Download or read book Plant Respiration written by Hans Lambers and published by Springer Science & Business Media. This book was released on 2006-03-30 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Respiration in plants, as in all living organisms, is essential to provide metabolic energy and carbon skeletons for growth and maintenance. As such, respiration is an essential component of a plant’s carbon budget. Depending on species and environmental conditions, it consumes 25-75% of all the carbohydrates produced in photosynthesis – even more at extremely slow growth rates. Respiration in plants can also proceed in a manner that produces neither metabolic energy nor carbon skeletons, but heat. This type of respiration involves the cyanide-resistant, alternative oxidase; it is unique to plants, and resides in the mitochondria. The activity of this alternative pathway can be measured based on a difference in fractionation of oxygen isotopes between the cytochrome and the alternative oxidase. Heat production is important in some flowers to attract pollinators; however, the alternative oxidase also plays a major role in leaves and roots of most plants. A common thread throughout this volume is to link respiration, including alternative oxidase activity, to plant functioning in different environments.

Download or read book Principles of Agronomy for Sustainable Agriculture written by Francisco J. Villalobos and published by Springer. This book was released on 2017-01-25 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook explains the various aspects of sustainable agricultures to undergraduate and graduate students. The book first quantifies the components of the crop energy balance, i.e. the partitioning of net radiation, and their effect on the thermal environment of the canopy. The soil water balance and the quantification of its main component (evapotranspiration) are studied to determine the availability of water to rain fed crops and to calculate crop water requirements. Then it sets the limitations of crop production in relation to crop phenology, radiation interception and resource availability (e.g. nutrients). With that in mind the different agricultural techniques (sowing, tillage, irrigation, fertilization, harvest, application of pesticides, etc.) are analyzed with special emphasis in quantifying the inputs (sowing rates, fertilizer amounts, irrigation schedules, tillage plans) required for a given target yield under specific environmental conditions (soil & climate). For all techniques strategies are provided for improving the ratio productivity/resource use while ensuring sustainability. The book comes with online practical focusing on the key aspects of management in a crop rotation (collecting weather data, calculating productivity, sowing rates, irrigation programs, fertilizers rates etc).

Download or read book Plant induced soil changes Processes and feedbacks written by N. van Breemen and published by Springer Science & Business Media. This book was released on 1998-08-31 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book by soil scientists and ecologists reviews how and why plants influence soils. Topics include effects on mineral weathering, soil structure, and soil organic matter and nutrient dynamics, case studies of soil-plant interactions in specific biomes and of secondary chemicals influencing nutrient cycling, the rhizosphere, and potential evolutionary consequences of plant-induced soil changes. This is the first volume that specifically highlights the effects of plants on soils and their feedbacks to plants. By contrast, other texts on soil-plant relationships emphasize effects of soil fertility on plants, following the strongly agronomic character of most research in this area. The aspects discussed in this volume are crucial for understanding terrestrial ecosystems, biogeochemistry and soil genesis. The book is directed to terrestrial ecologists, foresters, soil scientists, environmental scientists and biogeochemists, and to students following specialist courses in these fields.
Download or read book Advances in Soil Science written by and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of Advances in Soil Science is to provide a forum for leading scientists to analyze and summarize the available scientific information on a subject, assessing its importance and identifying additional research needs. A wide array of subjects has been addressed by authors from many countries in the initial ten volumes of the series. The quick acceptance of the series by both authors and readers has been very gratifying and confirms our perception that a need did exist for a medium to fill the gap between the scientific journals and the comprehensive reference books. This volume is the first of the series devoted entirely to a single topic soil degradation. Future volumes will include both single-topic volumes as well as volumes containing reviews of different topics of soil science, as in the case of the first ten volumes. There are increasing concern and attention about managing natural re sources, particularly soil and water. Soil degradation is clearly one of the most pressing problems facing mankind. Although the spotlight regarding soil degradation in recent years has focused on Africa, concern about the degradation of soil and water resources is worldwide. The widespread con cern about global environmental change is also being linked to severe problems of soil degradation. Therefore, we are indeed pleased that the first volume of the series devoted to a single topic addresses such an impor tant issue. The current volume is also the first of the series involving a guest editor.
Download or read book Soil Physical Conditions and Plant Roots written by J. Glinski and published by CRC Press. This book was released on 2018-01-17 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a specialized monograph on soil physical conditions and root-system relations. It attempts to explain the importance of physical properties of soil by showing how they affect root growth and functions; and on the other hand, how roots themselves change their environment. Emphasis is placed on the interactive effects of soil physical factors. An attempt has been made to analyze the possibilities of the root system‘s modification by both soil and plant management.The book is addressed to research workers and advanced students in soil and plant sciences and may also be of interest to agronomists and related specialists.

Download or read book Sustainable Potato Production Global Case Studies written by Zhongqi He and published by Springer Science & Business Media. This book was released on 2012-05-24 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potato (Solanum tuberosum L.) is grown in over 100 countries throughout the world. As a staple food, potato is the fourth most important crop after rice, wheat, and maize, and has historically contributed to food and nutrition security in the world. Global interest in potato increased recently as world food prices soared, threatening the global food security and stability. Unlike major cereals, potato is not a globally traded commodity, and prices are usually determined by local production costs. Thus, potato is increasingly regarded as a vital food-security crop and as a substitute for costly cereal imports. With such importance, the 29 chapters in the edited book address the issues of sustainable potato production. This book begins with an introduction on sustainable potato production and global food security, and then presents eight case studies selected globally and covering different issues relevant to sustainable potato production in both developed and developing countries.
Download or read book Mycorrhiza written by Ajit Varma and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 703 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of Mycorrhiza falls into a time period of excep tionally rapid growth in mycorrhizal research. Therefore the edi tors have been most pleased with the decision of the Springer Verlag to revise the first edition and to incorporate the remarkable advances experienced in the mycorrhizal field. The pace of discovery has been particularly fast at the two poles of biological complexity, the molecular events leading to changes in growth and differentiation, as well as the factors regulating the structure and diversity of natural populations and communities. Therefore the most significant changes introduced in the new edition of this book are found within these topics. Not only were many chapters up dated, but also new chapters have replaced existing ones. The individual decisions have not been easy, since valuable contribu tions had to be sacrificed in favour of new aspects; but the authors hope that a highly topical new edition will be of greatest benefit for a rapidly expanding field of research. We welcome comments and critics from readers. Since it was possible again to find leading scientists as contribu tors, we are confident that this revised second edition will stimulate further progress and contribute to a deeper understanding of advances in the mycorrhizal field. We are grateful to the Springer Verlag, especially Dr. Dieter Czeschlik, for his continued interest and active help. Dr. Maja Hilber-Bodmer and Dr.
