DOWNLOAD EBOOKPhosphorus (P) stands second to nitrogen in terms of its essentiality as a plant macronutrient, as well as due to its involvement in almost all plant developmental stages, primary and secondary plant metabolisms, maintenance of membrane structures, and in the structural skeleton of major biomolecules. An optimum P-supply also helps plants combat abiotic stress impacts. Most P in soil remains unavailable for uptake by plants. P-containing fertilizers are being added to agricultural lands to sustain high yields. Only the least amount of the applied P (20%–30%) is used by most cultivated plants, and the rest remains as legacy P (P surpluses), which eventually causes eutrophication. This book, Phosphorus in Soils and Plants, reviews P in soils and plants, P dynamics in the soil–water–sediment environment, the major roles of P in the photosynthetic dark phase-biochemical pathways, major approaches for the sustainable management of P in agriculture, main mechanisms underlying the role of P in the regulation of plant–microbe interactions in the rhizosphere, literature on the role of microbial phosphate solubilization in management of soil and plant nutrients, and insights into P recovery through waste transformation. This volume is an important resource for plant biologists involved in teaching or research who wish to advance their knowledge of P in soils and plants.

DOWNLOAD EBOOKStandardized methods and measurements are crucial for ecological research, particularly in long-term ecological studies where the projects are by nature collaborative and where it can be difficult to distinguish signs of environmental change from the effects of differing methodologies. This second volume in the Long-Term Ecological Research (LTER) Network Series addresses these issues directly by providing a comprehensive standardized set of protocols for measuring soil properties. The goal of the volume is to facilitate cross-site synthesis and evaluation of ecosystem processes. Chapters cover methods for studying physical and chemical properties of soils, soil biological properties, and soil organisms, and they include work from many leaders in the field. The book is the first broadly based compendium of standardized soil measurement methods and will be an invaluable resource for ecologists, agronomists, and soil scientists.

DOWNLOAD EBOOKThis book focuses on the recent trends in carbon management and up-to-date information on different carbon management strategies that lead to manage increasing concentration of atmospheric carbon dioxide. The growing evidence of climate change resulting from the continued increase of atmospheric carbon dioxide concentration has made it a high profile political–social and trade issue. The mean global average earth temperature rose by 0.6± 2°C during the second half of the century with the rate of 0.17°C/decade. As per GISS data in the year of 2017, it rose 0.9°C (1.62 °F) above the 1951-1980 mean global temperature. Recently World Meteorological Organization analyzes the past record temperature and found the past 10 years were the warmest years about 1.1°C above preindustrial level. Over the past decade, carbon management by various techniques has to come to fore as a way to manage carbon dioxide emissions contributing to climate change. The proposed book addresses the need for an understanding of sustainable carbon dioxide management technologies mainly focused on (a) minimizing carbon dioxide emission from sources; (b) maximizing environmentally sound recuse, reduce and recycling; (c)emerging technology toward carbon dioxide mitigation and d) converting carbon dioxide into valuable products form sustainable use. Other books related to carbon management attempt to cover the carbon capture and sequestration, carbon mineralization, utilization and storage but the topic of CO2 management strategies is not discussed in detail for sustainable development. Furthermore, this book also covers all physical, chemical and biological process for long-term capture, removal and sequestration of carbon dioxide from the atmosphere for sustainable management which is not described in other carbon management books. In order to meet CO2 emissions reduction target, a range of technological approaches, including development of clean fuels and clean coal technologies, adopting cleaner and more energy efficiency and conservation, developing renewable energy and implementing CCS technologies, will also be considered for sustainable future.

DOWNLOAD EBOOKConservation agriculture systems have long-term impacts on livelihoods, agricultural production, gender equity, and regional economic development of tribal societies in South Asia. This book presents South Asia as a case study, due to the high soil erosion caused by monsoon rainfall and geophysical conditions in the region, which necessitate conservation agriculture approaches, and the high percentage of people in South Asia relying on subsistence and traditional farming. The book takes an interdisciplinary approach to analyse systems at scales ranging from household to regional and national levels.

DOWNLOAD EBOOKThis book begins with an overview of current thinking on bioavailability, its definition, cutting-edge research in speciation and advancement in tools for assessing chemical bioavailability in the terrestrial environment. The second section of the book focuses on the role of chemical speciation in bioavailability. Section three addresses bioavailability and ecotoxicity of contaminants and leads into the next section on bioavailability of nutrients and agrichemicals. Subsequent sections provide an overview of tools currently being used and new cutting-edge techniques to assess contaminant bioavailability. The last section of the book builds on previous sections in relating bioavailability to risk assessment and how this could be used for managing risks associated with contaminated land. - Provides the latest information on developing concepts and definitions of bioavailability - Includes a discussion of bioavailability and ecotoxicity of contaminants and bioavailability of nutrients and agrichemicals for applications in agriculture - Analyzes tools for assessing bioavailability and the role of bioavailability in risk assessment and remediation

DOWNLOAD EBOOKThe book provides reader with a comprehensive up-to-date overview of various aspects of soil pollutants manifestation of toxicity. The book highlights their interactions with soil constituents, their toxicity to agro-ecosystem & human health, methodologies of toxicity assessment along with remediation technologies for the polluted land by citing case studies. It gives special emphasis on scenario of soil pollution threats in developing countries and ways to counteract these in low cost ways which have so far been ignored. It also explicitly highlights the need for soil protection policy and identifies its key considerations after analyzing basic functions of soil and the types of threats perceived. This book will be a useful resource for graduate students and researchers in the field of environmental and agricultural sciences, as well as for personnel involved in environmental impact assessment and policy making.
