DOWNLOAD EBOOK →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.

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 EBOOK →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.
