`The fundamental problem the world faces today, is the rapidly increasing pressure of population on the limited resources of the land. To meet the ever increasing demands of expanding populations, agricultural production has been raised through the abundant use of inorganic fertilizers, the adoption of multicropping systems and liberal application of chemical pesticides (fungicides, bactericides, etc. ). Though the use of chemicals has increased the yield dramatically, it has also resulted in the rapid deterioration of land and water resources apart from wastage of scarce resources. This has adversely affected the biological balance and lead to the presence of toxic residues in food, soil and water in addition to imposing economic constraints on developing countries.' (From the Preface) Mycorrhizal Biology addresses the global problem of land degradation and the associated loss of soil productivity and decline in soil quality caused by exploitative farming practices and poor management in developing countries, and the far reaching socio-economic and ecological consequences of its impact on agricultural productivity and the environment. In the light of a need for sustainable development, a new system of productive agriculture, to ensure the efficient management of agricultural inputs for long term high crop productivity with minimum damage to the ecological and socio-economic environment is essential. The management of mycorrhizal fungi will form a significant part of such a system and this work investigates the key association of plant roots with mycorrhizal fungi, known to benefit plants under conditions of nutritional and water stress and pathogen challenge and analyses the developments in our understanding of the genetic loci that govern mycorrhiza formation.

Scientists, within a wide field, ranging from applied forestry and agriculture to physiology, ecology and the environmental sciences, are today more than ever involved in root and mycorrhizal research. New problem-oriented research fields have arisen such as the effects of fertilizers and pesticides, forest management and regeneration etc. At a time when root research is expanding into different areas, it is much more difficult for the root scientist to penetrate all the new information appearing in literature. The contributors of this volume are leading scientists from different fields of root research. The ISRR-symposium in Uppsala clearly demonstrated that there are new techniques in progress, in particular with regards to video recording of plant root systems and digital image processing. The main objectives of the symposium were (i) to provide a forum for communication between scientists from different disciplines working with root research problems, (ii) to contribute to an expansion of root studies into new areas, (iii) to use current estimates of root turnover for charting the upper and lower limit of below-ground production, and (iv) to spread knowledge of new findings and techniques of the importance of root research. This book is aimed at serving as a vehicle for improving the coherence of root research, for harmonizing methods and establishing overall objectives and gaps in the knowledge of rhizosphere dynamics.

Conifer Seedling Mineral Nutrition provides a comprehensive review of conifer seedling mineral nutrition and its significance to forestry. The book covers relationships between mineral supply and uptake; the effects of nutrition on seedling growth; an integration of the ideas of T. Ingestad with classical growth analysis concepts; practical aspects of assessing nutrient status and details of fertilizing bare root and container nursery stock; and fertilizing vegetative propagules. The book also describes and illustrates Mycorrhizas, assessing their importance to plantation establishment in an analysis of recent papers reporting field trials. The effects of nutrients on stress resistance and establishment when applied in the nursery and while planting are discussed in the final chapter. It will prove useful to reforestation research workers, nurserymen, and silviculturalists and should be considered essential reading for forestry students.

This college-level textbook summarizes the state of current knowledge in the rapidly expanding field of agroforestry. The book, organized into 25 chapters in six sections, reviews the developments in agroforestry during the past 15 years and describes the accomplishments in the application of biophysical (plant and soil related) and socioeconomic sciences to agroforestry. Although the major focus of the book is on the tropics, where the practice and potential of agroforestry are particularly promising, the developments in temperate zone agroforestry are also discussed. This text is recommended for students, teachers, and researchers in agroforestry, farming systems, and tropical land use.

We live in a well-engineered universe. This engineering is present in every system and organism in existence, including in the actions and interactions of plants and animals. In fact, one could say that the function and movement of plants and animals is just as much a part of their makeup as chlorophyll and fiber or bone and blood. Consequently, if we want to understand the ecology of animals and plants especially in an integrated ecosystem, it follows that great insight can be gained by taking an approach that studies function and integration of parts rather than the individual parts themselves. Ecology and Biomechanics: A Mechanical Approach to the Ecology of Animals and Plants offers a collection of state-of-the-art papers that ingeniously demonstrates how biomechanics can provide novel insights into long standing ecological and evolutionary questions. The majority of the book's chapters were originally presented at a symposium held at the annual meeting of the Society for Experimental Biology in Edinburgh, U.K., in 2004. Combining approaches from various disciplines, this volume covers subjects that encompass theoretical concepts and practical approaches involving research on both plants and animals, as well as interactions between the two. Although most of the examples emphasize distinct organism-environment relationships such as the grazing of ruminants, the book also includes a few examples that span larger temporal and spatial scales, achieving wider application across ecosystems. This can be seen in the chapter Implications of Microbial Motility on the Water Column Ecosystems, which highlights how microbial ecosystems can be understood from the mechanics, morphology, and motile responses of the individual organisms. Designed to serve as a reference for students and researchers, Ecology and Biomechanics: A Mechanical Approach to the Ecology of Animals and Plants paves the way for further research by demonstrating what can happen when the approaches from two seemingly disparate subdisciplines within the field of biology are creatively combined.

Global agriculture is now at the crossroads. The Green Revolution of the last century is losing momentum. Rates of growth in food production are now declining, with land and water resources becoming scarcer, while world population continues to grow. We need to continue to identify and share the knowledge that will support successful and sustainable agriculture systems. These depend crucially on soil. Gaining international attention, Dr. Uphoff’s efforts to promote and develop sustainable agriculture was recently featured in the N.Y. Times Led by Norman Uphoff, internationally renowned for his proactive approach to world hunger, this volume brings together 102 experts representing 28 nations and multiple disciplines to report on achievements in sustainable soil-system management. While accepting some continuing role for chemical and other external inputs, this book presents ways in which crops can be produced cost effectively in greater abundance with lessened dependence on the exogenous resources that have driven the expansion of agriculture in the past. Including the work of both researchers and practitioners, this important volume — · Explores soil systems in a variety of climate conditions · Discusses the importance of symbiotic relationships between plants and soil organisms, looking at crops as integral and interdependent participants in ecosystems · Seeks to reduce the distance between scientific research and technical practice · Examines related considerations such as pest and disease control, climate change, fertility restoration, and uses of monitoring and modeling With 50 self-contained chapters, this work provides researchers, practitioners, and policy makers with a comprehensive understanding of the science and steps needed to utilize soil systems for the long-term benefit of humankind.
