Book Description
Plants take up only 50 percent of the nitrogen fertilizer applied to agricultural land. Part of this inefficiency is a result of emissions of ammonia (NH3 ), nitrous oxide (N2O) and nitric oxide (NO). Quantifying these emisions is important, both as part of an attempt to improve fertilizer use efficiency and because of their influence on ecosystems, atmospheric pollution and the so-called greenhouse effect. This report provides a comprehensive review of the literature about emissions of NH3, N2O and NO, and examines the regulating factors, measurement techniques and models. It draws these data together and generates global emission estimates that can serve as a basis for further addressing the issues of efficiency and environmental impact.

Book Description
A rapidly changing and expanding livestock and poultry production sector is causing a range of environmental problems on local, regional and global scales. Animal Manure Recycling: Treatment and Management presents an accessible overview of environmentally friendly technologies for managing animal manure more efficiently and in a sustainable manner. The book describes the physical and chemical characteristics of animal manure and microbial processes, featuring detailed examples and case studies showing how this knowledge can be used in practice. Readers are introduced to the sustainable use of animal manure for crop fertilisation and soil amelioration. Environmentally friendly technologies for reducing emissions of ammonia, odour and the greenhouse gases nitrous oxide and methane are presented, and reduction of plant nutrient losses using separation technologies is introduced. Finally and most importantly, the book describes methods to commercialise and transfer knowledge about innovations to end-users. Topics covered include: Regulation of animal manure management Manure organic matter: characteristics and microbial transformations Greenhouse gas emissions from animal manures and technologies for their reduction Technologies and logistics for handling, transport and distribution of animal manures Bioenergy production Animal manure residue upgrading and nutrient recovery in bio-fertilisers Life cycle assessment of manure management systems Innovation in animal manure management and recycling Animal Manure Recycling: Treatment and Management presents state-of-the-art coverage of the entire animal manure chain, providing practical information for engineers, environmental consultants, academics and advanced students involved in scientific, technical and regulatory issues related to animal manure management.

Book Description
"Soil nitrous oxide (N2O) emission varies in magnitude and occurs sporadically during the spring freeze-thaw period in cold humid temperate regions. Fluctuations in soil N2O emissions are related to soil biophysical properties, which are influenced by agricultural practices like fall application of manure and fall-sown cover crops, as well as rainfall and other weather events. The objectives of this thesis were to (1) quantify N2O emissions in the spring period from agricultural soils that received manure and were planted with a cover crop in the previous fall, (2) estimate the influence of fall-applied manure and cover crops on the spring soil N2O emissions in changing climate, (3) determine the biophysical factors that control soil N¬2O emissions after a rain-induced thawing event, and (4) propose a monitoring method to estimate N2O emissions in agricultural soils. First, I quantified the soil N2O emissions with a two-year field experiment. Soil N2O emission in the spring freeze-thaw period (c.a. 30 d) was -2.35 to 13.57 g N ha-1 and not affected by dairy manure application (solid or liquid) or cover crops (ryegrass and ryegrass/hairy vetch), possibly due to the low manure N application rate and N loss over winter. Second, I evaluated soil N2O emissions in the spring freeze-thaw period under three climate scenarios (baseline, from 1981–2010; Representative Concentration Pathway 4.5 and 8.5 from 2071–2100) with the Decomposition-Denitrification model. The model predicted that more reactive N will be retained by cover crops under future climate scenarios, but the soil N2O emissions will not increase. However, applying solid manure without a cover crop led to more soil N2O emissions than other treatments tested under three climate scenarios (9.90 to 61.50 g N ha-1, P

Book Description
Carbon and Nitrogen in the Terrestrial Environment is a comprehensive, interdisciplinary description of C and N fluxes between the atmosphere and the terrestrial biosphere; issues related to C and N management in different ecosystems and their implications for the environment and global climate change; and the approaches to mitigate emission of greenhouse gases. Drawing upon the most up-to-date books, journals, bulletins, reports, symposia proceedings and internet sources documenting interrelationships between different aspects of C and N cycling in the terrestrial environment, Carbon and Nitrogen in the Terrestrial Environment fills the gap left by most of the currently available books on C and N cycling. They either deal with a single element of an ecosystem, or are related to one or a few selected aspects like soil organic matter (SOM) and agricultural or forest management, emission of greenhouse gases, global climate change or modeling of SOM dynamics.

Book Description
Traditionally, livestock manure has been used to provide nutrients for plant growth and to improve soil conditions. However, the increase in concentrated animal feeding operations (CAFOs) results in high levels of plant nutrients, such as nitrogen and phosphorus, in the proximal crop and pasturelands as a result of applying more manure than what is required to meet the local plant nutrient demand. Soil runoff and leaching of land-applied manure can enrich the surface and ground water with nitrogen and phosphorus, leading to eutrophication and hypoxia. In addition, overapplication of animal manure contributes to pathogen spread, the release of hormones and other pharmaceutically active compounds, and the emission of ammonia, greenhouse gases, and odorous compounds. In this Special Issue, we present 11 interesting articles covering the production of renewable energy and fuels, extraction of ammonia from animal manure, the agricultural and environmental benefits of using animal manure or its derived materials such as biochar or ashes, and the difference in microbial communities and pathogen survival after anaerobic lagoon treatment.

Book Description
This open access book is an outcome of the collaboration between the Soil and Water Management & Crop Nutrition Section, Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, Department of Nuclear Sciences and Applications, International Atomic Energy Agency (IAEA), Vienna, Austria, and the German Science Foundation research unit DASIM (Denitrification in Agricultural Soils: Integrated control and Modelling at various scales) and other institutes. It presents protocols, methodologies and standard operating procedures (SOPs) for measuring GHGs from different agroecosystems and animals using isotopic and related techniques that can also be used to validate climate-smart agricultural practices to mitigate GHGs. The material featured is useful for beginners in the field wanting an overview of the current methodologies, but also for experts who need hands-on descriptions of said methodologies. The book is written in form of a monograph and consists of eight chapters.

Book Description
Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.
