Download or read book Digital Soil Morphometrics written by Alfred E. Hartemink and published by Springer. This book was released on 2018-04-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about digital soil morphometrics which is defined as the application of tools and techniques for measuring, mapping and quantifying soil profile properties, and deriving depth functions of soil properties. The book is structured along four research topics: (i) Soil profile properties, (ii) Soil profile imaging, (iii) Soil depth functions, and (iv) Use and applications. The pedon is at the heart of digital soil morphometrics. The use of digital soil morphometrics exceeds the pedology and soil classification purpose that it currently serves – it is used in rapid soil assessment that are needed in a range of biophysical studies. Digital soil morphometrics has the potential to enhance our understanding of soils and how we view them. The book presents highlights from The IUSS Inaugural Global Workshop on Digital Soil Morphometrics held in June 2015 in Madison, USA.

Download or read book Soil Fertility Decline in the Tropics written by Alfred E. Hartemink and published by CABI. This book was released on 2003 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wide coverage of soils and perennial cropping systems in the tropicsSynthesis of decades of researchChallenges assumptions on the benefits of plantations for soil fertilityIt is generally assumed that soil fertility decline is widespread in the tropics and that this is largely associated with annual cropping and subsistence farming. In contrast, perennial plant cover (as in plantation agriculture) provides better protection for the soil.This book reviews these concepts, focusing on soil chemical changes under different land-use systems in the tropics. These include perennial crops, annual crops and forest plantations. Two case studies, on sisal plantations in Tanzania and sugar cane in Papua New Guinea, are presented for detailed analysis. The author demonstrates that soil fertility decline is also a problem on plantations.

Download or read book The Soil Underfoot written by G. Jock Churchman and published by CRC Press. This book was released on 2014-04-21 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: The largest part of the world’s food comes from its soils, either directly from plants, or via animals fed on pastures and crops. Thus, it is necessary to maintain, and if possible, improve the quality—and hence good health—of soils, while enabling them to support the growing world population. The Soil Underfoot: Infinite Possibilities for a Finite Resource arms readers with historical wisdom from various populations around the globe, along with current ideas and approaches for the wise management of soils. It covers the value of soils and their myriad uses viewed within human and societal contexts in the past, present, and supposed futures. In addition to addressing the technical means of maintaining soils, this book presents a culturally and geographically diverse collection of historical attitudes to soils, including philosophical and ethical frameworks, which have either sustained them or led to their degradation. Section I describes major challenges associated with climate change, feeding the increasing world population, chemical pollution and soil degradation, and technology. Section II discusses various ways in which soils are, or have been, valued—including in film and contemporary art as well as in religious and spiritual philosophies, such as Abrahamic religions, Maori traditions, and in Confucianism. Section III provides stories about soil in ancient and historic cultures including the Roman Empire, Greece, India, Japan, Korea, South America, New Zealand, the United States, and France. Section IV describes soil modification technologies, such as polymer membrane barriers, and soil uses outside commercial agriculture including the importance of soils for recreation and sports grounds. The final section addresses future strategies for more effective sustainable use of soils, emphasizing the biological nature of soils and enhancing the use of "green water" retained from rainfall.

Download or read book Forest Soils written by Khan Towhid Osman and published by Springer Science & Business Media. This book was released on 2013-12-12 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest soil characteristics are not only unique but their interpretation also differs from cropland soils. Just as there are diverse forest types, there are many soil variants that need different management. Today, forest plantations are being intensively managed for profitable timber, pulpwood and energy production. Site selection, species selection, site productivity evaluation, silvicultural treatments, and soil amendments need crucial soil information. This book provides a comprehensive overview of the physical, chemical and biological properties of forest soils and their implications on forest vegetation. Topics discussed include: major forest types of the world and their associated soils; forest biomass and nutrient dynamics; organic matter turnover and nutrient recycling; forest soil disturbance; forest soil and climate change; and forest soil management and silvicultural treatments.

Download or read book Heavy Metal Stress in Plants written by Dharmendra K. Gupta and published by Springer Science & Business Media. This book was released on 2013-08-04 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants possess a range of potential cellular mechanisms that may be involved in the detoxification of heavy metals and thus tolerance to metal stress. Metal toxicity causes multiple direct and indirect effects in plants that concern practically all physiological functions. The main purpose of this book is to present comprehensive and concise information on recent advances in the field of metal transport and how genetic diversity affects heavy metal transport in plants. Other key futures of the book are related to metal toxicity and detoxification mechanisms, biochemical tools for HM remediation processes, molecular mechanisms for HM detoxification, how metallomics and metalloproteomics are affected by heavy metal stress in plants, and the role of ROS metabolism in the alleviation of heavy metals. Some chapters also focus on recent developments in the field of phytoremediation. Overall the book presents in-depth information and the most essential advances in the field of heavy metal toxicity in plants in recent years.

Download or read book Materiality Techniques and Society in Pottery Production written by Daniel Albero Santacreu and published by Walter de Gruyter GmbH & Co KG. This book was released on 2014-01-01 with total page 619 pages. Available in PDF, EPUB and Kindle. Book excerpt: Daniel Albero Santacreu presents a wide overview of certain aspects of the pottery analysis and summarizes most of the methodological and theoretical information currently applied in archaeology in order to develop wide and deep analysis of ceramic pastes. The book provides an adequate framework for understanding the way pottery production is organised and clarifies the meaning and role of the pottery in archaeological and traditional societies. The goal of this book is to encourage reflection, especially by those researchers who face the analysis of ceramics for the first time, by providing a background for the generation of their own research and to formulate their own questions depending on their concerns and interests. The three-part structure of the book allows readers to move easily from the analysis of the reality and ceramic material culture to the world of the ideas and theories and to develop a dialogue between data and their interpretation. Daniel Albero Santacreu is a Lecturer Assistant in the University of the Balearic Islands, member of the Research Group Arqueo UIB and the Ceramic Petrology Group. He has carried out the analysis of ceramics from several prehistoric societies placed in the Western Mediterranean, as well as the study of handmade pottery from contemporary ethnic groups in Northeast Ghana.

Download or read book Networks on Networks written by Allen G Hunt and published by Iop Concise Physics. This book was released on 2016 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Order from chaos is simultaneously a mantra of physics and a reality in biology. Physicist Norman Packard suggested that life developed and thrives at the edge of chaos. Questions remain, however, as to how much practical knowledge of biology can be traced to existing physical principles, and how much physics has to change in order to address the complexity of biology. Phil Anderson, a physics Nobel laureate, contributed to popularizing a new notion of the end of "reductionism." In this view, it is necessary to abandon the quest of reducing complex behavior to known physical results, and to identify emergent behaviors and principles. In the present book, however, we have sought physical rules that can underlie the behavior of biota as well as the geochemistry of soil development. We looked for fundamental principles, such as the dominance of water flow paths with the least cumulative resistance, that could maintain their relevance across a wide range of spatial and temporal scales, together with the appropriate description of solute transport associated with such flow paths. Thus, ultimately, we address both nutrient and water transport limitations of processes from chemical weathering to vascular plant growth. The physical principles guiding our effort are established in different, but related concepts and fields of research, so that in fact our book applies reductionist techniques guided by analogy. The fact that fundamental traits extend across biotic and abiotic processes, i.e., the same fluid flow rate is relevant to both, but that distinctions in topology of the connected paths lead to dramatic differences in growth rates, helps unite the study of these nominally different disciplines of geochemistry and geobiology within the same framework. It has been our goal in writing this book to share the excitement of learning, and one of the most exciting portions to us has been the ability to bring some order to the question of the extent to which soils can facilitate plant growth, and what limitations on plant sizes, metabolism, occurrence, and correlations can be formulated thereby. While we bring order to the soil constraints on growth, we also generate some uncertainties in the scaling relationships of plant growth and metabolism. Although we have made an first attempt to incorporate edaphic constraints into allometric scaling, this is but an initial foray into the forest.
