ISBN-13: 0323138233
DOWNLOAD EBOOKWater Relations of Plants attempts to explain the importance of water through a description of the factors that control the plant water balance and how they affect the physiological processes that determine the quantity and quality of growth. Organized into 13 chapters, this book first discusses the functions and properties of water and the plant cell water relations. Subsequent chapters focus on measurement and control of soil water, as well as growth and functions of root. This book also looks into the water absorption, the ascent of sap, the transpiration, and the water stress and its effects on plant processes and growth. This book will be useful for students, teachers, and investigators in both basic and applied plant science, as well as for botanists, agronomists, foresters, horticulturists, soil scientists, and even laymen with an interest in plant water relations.
Gaseous Loss of Nitrogen from Plant-Soil Systems

ISBN-13: 9401716625
DOWNLOAD EBOOKA growing interest has been shown recently in the dymanics of nitrogen in agricultural and natural ecosystems. This has been caused by increasing demands for food and fibre by a rapidly expanding world population, and by a growing concern that increased land clearing, cultivation and use of both fertilizer and biologically fixed nitrogen can have detrimental effects on the environment. These include effects on water quality, eutrophication of surface waters and changes in atmospheric composition all caused by increased cycling of nitrogenous compounds. The input and availability of nitrogen frequently affects the productivity of farming systems more than any other single management factor, but often the nitrogen is used inefficiently. Much of the fertilizer nitrogen applied to the soil is not utilised by the crop: it is lost either in solution form, by leaching of nitrate, or in gaseous forms as ammonia, nitrous oxide, nitric oxide or dinitrogen. The leached nitrate can contaminate rivers and ground waters, while the emitted ammonia can contaminate surface waters or combine with atmospheric sulfur dioxide to form aerosols which affect visibility, health and climate. There is also concern that increased evolution of nitrous oxide will deplete the protective ozone layer of the stratosphere. The possibility of a link between the intensity of agricultural use of nitrogen, nitrous oxide emissions and amounts of stratospheric ozone has focussed attention on these interactions.

DOWNLOAD EBOOKAdvances in Microbial Ecology was established by the International Committee on Microbial Ecology (ICOME) to provide a vehicle for in-depth, critical, and even provocative reviews to emphasize recent trends in the important field of microbial ecology. Advances in Microbial Ecology is now recognized as a major source of infor mation and inspiration both for practicing and for prospective microbial ecologists. Most reviews appearing in Advances have been prepared by leaders in particular areas follow ing invitations issued by the Editorial Board. Individuals are encouraged, however, to submit outlines of unsolicited contributions to any member of the Editorial Board for consideration for publication in Advances. With the publication of Volume 12 of Advances in Microbial Ecology there will be a change of Editor and the entire Editorial Board. The current Editor wishes to take this opportunity to thank the present Editorial Board, Ron Atlas, Bo Barker J~rgensen, and Gwyn Jones, as well as past members of the Board, for their assistance and encourage ment over the years. The new Editor of Advances in Microbial Ecology will be Gwyn Jones, with Bernhard Schink, Warwick F. Vincent, and David M. Ward as members of the Editorial Board. The outgoing Board wish the new Board every success in continu ing the traditions established by Martin Alexander, the founding Editor of Advances in Microbial Ecology. The topics featured in Volume 12 of Advances include some related to the meta bolic activities of bacteria; namely, bioremediation of oil spills, by R. M. Atlas and R.
SEBS 30 Root Development and Function

ISBN-13: 9780521329316
DOWNLOAD EBOOKFirst published in 1987 this book looks at root development and functions. Besides affecting the development of roots directly, the physical environment also influences the organisms associated with roots and thus affects their function. The papers presented in this volume pay equal attention to root development and root function in relation to the whole range of environmental factors including temperature, light, water, aeration, gravity and the mechanical strength of the soil. Consideration is also given to the effects of some of these factors on mycorrhizae and nitrogen-fixing bacteria. The final chapter reviews some of the main themes raised in the volume and indicates the way that research at the cellular and tissue levels may progress in the future.
