific research programmes in the area were within Europe which was largely instrumental in setting up a series of European conferences, seminars and work shops. Some of these have resulted in publications which have made significant contributions to developments in the understanding of composting and the use of composts. In particular the outputs from meetings in Oxford ( 1984), Udine (1986), Neresheim ( 1988) and Angers ( 1991) are worthy of note. Composting has seen significant changes since the 70s when the major thrust in Europe was using mixed municipal solid waste as a feed material. Many com posting plants which were built to use this material were closed due to the poor quality of the compost which made it very difficult to market. As a result the main areas of interest, as far as the municipa1ities are concemed, are now with biowaste and source-separated organics. This interest is apparent from the many new plants which are being constructed across Europe, and the ready market which exists for the products. In parallel with the renewed interest of the municipalities other areas, such as agriculture and the wastewater treatment industries, are also developing their own schemes.

Development of Pedotransfer Functions in Soil Hydrology by Y. Pachepsky,W.J. Rawls Pdf

Environmental and agricultural modeling and assessment have a multitude of uses for soil parameters governing retention and transport of water and chemicals in soils. These parameters are notorious for the difficulties and high labor costs involved in measuring them. Good estimates instead of direct measurements may be accurate enough for many applications. Pedotransfer functions provide such estimates by utilizing available soil survey information to translate data we have into data we need. This book is the first book on the topic. It provides the unique compendium of pedotransfer functions, summarizes the vast international experience in this field, and shows how the value of soil data can be increased by using them in pedotransfer functions to predict soil hydrologic and related properties. The book is a rich source of information crucial for environmental research and applications.
