Download or read book Progress in Nitrogen Cycling Studies written by O. van Cleemput and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the `8th Nitrogen Workshop' which was held at the University of Ghent, Belgium, from 5 to 8 September 1994. Although nitrogen dynamics in different ecosystems have been studied for several decades, new orientations and other emphases have recently emerged. Previously, nitrogen was considered as an essential element mostly in terms of productivity, but now, more emphasis is attached to environmental consequences. More than 100 contributions in this book tackle recent developments within the fields of nitrogen advice systems, plant response to fertilization, immobilization and mobilization, nitrification, denitrification, leaching, ammonia volatilization and biological nitrogen fixation. A large number of papers is devoted to the formation of gaseous nitrogen compounds, while mineralization-immobilization is another topic of important interest. The book also contains the reports of discussion groups on different aspects of the nitrogen cycle.

This book was released on 2012-12-06 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rinie Hofstra has been a member of the Department of Plant Physiology, University of Groningen, the Netherlands, for 24 years. The nearer we came to 31 March 1985, her 65th birthday, the more we all realized how we would miss her - not only scientifically, but also socially. She left her mark on both research and teaching, always with an open mind and willing to change. After her PhD Thesis on 'Nitrogen Metabolism in Tomato Plants' she first continued working in that field, but soon started a joint project with the Department of Plant Ecology on hemiparasites. She then became involved in carbon metabolism, which resulted in her giving a Biotrop Course on C /C metabolism in 3 4 Indonesia. Her own research group, originally working on 'Nitrogen Metabolism', soon embraced 'Energy and Nitrogen Metabolism', as the research on respiration became more and more important. In running her group she showed all sides of her person. She used to stimulate and encourage everyone around her and to integrate the various lines of research. At the same time she always had an open mind for the opinion of all members of her group. And together they regularly criticized and evaluated the various projects and decided how to continue.

Download or read book Mineral Nutrition of Higher Plants written by Horst Marschner and published by Elsevier. This book was released on 1995-04-11 with total page 906 pages. Available in PDF, EPUB and Kindle. Book excerpt: An understanding of the mineral nutrition of plants is of fundamental importance in both basic and applied plant sciences. The Second Edition of this book retains the aim of the first in presenting the principles of mineral nutrition in the light of current advances.This volume retains the structure of the first edition, being divided into two parts: Nutritional Physiology and Soil-Plant Relationships. In Part I, more emphasis has been placed on root-shoot interactions, stress physiology, water relations, and functions of micronutrients. In view of the worldwide increasing interest in plant-soil interactions, Part II has been considerably altered and extended, particularly on the effects of external and interal factors on root growth and chapter 15 on the root-soil interface.The second edition will be invaluable to both advanced students and researchers.Key Features* Second Edition of this established text* Structure of the book remains the same* 50% of the reference and 50% of the figures and tables have been replaced* Whole of the text has been revised* Coverage of plant (soil interactions has been increased considerably)
Download or read book Nutrient Use in Crop Production written by Zdenko Rengel and published by CRC Press. This book was released on 2017-12-14 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: If you?re an agronomist, horticulturalist, plant and soil scientist, breeder, or soil microbiologist, you?ll want to read Nutrient Use in Crop Production to find everything you need to know about judicious nutrient management and maximizing nutrient utilization in the agricultural landscape. In this book, you?ll discover ways to minimize undesirable nutrient losses and techniques for preserving the environment while meeting the challenges of providing the earth?s increasing population with sufficient food, feed, and fiber to sustain life. Your existing knowledge base concerning this vital area of science will expand and grow as you become more open to the new ideas and applications contained in Nutrient Use in Crop Production. Most importantly, you?ll avoid the narrow scope found in most crop nutrition books and take a broader, more globally minded view of how to maximize nutrient use and minimize nutrient losses in the soil of agricultural systems. Specifically, you?ll find these and other areas covered: population growth, food production, and nutrient requirements managing soil fertility decline the role of nitrogen fixation in crop production delivering fertilizers through seed coatings micronutrient fertilizers the role of nutrient-efficient crops in modern agriculture Feeding the world without depleting the world?s viable soil nutrients is a monumental task--but one that can be achieved, as evidenced in the pages of Nutrient Use in Crop Production. You and your circle of students, professionals, and administrators will benefit greatly from this in-depth view of nutrient use in both developed and non-industrialized counties to give you a better sense of how to allow both the world and the world?s crops to grow.

Download or read book Marschner s Mineral Nutrition of Higher Plants written by Horst Marschner and published by Academic Press. This book was released on 2011-08-25 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Respected and known worldwide in the field for his research in plant nutrition, Dr. Horst Marschner authored two editions of Mineral Nutrition of Higher Plants. His research greatly advanced the understanding of plant nutrition ranging from rhizosphere processes to nutrient uptake and utilization by plants in the field. While visiting field experiments in West Africa in 1996, Dr. Marschner contracted malaria and passed away, and until now this legacy title went unrevised. Despite the passage of time, it remains the definitive reference on plant mineral nutrition. Since the last edition, great progress has been made in the understanding of various aspects of plant nutrition. In recent years, the perspective on the mode of action of nutrients in plant metabolism and yield formation has shifted. Much progress has been made in the molecular aspects of nutrient uptake and transport within plants as well as the responses of plants to nutrient deficiency or toxicity. These and many other developments are covered in this long-awaited new edition."--P. [4] of cover.
