The Guayana Highlands in northeastern tropical America, rising from lowland rain forests and savannas up to 3000 m elevation, are characterized by ancient tablelands called "tepuis." The peatlands that developed on the tepuis constitute unique and fascinating ecosystems and are the focus of this volume, which starts with an overview of tropical and subtropical peats, followed by an introduction to the geo-ecological features of the Guayana region as a whole, with special emphasis on the diversity of the vegetation cover from lowlands to uplands to highlands. The core subject centers on the properties and dating of the peat deposits and the interpretation of the chronological record in terms of past environmental changes. The well illustrated book will appeal to a broad range of scientists interested in tropical highland peats, including quaternarists, soil scientists, geomorphologists, geographers, geologists, ecologists, botanists, hydrologists, conservationists, and land use planners.

Soil quality is threatened by many human-induced activities, but can also be improved by good land management. In the relatively short history of mankind on earth, the landscape and soils of the world have been drastically modified from their "natural " state. Landscapes altered by man's activities are termed "Anthroscapes" which are inextricably linked to culture and history. The challenges for today's scientists are to devise and implement sustainable land management strategies in order to preserve the land for the benefit of future generations. This book is a valuable compendium of the research experiences so far gained in studies of the context and concept of the "Anthroscape" and highlights the potential future contributions of such research to sustainable development.
In any ecosystem, plant and microbe interaction is inevitable. They not only co-exist but also support each other's survival and provide sustenance in stressful environments. Agro-ecosystems in many regions around the globe are affected by high temperatures, soil salinity/alkalinity, low pH and metal toxicity. High salinity and severe draught are other major constraints affecting agricultural practices and also plants in the wild. A major limiting factor affecting global agricultural productivity is environmental stresses. Apart from decreasing yield, they also have a devastating impact on plant growth. Plants battle with various kind of stresses with the help of symbiotic associations with the rhizospheric microbes. Naturally occuring plant-microbe interactions facilitate the survival of plants under these stressful conditions. The rhizosphere consists of several groups of microbes, plant growth-promoting bacteria (PGPB) is one such group of microbes that assists plants in coping with multiple stresses and also promote plant growth. These efficient microbes support the stress physiology of the plants and can be extremely useful in solving agricultural as well food- security problems. This book provides a detailed, holistic description of plant and microbe interaction. It elucidates various mechanisms of nutrient management, stress tolerance and enhanced crop productivity in the rhizosphere, discussing The rhizospheric flora and its importance in enhancement of plant growth, nutrient content, yield of various crops and vegetables as well as soil fertility and health. Divided into two volumes, the book addresses fundamentals, applications as well as research trends and new prospects for agricultural sustainability. Volume 1: Stress Management and Agricultural Sustainability, includes chapters offering a broad overview of plant stress management with the help of microbes. It also highlights the contribution of enzymatic and molecular events occurring in the rhizosphere due to plant microbe interactions, which in turn help in the biological control of plant disease and pest attacks. Various examples of plant microbe interaction in rhizospheric soil are elaborated to facilitate the development of efficient indigenous microbial consortia to enhance food and nutritional security. Providing a comprehensive information source on microbes and their role in agricultural and soil sustainability, this timely research book is of particular interest to students, academics and researchers working in the fields of microbiology, soil microbiology, biotechnology, agronomy, and the plant protection sciences, as well as for policy makers in the area of food security and sustainable agriculture.
This book is the first to systematically explore experimental erosion by integrating theory, erosion observations, and conservation applications. Although numerous books have been published on soil erosion both in English and in Chinese, none has concentrated on experimental studies on the Loess Plateau of China, in an attempt to establish a new sub-discipline: experimental erosion. One main objective of this book is to highlight monitoring and modeling methods for soil scientists who design and conduct experimental studies on soil loss. Another objective, and the most important one, is to make the results of these experiments more generally available. Accordingly, we have gathered and integrated a broad range of experimental results, both published and unpublished. In-depth discussions of the experimental data and new data processing methods are also included. The work covered here represents exemplary studies in the field of soil erosion and conservation, while the new methods and findings presented will provide practical guidance for controlling soil erosion. Hence the book offers a valuable resource for graduate students, soil erosion scientists and engineers, and soil and water conservationists.
One of the main problems confronting the world of the 21st Century is a shortage of water. There is already severe scarcity in many regions of the world, causing tremendous problems for local populations and indeed entire societies. There is insufficient water available for the production of food to alleviate poverty and starvation; the lack of water hampers industrial, urban and tourism development, forcing restrictions on other sectors, especially agriculture; health problems arise as the deterioration of ground and surface waters favours water-borne diseases, which flourish in the absence of decent water distribution and sewerage systems. Water conflicts still arise in areas under stress, while water for nature has become a vanishing priority in such zones. This book is a guide to the establishment of regional and/or local guidelines for developing and implementing new ideas for coping with water scarcity. The basic premise underlying the book is that water scarcity will persist, so personal, human and society-wide skills will be needed to cope with it while living in harmony with the necessary environmental constraints. The book provides basic information to assist decision makers, water managers, engineers, agronomists, social scientists and other professions (and their students) in formulating coherent, hopefully harmonious and consolidated views on the issue. Guidelines are also given for introducing the general public to the concept of water scarcity and how to deal with it.
This book is an open access publication. Forest ecosystems in Central Europe are changing as a result of anthropogenic influences and changing climate conditions. As such, a large-scale monitoring programme was undertaken in order to understand the influence of site modification, deposition of air pollutants, and climate. This book presents the scientific findings of this study for Germany, including the major challenges with regard to the future preservation and management of forest ecosystems under environmental change. In addition, it addresses a number of central questions: what are the main factors affecting forest stands and soil integrity? How, and how rapidly, are forest ecosystems changing? How diverse are the changes across Germany? What will be the main risks in sustainable forest management in the future? And how can policy support the development and maintenance of adaptive and resilient forests that provide essential ecosystem services, today and in the future? Helping readers understand the importance of soils and related ecosystem processes for future sustainable forestry, and sharing essential findings on environmental change and related changes in forest status and dynamics, the book is a valuable resource for researchers and policymakers interested in science-based decisions.

The only way that millions of people can exist in developing countries is by farming whatever land is available to them. For these people, it is vital that productivity of the land is not only maintained but improved. This manual is for rural development workers faced with land degradation.
In large parts of the developed and developing worlds soil tillage by plough or hoe is the main cause of land degradation leading to stagnating or even declining production levels and increasing production cost. It causes the soil to become more dense and compacted, the organic matter content to be reduced and water runoff and soil erosion to increase. It also leads to droughts becoming more severe and the soil becoming less fertile and less responsive to fertiliser. This book brings together the key notes lectures and other outstanding contributions of the I World Congress on Conservation Agriculture and provides an updated view of the environment and economic advantages of CA and of its implementation in diferent areas of the World.

In addition to being a reliable reference, it is valuable as an advanced text from which topics of interest can be selected by the teacher and student.
The soil water retention curve, the saturated hydraulic conductivity and the unsaturated hydraulic conductivity function are basic soil hydraulic functions and parameters. Ample apprehension of the soil hydraulic functions and parameters is required for a successful formulation of the principles leading to sustainable soil management, agricultural production and environmental protection. From these, all the other parameters, required in the solution of the practical tasks, are derived. The basic soil hydraulic functions are strongly dependent upon the soil porous system. The development of models is characteristic by the gradual transition from the simplest concepts up to the sophisticated approaches, which should correspond to the visual reality studied by soil micromorphology. 2 Soil Porous System and Soil Micromorphometry 2.1 An Overview on the Quantification of the Soil Porous System Quanti? cation of the soil porous system consists of classi? cation of soil pores, ch- acterization of the soil pores shapes and the estimation of the pore size distribution function. When the hydraulic functions of the soil pores are considered, the following laws of hydrostatics and hydrodynamics are applied as best ? tting to the classi? cation criteria of the size of the pores (Kutilek and Nielsen 1994, p. 20, Kutilek 2004): A. Submicroscopic pores that are so small that they preclude clusters of water molecules from forming ? uid particles or continuous water ? ow paths.
The book gives a detailed description of the application of DSSAT in simulating crop and soil processes within various Agro-ecological zones in Africa. The book, an output of a series of 3 workshops, provides examples of the application of DSSAT models to simulate nitrogen applications, soil and water conservation practices including effects of zai technology, phosphorus and maize productivity, generation of genetic coefficients, long-term soil fertility management technologies in the drylands, microdosing, optimization of nitrogen x germplasms x water, spatial analysis of water and nutrient use efficiencies and, tradeoff analysis. The minimum dataset requirements for DSSAT is discussed. This book arises from attempts to address the limited use of models in decision support by African agricultural (both soil scientist and agronomists) scientists.
Despite its many origins in agronomic problems, statistics today is often unrecognizable in this context. Numerous recent methodological approaches and advances originated in other subject-matter areas and agronomists frequently find it difficult to see their immediate relation to questions that their disciplines raise. On the other hand, statisticians often fail to recognize the riches of challenging data analytical problems contemporary plant and soil science provides.
With the increasing concern over rural livelihoods and the food security of poor communities in developing countries, it is vital that land quality is maintained. Yet, land degradation is widespread and is lowering the productive capacity of the land in these countries. This practical handbook presents simple, non-technical indicators for assessing land degradation in the field. Based on the perspective of the farmer, the methods selected lend meaning to real farming situations, helping the field professional to understand not only the impact of degradation but also the benefits to be gained from reversing it. The handbook shows how to calculate indicators such as those of soil loss, explains the interpretation of results and in particular how combinations of different indicators can give conclusive evidence of the severity of land degradation. The focus of the book is firmly on understanding the farmer's interaction with the land, and how environmental protection, food security and the well-being of rural land users may be assured. With detailed figures, photographs, worked examples and sample forms based on assessment techniques validated by field professionals in Africa, Asia and Latin America, this will be an essential training manual will be invaluable for field-workers in NGOs and in governmental and educational institutions. It will also be of interest to researchers and academics in development, environment and agriculture.

In Awakening the Dreamer: Clinical Journeys, Philip Bromberg
continues the illuminating explorations into dissociation and
clinical process begun in Standing in the Spaces (1998). Bromberg
is among our most gifted clinical writers, especially in his unique
ability to record peripheral variations in relatedness - those
subtle, split-second changes that capture the powerful workings of
dissociation and chart the changing self-states that analyst and
patient bring to the moment.
An exploration of how the many sciences of wine can enhance our appreciation and enjoyment of wine. In From Terrain to Brain, Professor Erika Szymanski makes wine science accessible to non-experts. Rather than approach wine science as body of facts about wine, Szymanski explores how wine science can open up multiple ways of seeing, understanding, and appreciating wine. Too often, wine science is presented as a comprehensive body of knowledge that enthusiasts aiming to become experts should memorize. This book instead uses scientific research to explore wine as an endlessly rich cultural phenomenon. By foregrounding recent research and developments in wine science, From Terrain to Brain presents wine science as a work-in-progress rather than a codified body of knowledge. Each chapter takes readers on a journey or "foray" through a topic in wine science, such as minerality, climate, microbiome, and yeast. Chapters are organized from "terrain" (geography, terroir, soil) and cell "membrane" (microbiology) through "brain" (the experience of tasting) and "drain" (sustainability). Throughout, From Terrain to Brain emphasizes that wine science, wine culture, and tradition are interconnected and places scientific research in social and historical context.
The importance of magnesium in the element cycling of forest ecosystems has only been fully recognized since the widespread symptoms of forest magnesium deficiency were identified to be a major component in the damage phenomena. The intensive research during the last 15 years revealed not only details on the role of magnesium as a nutrient in forest ecosystems, but led also to a more comprehensive understanding of these ecosystems themselves and their functioning. This book tries to summarize the knowledge of magnesium and its role in forest ecosystems gathered from recent studies as well as from historical experiences and findings. The results of these studies in most cases point to the activity of man and his influence on the ecosphere. Therefore, when we understand the processes and effects described in this book, perhaps we can learn not only about a single nutrient like magnesium and forest ecosystems but also about ourselves.
For more than 30 years, soil testing has been widely used as a basis for determining lime and fertilizer needs. Today, a number of procedures are used for determining everything from soil pH and lime requirement, to the level of extractable nutrient elements. And as the number of cropped fields being tested increases, more and more farmers and growers will come to rely on soil test results. But if soil testing is to be an effective means of evaluating the fertility status of soils, standardization of methodology is essential. No single test is appropriate for all soils.
Soil Science is an important and basic science in agriculture which deals with different domains of soil research namely, soil formation, genesis and classification, soil physics, soil chemistry, soil fertility and plant nutrition, soil biology, etc. Characterization as well as our understanding of soils requires that they are precisely analysed and described. While the physical properties of soils determine their adaptability to cultivation, chemical properties tells about their chemical environment and nutrient status to the crop production - the most important use of soils on this densely populated planet. Determination of different soil physical and chemical properties in the field or in the laboratory following suitable analytical methods is first step towards appropriate soil managements and scientific recommendations for increasing crop production. |
