This is the first book in German on wastes from livestock and is the work of 11 authors, including the three editors. The first part deals with the composition, properties and behaviour of animal excreta. Of special importance is the account of pathogenic microorganisms (bacteria, viruses, protozoa, helminths, fungi), their occurrence in wastes, survival in the environment and epidemiological significance. Also discussed is air pollution through the formation of gases and through airborne microorganisms, and the breakdown of wastes in the soil. Part two covers collection, transport and storage of wastes, and part three the treatment of waste by biological and physical methods. After a description of methods of disposing of animal wastes on agricultural land an account is given of its utilization by plants and breakdown in the soil, with values for amounts which can be applied. An account is also given of water pollution through erosion and effluents. Part six gives a full account of disinfection of cattle, swine and poultry wastes during storage, by aeration and composting, and by physical and chemical methods, and part seven deals with the problems of smells. Part eight deals with silage effluents and the final parts with legislation for avoiding environmental pollution, and planning in the siting of livestock farms. The book has many clear tables, graphs and illustrations, literature references at the end of most chapters, and a subject index.
