Book Description
The majority of meat, milk, and eggs consumed in the United States are produced in concentrated animal feeding operations (CAFO). With concentrated animal operations, in turn comes concentrated manure accumulation, which can pose a threat of contamination of air, soil, and water if improperly managed. Animal Manure: Production, Characteristics, Environmental Concerns, and Management navigates these important environmental concerns while detailing opportunities for environmentally and economically beneficial utilization.

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
Dairy farming systems have been rapidly intensified over the past several decades in many world regions. One of the primary challenges in these intensive dairy farming systems is managing manure in a way that benefits agricultural production while minimizing environmental impacts. To increase the understanding of losses of manure constituents during manure management, we first zoomed in on gaseous emissions (mainly NH3, CH4 and N2O) from different manure management facilities. By conducting systematic literature reviews, we found large variation in reported nutrient losses across publications, especially for NH3 and CH4 emissions. Manure characteristics and temperature were identified as the main factors influencing these gaseous emissions. Based on the database compiled from systematic literature reviews, we proposed a modular approach and developed a flexible modular manure management (FarmM3) model. With contrasting manure management scenarios, the FarmM3 model allowed to quantify the degradation and losses of different manure constituents (e.g., OM, C, N, P and K) from manure management chains with different complexity, and to identify the most important parameters determining these losses. For highly intensive confinement dairy farms, improving manure management alone may not be enough to reduce nutrient losses due to high nutrient surpluses within farms. Thus, we zoomed out from nutrient losses from manure management chains and further investigated the impacts of various manure management chains and integration of crop and dairy production on nutrient use efficiency and circularity at whole farm level, including different farm components, such as dairy, manure, soil and crop. To simulate this, a whole farm model (FarmDESIGN) extended with a manure management module (FarmM3) was used to an intensive mixed crop-dairy farm in China. We found that manure management chains could be designed effectively to reduce nitrogen volatilization and soil N losses while improving soil OM balance. However, individual manure management technologies were insufficient to reduce N losses due to compensatory losses. Instead, combinations of slurry solid-liquid separation, covered storage of solid and liquid fractions during storage, and improved manure application could remarkably reduce N losses at manure management. Overall, we concluded that, to move towards sustainable intensification of dairy production, increasing nutrient circularity by improving manure management with multiple mitigation measures and integrating crop and dairy production within farm or between farms are essential. Policy support and improved communication of manure treatment technologies can facilitate adoption of improved manure management practices. Additionally, recoupling crop and dairy production beyond the farm scale is necessary for intensive dairy farms with limited land availability, and participatory approaches can help design effective scenarios for crop-livestock integration at the local or regional level.

Book Description
Focusing on the different types of grassland farming and their impact on the environment, this book addresses issues facing environmental quality, namely soil, water and air quality and socioeconomic impacts. It also offers a commentary on how the different pastoral sectors influence environmental issues.
