Download or read book Nitrogen Economy in Tropical Soils written by N. Ahmad and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen Economy in Tropical Soils presents an authoritative and comprehensive state-of-the-art review on soil/plant nitrogen inter-relationships, with special reference to tropical soils and crops in aerobic and anaerobic environments. Use of isotopically labelled nitrogen in experimentation, especially in tropical environments, and recently developed analytical techniques for soil and plant materials are presented. An important aspect is the emphasis placed on the impact of the tropical environment on nitrogen transformations in the soil environment. This book should be an excellent source of information for senior undergraduate and graduate students with interest in soil/plant nitrogen inter-relationships, and for all levels of research workers in these fields.

Download or read book Proceedings of Symposium on Paddy Soils written by Institute of Soil Science, Academia Sinica and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 876 pages. Available in PDF, EPUB and Kindle. Book excerpt: China contributes a large part to rice production, one of the most important crops in the world. It is estimated that in China rice constitutes about half of the total food production, covering an area of about 30 % of \08 hectares of cultivated land of the whole country. Owing to the peculiar water regime, paddy soils possess quite different properties physically, chemically and biologically as compared with those of upland soils. Such properties have a conspicuous effect on fertility and management practice of paddy field. For the purpose of summing up the past work and opening up new prospects, a "Symposium on Paddy Soils" was organized under the auspices of Academia Sinica, held on October 19-24, 1980 in Nanjing, which was followed by a seven-day paddy soil excursion in the lower Changjiang Delta. In addition to 120 Chinese soil scientists, 56 guests coming from America, Asia, Europe and Oceania attended the symposium on invitation. A total of 110 papers were presented either orally or by poster. All these are collected and published in the present proceedings which we hope may be helpful to the scientific exchanges between soil scientists of China and other countries.

Download or read book Asia Pacific Symposium on Mangrove Ecosystems written by Yuk-Shan Wong and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mangrove ecosystems are typical formations found in coastal deposits of mud and silt throughout the tropics and some distance into the subtropical latitudes. The total wordwide mangrove area, which is estimated at about 170,000 km2 with some sixty species of trees and shrubs exclusive to the habitat, dominates approximately 75% of the world's coastline between latitudes 25°N and 25°S. Such unique intertidal ecosystems support genetically diverse communities of terrestrial and aquatic organisms that are of direct or indirect socioeconomic values. Mangrove forests play important roles as coastal stabilization and protection against winds and storms; producers of nutrients, forest resources and animal species of economic importance. Recently, the issues on the conservation, proper utilization and management of mangrove forests have been widely discussed. Unfortunately, overexploitation and destruction of mangroves seriously threatens the sustainability of such a unique ecosystem. This volume includes papers on three main areas: recent advances in mangrove ecology; application and utilization of mangrove resources; and conservation and management of the ecosystems.

Download or read book Processes of Vegetation Change written by Colin Burrows and published by Springer Science & Business. This book was released on 1990-10-11 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covering ideas on the nature and causes of temporal change in the species composition of vegetation, this book examines in particular the diverse processes of interaction of plants with their environment and with one another, through which the species composition of vegetation becomes established. Areas covered range from the tropics to sub-polar regions and from sea shores, through deserts, grasslands and forests to alpine regions. The text focuses on the nature of reciprocal interaction between plants and their habitats and other organisms; outlines events that occur during the colonization of new sites and consequent modifications of habitat; explores long-term consequences of change, using chrono-sequences and fossil data from wetland sites; and considers cyclical replacement sequences, direct replacements and fluctuations in the context of short-term and long-term change.
Download or read book Principles and Practices in Plant Ecology written by Inderjit and published by CRC Press. This book was released on 2023-07-21 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: Principles and Practices in Plant Ecology: Allelochemical Interactions provides insights and details recent progress about allelochemical research from the ecosystem standpoint. Research on chemical ecology of allelochemicals in the last three decades has established this field as a mature science that interrelates the research of biologists, weed and crop scientists, agronomists, natural product chemists, microbiologists, ecologists, soil scientists, and plant physiologists and pathologists. This book demonstrates how the influence of allelochemicals on the various components of an ecosystem-including soil microbial ecology, soil nutrients, and physical, chemical, and biological soil factors-may affect growth, distribution, and survival of plant species. Internationally renowned exper†s discuss how a better understanding of allelochemical phenomena can lead to true sustainable agriculture.

Download or read book Plant Soil Interactions at Low pH written by Robert J. Wright and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1057 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
