This volume presents the proceedings of the 10th internationalsymposium Humus et Planta held in Prague in August 19-23,1991. The main topics of this book are devoted to the recentadvances in fundamental, as well as applied research of humicsubstances, the most abundant of the naturally occuringmacromolecules of nature, the understanding of their natureand how they react and interact in their natural environments.Texts are included on the structure, physical and chemicalproperties of humic substances; the relationships among humus,soil properties and fertility; the biotransformations oforganic substances in the soil; the relationships betweenhumic substances and plants and the interactions of humus andxenobiotic substances. This book presents recent knowledge ofthe complicated and challenging humic substances. It will beof interest not only to scientist, but also to Universityteachers and students of agricultural and environmentalsciences.

This book highlights the increasing importance of humic substances in the different scientific fields related to terrestrial ecology, soil quality conservation, and environmental chemistry. It shows that modern humic substances research is not only directed to unravel their yet ill-defined chemical structure but is successfully exploring the interconnected chemical, biological, and physical processes that maintain the ecological equilibrium of soil and ensure a sustainable agricultural production.The book will primarily be of interest to soil scientists and to ecological and environmental scientists. People in the fields of forest science, agronomy, analytical and environmental chemistry, water science, environmental engineering, and coal science will also find this publication worthy of their attention.

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.

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.

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.

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.

Soil Physical Chemistry, Second Edition takes up where the last edition left off. With comprehensive and contemporary discussions on equilibrium and kinetic aspects of major soil chemical process and reactions this excellent text/reference presents new chapters on precipitation/dissolution, modeling of adsorption reactions at the mineral/water interface, and the chemistry of humic substances. An emphasis is placed on understanding soil chemical reactions from a microscopic point of view and rigorous theoretical developments such as the use of modern in situ surface chemical probes such as x-ray adsorption fine structure (XAFS), Fournier transform infrared (FTIR) spectroscopies, and scanning probe microscopies (SPM) are discussed.
