Book Description
Soil acidity is a major limitation to crop production in many parts of the world. Plant growth inhibition results from a combination of factors, including aluminum, manganese, and hydrogen ion toxicities and deficiencies of essential elements, particularly calcium, magnesium, phosphorus, and molybdenum. Agricultural management practices and acid precipitation have increased acid inputs into the ecosystem and heightened concern about soil acidity problems. While application of lime has proved to be effective in ameliorating surface soil acidity in many areas, significant soil acidity problems still exist. Scientists from Alberta, Canada, recognized the need to provide a forum for researchers from different disciplines to exchange information and ideas on solving problems of plant growth in acid soils. As a result of their efforts, the First International Symposium on Plant-Soil Interactions at Low pH was held at Grande Prairie, Alberta, Canada, in July 1987. In many acid soil areas, liming materials are not readily available, the cost may be prohibitive, or subsoil acidity cannot be corrected by surface application of lime. New management approaches involving both the plant and the soil are needed in these situations. Progress has been made in the selection and breeding of acid-tolerant plants. However, continued progress will be limited by our lack of understanding of the physiological and biochemical basis of differential acidity tolerance among plants.

Book Description
The area of native prairie known as the Great Plains once extended from Canada to the Mexican border and from the foothills of the Rocky Mountains to western Indiana and Wisconsin. Today the declines in prairie landscape types, estimated to be as high as 99%, exceed those of any other major ecosystem in North America. The overwhelming loss of landscape and accompanying loss of species constitute a real threat to both ecological and human economic health.Prairie Conservation is a comprehensive examination of the history, ecology, and current status of North American grasslands. It presents for the first time in a single volume information on the historical, economic, and cultural significance of prairies, their natural history and ecology, threats, and conservation and restoration programs currently underway. Chapters cover: environmental history of the Great Plains the economic value of prairie prairie types -- tallgrass, mixed grass, shortgrass, wetlands -- and the ecological processes that sustain each type prairie fauna -- invertebrates, fish and other aquatic creatures, amphibians and reptiles, birds, and mammals conservation programs such as the Great Plains Partnership, Canada's Prairie Conservation Action Plan, the U.S. Prairie Pothole Joint Venture, and others The book brings together knowledge and insights from a wide range of experts to describe and explain the importance of prairies and to position them in the forefront of North American conservation efforts. Praire Conservation is an essential reference for anyone interested in prairie ecology and conservation and will play a critical role in broadening our awareness and understanding of prairie ecosystems.

Book Description
Soil Acidity and Plant Growth emerged from concerns over increasing acidification of soils under improved pastures over wide areas of southern Australia. While the book has its origin in the problems of acidification of Australian soils under pastures, the authors examine soil acidity within a much broader framework, making their views relevant to all agricultural and natural ecosystems on acid soils. The book's first two chapters discuss the chemistry of soil acidity and the ecological processes leading to it. This is followed by separate chapters on biological responses to soil acidity, covering mineralization of soil nitrogen, incidence of plant diseases, plant mycorrhizal associations, symbiotic nitrogen fixation in legumes, and genetic variability in plant response to toxicities. The remaining chapters focus on the correction of soil acidity problems by liming. These include studies on the rates of application and effectiveness of liming materials; and the development and use of computer modelling procedures to help researchers identify the effects and interactions of soil pH on component processes and to provide assistance to farmers in the management of long-term subterranean clover pastures.

Book Description
Fire and Ecosystems focuses on a number of aspects of fire ecology. This book deals separately with both harmful and beneficial effects of fire on soils, soil organisms, animals, and plants. This reference material elucidates the effects of fire on grasslands and considers the role of fire in temperate forests and related ecosystems. Four chapters are presented on a regional basis to highlight variations in responses, especially plant succession, to fire. The use of fire in land management is also explored. This book will serve as an invaluable reference material to researchers, teachers, and land managers.
