Available in PDF, EPUB and Kindle. Book excerpt: International Review of Forestry Research, Volume 1 is a collection of reviews and summaries of world literature concerning defined problem areas in forestry research. This book is composed of seven chapters, and starts with a general survey of the historical development of international forestry research, specifically in Central Europe, since the origin of forest management and of forestry as a science lies on it. This historical development includes historical methods in the practice of forest science, human influences, economics, culture, and laws. The subsequent chapters describe the methods for improvement of forest growth on swamps, the concept of nutrient requirement in forestry, and the methods for determining nutrient requirements of forest trees and stands. These topics are followed by discussions on the biological and environmental aspects of forest site appraisal systems; the anatomy, chemistry, and physiology of bark; and advances in the physiology and biochemistry of tree seeds during maturation, storage, and germination. The concluding chapter considers the development of harmonious control in agricultural, horticultural, and forestry crops, as well as the human influence on regulation and determination of insect populations. This book will prove useful to forest scientists, research workers, teachers, advanced students, administrators, economists, and forest and land managers.

Available in PDF, EPUB and Kindle. Book excerpt: Fundamental Aspects of Pollution Control and Environmental Science 1: Trace-Element Contamination of the Environment investigates the global biological consequences of dispersal of trace elements that are mined from localized limited deposits in the environment. It considers the problem of trace-element contamination of the biosphere as an environmental pollution and as part of the ecological crisis as a whole. Comprised of eight chapters, this volume begins with an overview of trace-element contaminants, such as lead, cadmium, and mercury. It then discusses factors affecting the trace-element composition of soils, including sulfur, lime, and fertilizers. It explains as well the trace-element contamination of the atmosphere and hydrosphere, the sources of trace-element contamination of soils, and the availability of trace elements in the soil. The consequences of trace-element contamination of the soil, including its effects on crops and animals, are also discussed. The book also provides ways to prevent dispersal of metals in the environment. This book will be an essential reading for undergraduates, law students, and those who are interested about environmental pollution caused by trace elements.

This book was released on 2012-12-06 with total page 759 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exactly 35 years after the first Colloquium was held, the Eleventh International Plant Nutrition Colloquium took place from 30 July to 4 August 1989 in Wageningen, The Netherlands. Although impressive progress has been made during the past decades in our understanding of the mechanisms of uptake, distribution and assimilation of nutrients in relation to crop yield and quality, there are still significant gaps in our insight into many fundamental aspects of plant mineral nutrition and related metabolic processes. In spite of improved knowledge of nutrient requirements of crops and improved fertilizer application strategies, the world population remains to be burdened with an enormous shortage of plant products for food, timber, fuel, shelter, and other purposes. The main challenge facing the plant nutrition research community is to at least alleviate the increasing world-wide need for applying scientific knowledge to practical problems in agriculture, horticulture, and forestry. It is therefore felt by many scientists that the Plant Nutrition Colloquia, which are intended to bring together scientists and to integrate knowledge and approaches acquired in plant physiology, biochemis try, soil science, agronomy and related disciplines, have indeed made a significant contribution to the advancement of our knowledge and understanding in this vital and interdisciplinary field of agrobiology. About 260 scientists from 40 nations attended the Colloquium in Wageningen.

Download or read book Plant Nutrition from Genetic Engineering to Field Practice written by J. Barrow and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 787 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Nutrition - From Genetic Engineering to Field Practice, the 12th International Colloquium on Plant Nutrition, is the latest in a series which began in 1954. Early meetings were mainly concerned with the practical problems of soil fertility, with soil assessment, fertilizer requirements and methods of analysis. As the colloquia have progressed, the emphasis has slowly changed. The practical problems are still important, but there is increasing emphasis on plant physiology, plant biochemistry, membrane biochemistry, and even on the chemistry of genes which control the proteins which transfer nutrient ions to the inside of cells. The meetings therefore provide a valuable opportunity for each half of the science of plant nutrition to interact with, and learn from the other half. This volume begins with five papers which review current knowledge in important fields: the rhizosphere, molecular biology, electron microscopy, location and function of elements in vivo, and modelling nutrient responses in the field. These themes are continued in groups of shorter papers which follow. In addition, there are sections on nutrient dynamics and partitioning, diagnostic techniques, plant survival strategies, mycorrhizas, and on nutrients such as P, N, S, K, Ca, Mg, and micronutrients. A large section is devoted specifically to boron - reflecting the considerable current interest in this element. In total there are 177 refereed papers providing both a broad overview and a detailed picture of the latest developments in pure and applied plant nutrition.

This book was released on 2012-12-06 with total page 975 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the history of the International Plant Nutrition Colloquium from its first meeting in 1954, this meeting, the 13th Colloquium, is the first to be held in Asia and will be the last in the 20th century. The 20th century has seen huge changes in the number and activities of mankind. Our population has increased from around 1. 7 billion to more than 5. 8 billion and technological innovations have completely altered our way of living. As a consequence of such rapid change, we are facing many problems including changes in our environment of a global scale. But, while food shortage has been a serious concern to mankind throughout our history, serious food shortages in the 20th century have been confined to limited times and areas. As Lester Brown discusses in this volume, farmers have increased food production heroically on demand. We, the plant nutritionists should be proud of our support to the world's farmers which has helped them make their achievement possible. During the 20th century, the science of plant nutrition also has achieved great progress as described by Jack Loneragan; it became established as a discipline firmly based in science, defined the chemical elements supporting plant growth, and has contributed to improvements in plant production and environmental quality, as readers will find in many contributions in this volume.

Download or read book Trace Element Contamination of the Environment written by D. Purves and published by Elsevier. This book was released on 2012-12-02 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is hard to imagine a more concise summary of the prodigious work and voluminous publications in this field... This volume should be available to students at the undergraduate level, to those in law school, and to all seriously concerned about an extremely important problem. This review in Choice was just one of the many favourable comments that greeted the appearance of the first edition of this book when it appeared in 1977. Since then, there has been an explosion of interest in almost every aspect of research in environmental pollution. The aim of this new edition, however, remains the same i.e. to evaluate the global biological consequences of dispersal of trace elements, originally mined from localized limited deposits, in the environment. In treating the problems of metal contamination of the environment, the author considers the problems of environmental pollution involving metals and the problem of exhaustion of finite reserves of ores of metals, such as cadmium, copper, lead, mercury, nickel and zinc, as aspects of a single global problem. A broad picture is presented of the overall process of dispersal of trace elements in the environment and the biological consequences of this process are documented with the aid of an intensive list of references. The book will be invaluable as a definitive reference source covering this field of interest for a wide range of people (environmentalists and conservationists, those concerned with management of resources and waste disposal, and agricultural chemists and soil scientists.)
