Download or read book Ecosystem Services and Carbon Sequestration in the Biosphere written by Rattan Lal and published by Springer Science & Business Media. This book was released on 2013-05-29 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological functions and human wellbeing depend on ecosystem services. Among the ecosystem services are provisional (food, feed, fuel, fiber), regulating (carbon sequestration, waste recycling, water cleansing), cultural (aesthetic, recreational, spiritual), and supporting services (soil formation, photosynthesis, nutrient cycling). Many relationships of various degree exist among ecosystem services. Thus, land use and soil management to enhance biospheric carbon sinks for carbon sequestration requires a comprehensive understanding on the effects on ecosystem services. Payments for ecosystem services including carbon pricing must address the relationship between carbon sequestration and ecosystem services to minimize risks of overshoot, and promote sustainable use of land-based carbon sinks for human wellbeing.

Available in PDF, EPUB and Kindle. Book excerpt: Soil Health and Intensification of Agroecosystems examines the climate, environmental, and human effects on agroecosystems and how the existing paradigms must be revised in order to establish sustainable production. The increased demand for food and fuel exerts tremendous stress on all aspects of natural resources and the environment to satisfy an ever increasing world population, which includes the use of agriculture products for energy and other uses in addition to human and animal food. The book presents options for ecological systems that mimic the natural diversity of the ecosystem and can have significant effect as the world faces a rapidly changing and volatile climate. The book explores the introduction of sustainable agroecosystems that promote biodiversity, sustain soil health, and enhance food production as ways to help mitigate some of these adverse effects. New agroecosystems will help define a resilient system that can potentially absorb some of the extreme shifts in climate. Changing the existing cropping system paradigm to utilize natural system attributes by promoting biodiversity within production agricultural systems, such as the integration of polycultures, will also enhance ecological resiliency and will likely increase carbon sequestration. - Focuses on the intensification and integration of agroecosystem and soil resiliency by presenting suggested modifications of the current cropping system paradigm - Examines climate, environment, and human effects on agroecosystems - Explores in depth the wide range of intercalated soil and plant interactions as they influence soil sustainability and, in particular, soil quality - Presents options for ecological systems that mimic the natural diversity of the ecosystem and can have significant effect as the world faces a rapidly changing and volatile climate

Enzymes in the rhizosphere, in forest soils, and in volcanic ash-derived soils are described. Soil enzymes covered include phosphohydrolases, lignocellulose-degrading enzymes, phenol oxidases, fungal oxidoreductases, keratinases, pectinases, xylanases, lipases and pectinases. Several chapters treat the soil enzymatic activities in the bioremediation of soils contaminated with pesticides and pollutants such as oil, chlorinated compounds, synthetic dyes and aromatic hydrocarbons. The role of soil enzymes as bioindicators is a further important topic addressed.
Download or read book The Ecophysiology of Plant Phosphorus Interactions written by Philip J. White and published by Springer Science & Business Media. This book was released on 2008-06-03 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus (P) is an essential macronutrient for plant growth. It is as phosphate that plants take up P from the soil solution. Since little phosphate is available to plants in most soils, plants have evolved a range of mechanisms to acquire and use P efficiently – including the development of symbiotic relationships that help them access sources of phosphorus beyond the plant’s own range. At the same time, in agricultural systems, applications of inorganic phosphate fertilizers aimed at overcoming phosphate limitation are unsustainable and can cause pollution. This latest volume in Springer’s Plant Ecophysiology series takes an in-depth look at these diverse plant-phosphorus interactions in natural and agricultural environments, presenting a series of critical reviews on the current status of research. In particular, the book presents a wealth of information on the genetic and phenotypic variation in natural plant ecosystems adapted to low P availability, which could be of particular relevance to developing new crop varieties with enhanced abilities to grow under P-limiting conditions. The book provides a valuable reference material for graduates and research scientists working in the field of plant-phosphorus interactions, as well as for those working in plant breeding and sustainable agricultural development.

Download or read book Phosphorus in Action written by Else K. Bünemann and published by Springer Science & Business Media. This book was released on 2010-11-08 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus (P) is a finite resource which is essential for life. It is a limiting nutrient in many ecosystems but also a pollutant which can affect biodiversity in terrestrial ecosystems and change the ecology of water bodies. This book collects the latest information on biological processes in soil P cycling, which to date have remained much less understood than physico-chemical processes. The methods section presents spectroscopic techniques and the characterization of microbial P forms, as well as the use of tracers, molecular approaches and modeling of soil-plant systems. The section on processes deals with mycorrhizal symbioses, microbial P solubilization, soil macrofauna, phosphatase enzymes and rhizosphere processes. On the system level, P cycling is examined for grasslands, arctic and alpine soils, forest plantations, tropical forests, and dryland regions. Further, P management with respect to animal production and cropping, and the interactions between global change and P cycling, are treated.
Download or read book Agroecology in China written by Luo Shiming and published by CRC Press. This book was released on 2017-03-27 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Key features: Reviews the development of agroecology in China, including research, practice, management, and education regarding challenges for rural and agricultural progress Presents information from sources not readily available in the West about agricultural development in China during the last several decades Provides models and indicates starting points for future research and practice Addresses how to meet future challenges of agroecosystems from the field to the table in China from scientific, technological, and management perspectives During the past 30 years, industrialization has fundamentally changed traditional rural life and agricultural practices in China. While the incomes of farmers have increased, serious issues have been raised concerning the environment, resource depletion, and food safety. In response, the Chinese government and Chinese scientists encouraged eco-agriculture, the practice of agroecology principles and philosophy, as a way to reduce the negative consequences of large-scale industrialized systems of farming. Agroecology in China: Science, Practice, and Sustainable Management represents the work of experts and leaders who have taught, researched, and expanded Chinese agroecology and eco-agriculture for more than 30 years. It reviews decades of agricultural change to provide an integrated analysis of the progress of research and development in agroecological farming practices. The book contains research on traditional and newly developed agricultural systems in China, including intercropping systems, rainfall harvest systems, and rice–duck, rice–fish, and rice–frog co-culture systems. It covers current eco-agriculture practices in the major regions of China according to climate conditions. The book closes with a discussion of the major technical approaches, necessary policy support, and possible major development stages that must occur to allow broader agroecological implementations toward the sustainability of future food systems in China. Presenting eco-agriculture systems that are somewhat unique in comparison to those of the United States, Latin America, and Europe, Agroecology in China gives insight on how Chinese agroecologists, under the political and cultural systems specific to China, have created a strong foundation for ecologically sound agroecosystem design and management that can be applied and adapted to food systems elsewhere in the world. By using selected regional examinations of agroecological efforts in China as examples, this book provides models of how to conduct research on a broad range of agroecosystems found worldwide.
Download or read book Organic Crop Production Ambitions and Limitations written by Holger Kirchmann and published by Springer Science & Business Media. This book was released on 2008-12-16 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many people believe that organic agriculture is a solution for various problems related to food production. Organic agriculture is supposed to produce healthier products, does not pollute the environment, improves the fertility of soils, saves fossil fuels and enables high biodiversity. This book has been written to provide scientifically based information on organic agriculture such as crop yields, food safety, nutrient use efficiency, leaching, long-term sustainability, greenhouse gas emissions and energy aspects. A number of scientists working with questions related to organic agriculture were invited to present the most recent research and to address critical issues. An unbiased selection of literature, facts rather than standpoints, and scientifically-based examinations instead of wishful thinking will help the reader be aware of difficulties involved with organic agriculture. Organic agriculture, which originates from philosophies of nature, has often outlined key goals to reach long-term sustainability but practical solutions are lacking. The central tasks of agriculture - to produce sufficient food of high quality without harmful effects on the environment - seem to be difficult to achieve through exclusively applying organic principles ruling out many valuable possibilities and solutions.
Download or read book The Ecological Farm written by Helen Atthowe and published by Chelsea Green Publishing. This book was released on with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: The breakthrough resource for fruit and vegetable growers at every scale who want to go “beyond organic” and build higher soil quality and fertility using fewer inputs through a unique ecosystem-balancing approach. The Ecological Farm is the go-to guide for ecological growing, with a unique focus on reduced tillage, minimizing farm and garden inputs, and pest control. Reflecting the wisdom that farmer, consultant, and educator Helen Atthowe and her late husband, Carl Rosato, gained during decades of farming experience, this book guides readers on how to reduce or eliminate the use of outside inputs of fertilizer or pesticides—even those that are commonly used on certified organic orchards and market gardens. In clear language and with color photographs, charts, and graphs throughout, the book emphasizes the importance of managing the details of an entire growing system over the full life of the enterprise. Based on advances in scientific research in ecological food production, farmers, homesteaders, permaculturists, and gardeners alike will learn methods to: • design a farm system that maintains a growing root in the soil year-round to feed the microbial community instead of just crops • strengthen the “immune system” of a farm or garden • supply crop needs using only on-farm inputs such as cover crops and living mulch • maximize the presence of beneficial insects and microbes that support healthy crop development • minimize ecological impact in dealing with insect pest and disease problems This book also features a crop-by-crop guide to growing more than 25 of the most popular and profitable vegetables and fruits, including specific management advice for dealing with pests and diseases. The Ecological Farm makes complex, sometimes messy, ecological concepts and practices understandable to all growers, and makes healthy farming—in which nature is invited to participate—possible.
