Download or read book Nitrogen fixing Actinorhizal Symbioses written by Katharina Pawlowski and published by Springer Science & Business Media. This book was released on 2007-10-06 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: For researchers and graduates with any interest in plant or soil sciences, this fascinating study will be a godsend – it’s the complete state of the art with regard to actinorhizal symbioses. The self-contained sixth volume of a comprehensive series on nitrogen fixation, it includes chapters that deal with all aspects of this symbiosis between actinorhizal plants and nitrogen-fixing bacteria. It also contains information both about symbionts and their ecological role and use. Other chapters tackle the global distribution of different actinorhizal plants and their microsymbionts and how this impacts the question of co-evolution of the micro- and macrosymbionts as well as comparing the actinorhizal and leguminous symbioses. No other book provides the up-to-date and in-depth coverage of this volume.

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 2006-01-20 with total page 361 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 Biological Nitrogen Fixation for Sustainable Agriculture written by J.K. Ladha and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical fertilizers have had a significant impact on food production in the recent past, and are today an indispensable part of modern agriculture. On the other hand, the oil crisis of the 1970s and the current Middle East problems are constant reminders of the vulnerability of our fossil fuel dependent agriculture. There are vast areas of the developing world where N fertilizers are neither available nor affordable and, in most of these countries, balance of payment problems have resulted in the removal of N fertilizer subsidies. The external costs of environmental degradation and human health far exceed economic concerns. Input efficiency of N fertilizer is one of the lowest and, in turn, contributes substantially to environmental pollution. Nitrate in ground and surface waters and the threat to the stability of the ozone layer from gaseous oxides of nitrogen are major health and environmental concerns. The removal of large quantities of crop produce from the land also depletes soil of its native N reserves. Another concern is the decline in crop yields under continuous use of N fertilizers. These economic, environmental and production considerations dictate that biological alternatives which can augment, and in some cases replace, N fertilizers must be exploited. Long-term sustainability of agricultural systems must rely on the use and effective management of internal resources. The process of biological nitrogen fixation offers and economically attractive and ecologically sound means of reducing external nitrogen input and improving the quality and quantity of internal resources. In this book, we outline sustainability issues that dictate an increased use of biological nitrogen fixation and the constraints on its optimal use in agriculture.
Download or read book Handbook of Bioenergy Crop Plants written by Chittaranjan Kole and published by CRC Press. This book was released on 2012-03-22 with total page 876 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the world’s population is projected to reach 10 billion or more by 2100, devastating fossil fuel shortages loom in the future unless more renewable alternatives to energy are developed. Bioenergy, in the form of cellulosic biomass, starch, sugar, and oils from crop plants, has emerged as one of the cheaper, cleaner, and environmentally sustainable alternatives to traditional forms of energy. Handbook of Bioenergy Crop Plants brings together the work of a panel of global experts who survey the possibilities and challenges involved in biofuel production in the twenty-first century. Section One explores the genetic improvement of bioenergy crops, ecological issues and biodiversity, feedstock logistics and enzymatic cell wall degradation to produce biofuels, and process technologies of liquid transportation fuels production. It also reviews international standards for fuel quality, unique issues of biofuel-powered engines, life-cycle environmental impacts of biofuels compared with fossil fuels, and social concerns. Section Two examines commercialized bioenergy crops, including cassava, Jatropha, forest trees, maize, oil palm, oilseed Brassicas, sorghum, soybean, sugarcane, and switchgrass. Section Three profiles emerging crops such as Brachypodium, diesel trees, minor oilseeds, lower plants, Paulownia, shrub willow, sugarbeet, sunflower, and sweet potato. It also discusses unconventional biomass resources such as vegetable oils, organic waste, and municipal sludge. Highlighting the special requirements, major achievements, and unresolved concerns in bioenergy production from crop plants, the book is destined to lead to future discoveries related to the use of plants for bioenergy production. It will assist in developing innovative ways of ameliorating energy problems on the horizon.
