Book Description
This book examines the impact of gaseous nitrogen emissions from grasslands on atmospheric chemistry, acid rain, critical loads for ecosystems, climate change and ozone levels. The various stages of grassland production provide numerous opportunities for the escape of these environmentally active gases. These stages are examined and methods for controlling the emissions are explored. The interactions of the processes involved in the generation of these gases with other components of the overall nitrogen cycle are important and the chapters in this book look at these in terms of basic processes through to larger scale systems. The book brings together the leading workers in this area and provides an up-to-date account of the research along with implications for practice in this environmentally sensitive field. It is important reading for all grassland scientists, those involved in research into livestock production using grass and rangelands along with advisors to the farming community. It is also valuable for all those, such as ecologists and conservationists, concerned with pollution and the environment.

Book Description
Nitrous oxide gas is a long-lived relatively active greenhouse gas (GHG) with an atmospheric lifetime of approximately 120 years, and heat trapping effects about 310 times more powerful than carbon dioxide per molecule basis. It contributes about 6% of observed global warming. Nitrous oxide is not only a potent GHG, but it also plays a significant role in the depletion of stratospheric ozone. This book describes the anthropogenic sources of N2O with major emphasis on agricultural activities. It summarizes an overview of global cycling of N and the role of nitrous oxide on global warming and ozone depletion, and then focus on major source, soil borne nitrous oxide emissions. The spatial-temporal variation of soil nitrous oxide fluxes and underlying biogeochemical processes are described, as well as approaches to quantify fluxes of N2O from soils. Mitigation strategies to reduce the emissions, especially from agricultural soils, and fertilizer nitrogen sources are described in detail in the latter part of the book.

Book Description
The background This volume contains the proceedings of the first International symposium on "Non-C0 Greenhouse Gases: Why and How to 2 Control?" held in Maastricht, The Netherlands from 13-15 Decem ber 1993. Of the known greenhouse gases, political attention to date has been primarily focused on carbon dioxide (C0 ) and the 2 CFCs - the latter because of their interaction with stratospheric ozone. The other greenhouse gases, notably methane (CH ), nitrous 4 oxide (N 0), HCFCs, HFCs and tropospheric ozone and its precur 2 sors nitrogen oxides (NO), carbon monoxide (CO) and volatile organic compounds (VOCs), may appear collectively to be of equal importance for global warming but have attracted less attention. Nevertheless, a comprehensive approach to climate change respon se, taking into account all sources and sinks of all greenhouse gases, is explicitly allowed in the Framework Convention on Clima te Change. The Netherlands' policy on climate already addresses all greenhouse gases. In order to stimulate the development of international climate policy on this subject, the Dutch Ministry of Housing, Physical Planning and Environment supported the initative of organizing an international symposium on the science and policy of the non-C0 greenhouse gases. An important rationale behind 2 this initative was recognizing that for the non-C0 greenhouse 2 gases, abatement options are available that do not only address other environmental problems but that also do not require the major structural changes in society that an effective CO policy 2 may.

Book Description
Nitrous oxide is a chemical compound with the formula N2O. Despite its low concentration, nitrous oxide is the fourth largest contributor to greenhouse gases. Industrial sources make up only about 20% of all anthropogenic sources; human activity is thought to account for 30% and tropical soils and oceanic release account for 70%. This new book addresses this important environmental concern. Included is research on the soil-atmosphere exchange of N2O in managed grasslands and providing an overview of the sources of nitrogen input to grazed grasslands as well as the key soil processes regulating N2O fluxes. This book also presents new research on nitrification which also plays an important role in the removal of nitrogen from municipal wastewater.

Book Description
This study examines the interactions between nitrogen and the ecosystem and discusses nitrogen fertilization practices around the world. Simulation models that play an important role in determining the dynamics of source-sink relationships are presented, helping to pinpoint inefficiencies and develop strategies to synchronize nitrogen supply and demand.
