Download or read book Mixed Plantations of Eucalyptus and Leguminous Trees written by Elke Jurandy Bran Nogueira Cardoso and published by Springer Nature. This book was released on 2020-03-19 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to present, in depth, updated information on soil and microbial processes involved in mixed plantations of Eucalyptus and N2-fixing species, especially Acacia mangium, focusing on Forestry, Soils, Biology, Ecosystem Services and Sustainability. The potential of substituting chemical N fertilizer by a consortium of leguminous species that fix atmospheric nitrogen is an interesting solution for a more sustainable, economically and environmentally sound forest system. Among the main topics, we present reference topics on soil microbiology, as biological nitrogen fixation, the role of mycorrhiza in mixed plantations, bio-indicators of soil quality, and plantgrowth promoting bacteria with biotechnological potential. Here we discuss Ecosystem services and ecological benefits of these systems, the invasive potential of A.mangium, as well as the regulations and perspectives of land use policies for mixed forests and their role in the sustainability of the system.
Download or read book Nitrogen Fixation in Agriculture Forestry Ecology and the Environment written by Dietrich Werner and published by Springer Science & Business Media. This book was released on 2005-10-24 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainability has a major part to play in the global challenge of continued development of regions, countries, and continents all around the World and biological nitrogen fixation has a key role in this process. This volume begins with chapters specifically addressing crops of major global importance, such as soybeans, rice, and sugar cane. It continues with a second important focus, agroforestry, and describes the use and promise of both legume trees with their rhizobial symbionts and other nitrogen-fixing trees with their actinorhizal colonization. An over-arching theme of all chapters is the interaction of the plants and trees with microbes and this theme allows other aspects of soil microbiology, such as interactions with arbuscular mycorrhizal fungi and the impact of soil-stress factors on biological nitrogen fixation, to be addressed. Furthermore, a link to basic science occurs through the inclusion of chapters describing the biogeochemically important nitrogen cycle and its key relationships among nitrogen fixation, nitrification, and denitrification. The volume then provides an up-to-date view of the production of microbial inocula, especially those for legume crops.

Download or read book Nitrogen in Agriculture written by Khan Amanullah and published by BoD – Books on Demand. This book was released on 2018-02-01 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is the most yield-restraining nutrient in crop production globally. Efficient nitrogen management is one of the most important factor for improving nitrogen use efficiency, field crops productivity and profitability. Efficient use of nitrogen for crop production is therefore very important for increasing grain yield, maximizing economic return and minimizing nitrous oxide (N2O) emission from the fields and nitrate (NO3) leaching to ground water. Integrated nitrogen management is a good strategy to improve plant growth, increase yield and yield components, grain quality and reduce environmental problems. Integrated nitrogen management (combined use of chemical + organic + bio-fertilizers) in field crop production is more resilient to climate change.
Download or read book Advances in Biology and Ecology of Nitrogen Fixation written by Takuji Ohyama and published by BoD – Books on Demand. This book was released on 2014-01-29 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological nitrogen fixation has essential role in N cycle in global ecosystem. Several types of nitrogen fixing bacteria are recognized: the free-living bacteria in soil or water; symbiotic bacteria making root nodules in legumes or non-legumes; associative nitrogen fixing bacteria that resides outside the plant roots and provides fixed nitrogen to the plants; endophytic nitrogen fixing bacteria living in the roots, stems and leaves of plants. In this book there are 11 chapters related to biological nitrogen fixation, regulation of legume-rhizobium symbiosis, and agriculture and ecology of biological nitrogen fixation, including new models for autoregulation of nodulation in legumes, endophytic nitrogen fixation in sugarcane or forest trees, etc. Hopefully, this book will contribute to biological, ecological, and agricultural sciences.
Download or read book Ecology and Management of Forest Soils written by Dan Binkley and published by John Wiley & Sons. This book was released on 2012-11-05 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest soils are the foundation of the entire forest ecosystem and complex, long-term interactions between trees, soil animals, and the microbial community shape soils in was that are very distinct from agricultural soils. The composition, structure, and processes in forest soils at any given time reflect current conditions, as well as the legacies of decades (and even millennia) of interactions that shape each forest soil. Reciprocal interactions are fundamental; vegetation alters soil physical properties, which influence soil biology and chemistry, which in turn influence the growth and success of plants. These dynamic systems may be strongly influenced by intentional and unintentional management, ranging from fire to fertilization. Sustaining the long-term fertility of forest soils depends on insights about a diverse array of soil features and changes over space and time. Since the third edition of this successful book many new interests in forest soils and their management have arisen, including the role of forest soils in sequestering carbon, and how management influences rates of carbon accumulation. This edition also expands the consideration of how soils are sampled and characterized, and how tree species differ in their influence on soil development. Clearly structured throughout, the book opens with the origins of forest soil science and ends with the application of soil science principles to land management. This new edition provides: A completely revised and updated Fourth Edition of this classic textbook in the field A coherent overview of the major issues surrounding the ecology and management of forest soils Global in scope with coverage of soil types ranging from the tropical rainforest soils of Latin America to the boreal forest soils of Siberia New chapters on Management: Carbon sequestration; Evidence-based approaches and applications of geostatistics, GIS and taxonomies A clear overview of each topic, informative examples/case studies, and an overall context for helping readers think clearly about forest soils An introduction to the literature of forest soil science and to the philosophy of forest soil science research This coherent overview of the major issues surrounding the ecology and management of forest soils will be particularly useful to students taking courses in soil science, forestry, agronomy, ecology, natural resource management, environmental management and conservation, as well as professionals in forestry dealing with the productivity of forests and functioning of watersheds.

Available in PDF, EPUB and Kindle. Book excerpt: Permaculture is a movement that is coming into its own, and the concept of creating plant guilds in permaculture is at the forefront of every farmer's and gardener's practice. One of the essential practices of permaculture is to develop perennial agricultural systems that thrive over several decades without expensive and harmful inputs: perennial plant guilds, food forests, agroforestry, and mixed animal and woody species polycultures. The massive degradation of conventional agriculture and the environmental havoc it creates has never been as all pervasive in terms of scale, so it has become a global necessity to further the understanding of a comprehensive design and planning system such as permaculture that works with nature, not against it. The guild concept often used is one of a "functional relationship" between plants-beneficial groupings of plants that share functions in order to bring health and stability to a plant regime and create an abundant yield for our utilization. In other words, it is the integration of species that creates a balanced, healthy, and thriving ecosystem. But it goes beyond integration. A guild is a metaphor for all walks of life, most importantly a group of people working together to craft works of balance, beauty, and utility. This book is the first, and most comprehensive, guide about plant guilds ever written, and covers in detail both what guilds are and how to design and construct them, complete with extensive color photography and design illustrations. Included is information on: - What we can observe about natural plant guilds in the wild and the importance of observation; - Detailed research on the structure of plant guilds, and a portrait of an oak tree (a guild unto itself); - Animal interactions with plant guilds; - Steps to guild design, construction, and dynamics: from assessment to design to implementation; - Fifteen detailed plant guilds, five each from the three authors based on their unique perspectives; - Guild project management: budgets, implementation, management, and maintenance. Readers of any scale will benefit from this book, from permaculture designers and professional growers, to backyard growers new to the concept of permaculture. Books on permaculture cover this topic, but never in enough depth to be replicable in a serious way. Finally, it's here!
