Book Synopsis The Soils of the Philippines by : Rodelio B. Carating
Download or read book The Soils of the Philippines written by Rodelio B. Carating and published by Springer Science & Business. This book was released on 2014-04-23 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first soil survey in the Philippines was done by Mr. Clarence Dorsey, an American soil scientist in the province of Batangas in 1903. The Soils of the Philippines, however, is the first comprehensive summary of more than a century of soil-survey work in this country. It integrates the soil concepts of the reconnaissance soil-survey results, which commenced as early as 1934 and continued until the mid 1960s, with the semi-detailed soil surveys that continue to this day. The result is the first-ever genetic key for classifying Philippine soils at soil series level; thus, making it possible for any newcomers to the soil survey field to confidently produce their own soil map, at a more detailed map scale, to suit the project requirements. This book brings together discussions on soils and soil mapping units and up-to-date international techniques and technologies. It makes soils relevant to current political realities and national issues. As soil survey moves from a reductionist agricultural-development planning tool to a more holistic and integrated approach, to enable us to understand our dynamic and complex environment, The Soils of the Philippines will be the only source of authoritative and updated data on soil resources for macro-level resource management planning for decades to come. With a vanishing breed of experienced soil surveyors, not only in the Philippines but also worldwide, it may remain the only book on Philippine soils for the next hundred years or more. Since soils follow a geological and not a human time frame, the contents of this volume will stay relevant for soil surveyors even in a fast changing world. As the country leaps from an agricultural economy towards modernization and a more diversified economic base, some of the soil series in the Philippines, for example the Guadalupe series underlying the skyscrapers of Makati City, are becoming extinct as a result of urban development. Therefore, this book serves as the repository for the soils that we possess, the soils that have been lost through decades of urbanization while, at the same time, it creates a soil classification system for the soils we are yet to discover.

Download or read book Agricultural Input and Environment written by S.P. Palaniappan and published by Scientific Publishers. This book was released on 1995-01-01 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: After green revolution was launched in India, substantial increase in the production of food-grains was achieved through the use of improved crop varieties and higher levels of inputs like fertilizers water and plant protection chemicals. This made the revolution possible but it has limitations of higher costs and of causing damage to the environment specially when inputs are not used efficiently and judiciously. A decline of yields are being reported from the green revolution belts of India, in spite of liberal application of fertilizers and other inputs. The environmental problems are now becoming real problems of the developing countries as well as developing world. This disturbing trend is attributed to soil degradation, multi nutrient deficiencies and pest and diseases build up. The use of chemical inputs increases yields for a limited period, but without good management there is rapid deterioration of land and water resources. Inefficient use of fertilizers results in polluting the environment, in addition to wastage of scarce resource. It is therefore, imperative to conserve and utilize optimally the available production resources like land, water and genetic diversity and to efficiently manage the agricultural inputs for sustaining high crop productivity on a long term basis, with minimum damage to ecological and socio-economic environment. In this context, publication of a reference book is timely and appropriate. As the scientists, students, planners, administrators and extensionists recognize the importance of environmental problems related to agriculture, but they need ready reference to learn more about the problems, plan research agenda and develop strategies to tackle the problems. Hence, an attempt has been made to compile the information and presents in a readable form in this book. The book not only covers the effect of excessive use of chemical inputs on environment but also the effect of other human activities on agricultural production. It is sure that the book will be of immense use of post-graduate students and research workers in agricultural and environmental sciences, extension workers, progressive farmers, officials of the department of agriculture, environment and pollution control board administrators, planners and policy makers and the technical staff working in the agricultural input industry.

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 Wetland Indicators by : Ralph W. Tiner
Download or read book Wetland Indicators written by Ralph W. Tiner and published by CRC Press. This book was released on 1999-04-21 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understand the current concept of wetland and methods for identifying, describing, classifying, and delineating wetlands in the United States with Wetland Indicators - capturing the current state of science's role in wetland recognition and mapping. Environmental scientists and others involved with wetland regulations can strengthen their knowledge about wetlands, and the use of various indicators, to support their decisions on difficult wetland determinations. Professor Tiner primarily focuses on plants, soils, and other signs of wetland hydrology in the soil, or on the surface of wetlands in his discussion of Wetland Indicators. Practicing - and aspiring - wetland delineators alike will appreciate Wetland Indicators' critical insight into the development and significance of hydrophytic vegetation, hydric soils, and other factors. Features Shows 55 color plates, documenting wetland indicators throughout the nation - with more than 34 soil plates and aerial photos Illustrates other wetland properties with more than 50 figures Provides over 60 tables, including extensive tables of U.S. wetland plant communities and examples for determining hydrophytic vegetation Contents Wetland Definitions Wetland Concepts for Identification and Delineation Plant Indicators of Wetlands and Their Characteristics Vegetation Sampling and Analysis for Wetlands Soil Indicators of Wetlands Wetland Identification and Boundary Delineation Methods Problem Wetlands and Field Situations for Delineation Wetland Classification Wetlands of the United States: An Introduction, With Emphasis on Their Plant Communities Wetland Mapping and Photointerpretation
Book Synopsis The Biogeochemistry of Submerged Soils by : Guy Kirk
Download or read book The Biogeochemistry of Submerged Soils written by Guy Kirk and published by John Wiley & Sons. This book was released on 2004-06-25 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Submerged soils and the wetlands they support are of huge practical importance: in global element cycles, as centres of biodiversity, in global food production. They are also uniquely interesting scientifically because of their peculiar biogeochemistry and the adaptations of plants and microbes to it. This book describes the physical, chemical and biological processes operating in submerged soils and governing their properties. It describes the transport processes controlling the fluxes of gases and solutes through the soil; the interchange of solutes between solid, liquid and gas phases; reduction and oxidation processes; biological processes in the soil and overlying water; and processes in the roots and rhizospheres of wetland plants. The dynamics of nutrients, toxins, pollutants and trace gases are then discussed in terms of these processes and in relation to wetland productivity and global element cycles. Written by a renowned expert in the field, this work will be invaluable to earth, environmental and agricultural scientists concerned with natural or man-made wetlands, and to advanced undergraduate and graduate studen ts of these topics.

Book Synopsis Guidelines for Soil Description by : Food and Agriculture Organization of the United Nations
Download or read book Guidelines for Soil Description written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2006 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils are affected by human activities, such as industrial, municipal and agriculture, that often result in soil degradation and loss. In order to prevent soil degradation and to rehabilitate the potentials of degraded soils, reliable soil data are the most important prerequisites for the design of appropriate land-use systems and soil management practices as well as for a better understanding of the environment. The availability of reliable information on soil morphology and other characteristics obtained through examination and description of the soil in the field is essential, and the use of a common language is of prime importance. These guidelines, based on the latest internationally accepted systems and classifications, provide a complete procedure for soil description and for collecting field data. To help beginners, some explanatory notes are included as well as keys based on simple test and observations.--Publisher's description.
Book Synopsis Wetland Management and Sustainable Livelihoods in Africa by : Adrian Wood
Download or read book Wetland Management and Sustainable Livelihoods in Africa written by Adrian Wood and published by Routledge. This book was released on 2013-06-19 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book the authors argue for a paradigm shift in the way African wetlands are considered. Current policies and wetland management are too frequently underpinned by a perspective that views agriculture simply as a threat and disregards its important contribution to livelihoods. In rural areas where people are entrenched in poverty, wetlands (in particular wetland agriculture) have a critical role to play in supporting and developing peoples' livelihoods. Furthermore, as populations rise and climate change takes grip they will be increasingly important. The authors argue that an approach to wetland management that is much more people focused is required. That is an approach that instead of being concerned primarily with environmental outcomes is centred on livelihood outcomes supported by the sustainable use of natural wetland resources. The authors stress the need for Integrated Water Resource Management and landscape approaches to ensure sustainable use of wetlands throughout a river catchment and the need for wetland management interventions to engage with a wide range of stakeholders. They also assess the feasibility of creating incentives and value in wetlands to support sustainable use. Drawing on nine empirical case studies, this book highlights the different ways in which sustainable use of wetlands has been sought, each case focusing on specific issues about wetlands, agriculture and livelihoods.

Book Synopsis Systems approaches for agricultural development by : Frits Penning de Vries
Download or read book Systems approaches for agricultural development written by Frits Penning de Vries and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: The symposium In the next decades, agriculture will have to cope with an ever-increasing demand for food and raw basic materials on the one hand, and with the necessity to use resources without further degrading or exhausting the environment on the other hand, and all this within a dynamic framework of social and economic conditions. Intensification, sustainability, optimizing scarce resources, and climate change are among the key issues. Organized thinking about future farming requires forecasting of consequences of alternative ways to farm and to develop agriculture. The complexity of the problems calls for a systematic approach in which many disciplines are integrated. Systems thinking and systems simulation are therefore indispensable tools for such endeavours. About 150 scientists and senior research leaders participated in the symposium 'Systems Approaches for Agricultural Development' (SAAD) at the Asian Institute of Technology (AIT), Bangkok, Thailand, in December 1991. The symposium had the following objectives: - to review the status of systems research and modeling in agriculture, with special reference to evaluating their efficacy and efficiency in achieving research goals, and to their application in developing countries; - to promote international cooperation in modeling, and increase awareness of systems research and simulation. The symposium consisted of plenary sessions with reviews of major areas in systems approaches in agriculture, plus presentations in two concurrent sessions on technical topics of systems research. Subjects of studies were from tropical and temperate countries.
