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.

Animal manure was a scarce and valuable resource in history. However, with the relatively cheap and easy handle synthetic fertilizers becoming easily available, livestock manure has turned from a resource into a waste or a pollutant to the environment, especially in industrial size farms or regions with high livestock density. Chinese livestock production has been developing quickly towards specialized intensive production in recent years. Most of the intensive farms has little or no cropland, which making manure management and utilization complex and difficult. The large amount of manure excreted and unproperly managed has cause a lot of social and environmental problems such as ammonia (NH3) emissions, greenhouse gas (GHG) emissions and water eutrophication. These increasing environmental problems have attracted attentions from scientists and governments. Many researches have been conducted and several regulations have been announced aiming at solving the problem. However, livestock farmers as one of the stakeholders in the management process are usually overlooked by the researches and regulations. Their adoption of techniques, and the drivers and barriers for them to use advanced techniques are unknown in China, which making the effectiveness of the regulations very limited. Therefore, the objectives of this PhD thesis include: i) to understand the adoption of manure management techniques and the drivers and barriers for those adoptions; ii) to estimate the impact of current management and explore options to mitigate the negative impacts. The work was mainly conducted with farm surveys and farmers’ interview on intensive dairy and poultry farms in Hebei and Shandong provinces, which were the major livestock production areas in China. With this survey data, in Chapter 2 the adoption rate of manure treatment techniques was analysed. Solid-liquid separation, anaerobic digestion, and composting were the only three techniques found in the survey. For dairy farms, 39% of the farms were equipped with solid-liquid separator, another 13% with anaerobic digestor and 6% with composting. However, most of the equipment were not used in practice and the actual operational rate was very low. For poultry farms there were almost no treatment at all. Interviews with farmers revealed that subjective norms from social referents, particularly from government agencies, were the main driver for the adoption of treatment techniques. However, the financial burden and technique failure hinder the adoption in practice. Even though Chinese government provided subsidies for the construction cost, the high operational cost and the bad manure market make the cost and the benefit unbalanced. Farmers therefore had low intentions to use these techniques. Chapter 3 focused on crude protein (CP) content in animals’ diet ration, because CP content determines nitrogen excretion in manure. When CP content exceed a certain level, animal productivity cannot increase further but N excretion in manure increases quickly. Therefore, low protein feeding is suggested by many researches as an effective method to reduce N excretion. Collected samples from mixed diet rations show that the mean CP content of animals’ diet ration was close to literature recommendations. However, there were large variations among farms, which indicates that there are still potentials to reduce CP content on some farms. Feeding companies actually defined the feed ingredients and nutritional values of animal diet rations. Farmers knew little about the importance of protein and the crude protein content of their animal rations. Speaking of low protein feeding, farmers were worried about the potential negative impacts on their production and financial risks. The results indicate that implementation of low protein feeding needs the active involvement of feeding companies, and more trainings are needed to help farmers understand feed protein better. In chapter 4 a model was developed to quantify the N and P flows based on mass balance approach. With the manure management information in each step collected from the farm survey, N and P flows in the management chain were quantified. On average 197 kg N and 30 kg P were excreted per cow per year (including young stock) and there was a substantial variation among the farms in NUE (53±20%) and PUE (84±22%) at farm level. Effects of management technologies varied greatly among farms; increases in farm-level NUE ranged from 0-53% and for PUE from 0-79%. Improving manure storage and treatment technologies and increasing manure export had relatively large effects on farm-level NUE and PUE and nutrient losses, while effects of low-protein feeding were limited. In chapter 5 the relationship between livestock density and soil P content was analysed at county and farm levels. Relationship between livestock density and soil P content was found to be insignificant at county level with the statistical data. However, at the farm level, livestock farms with cropland tended to have higher P content than crop farms without livestock in topsoil, mainly because that livestock farms with cropland tended to apply excessive amount of manure to cropland. The results indicate that manure was over applied from livestock farms but were not well utilized from crop farms. The results from this thesis point to the need for improved manure utilization in cropland, for developing a functioning ‘manure market’ with the involvement of middlemen, and for manure application limits for cropland on livestock farms. Hopefully, this thesis will contribute to improving manure management at farm level and to improving the sustainability of agriculture in practice.

This book highlights the underlying principles and outlines some of the key hi-tech practices and technology interventions required to achieve enhanced productivity. It discusses horticulture technology interventions like varietal improvement including genetically modified crops; good agricultural practices like optimum planting density, micro-irrigation, fertigation, integrated nutrient management, plant bioregulators, precision horticulture, protected cultivation, nanotechnology, and integrated farming systems; integrated management of insects, mites, disease pathogens, nematodes, and weeds; and post-harvest management practices like handling, storage and processing to reduce crop losses. The importance of attaining food and nutritional security through hi-tech horticulture and profitable marketing of horticultural produce is also discussed. This book will be of immense value to the scientific community involved in teaching, research and extension activities related to hi-tech horticulture strategies for enhancing productivity in enhancing farmers’ income, food, nutrition and livelihood security. The material can be used for teaching postgraduate courses. The book can also serve as a very useful reference to policymakers and practicing farmers.
