Abstract

The problem of disposal of animal wastes has increased with modern methods of mass producing hogs, poultry, and other livestock and livestock products. With the increase popularity of confinement housing and the purchase of feed, less land is needed to raise more livestock and less land is available for disposal of the manure produced. Several methods for the disposal of hog manure have been suggested by various authors I the fields of agriculture and engineering. These proposed solutions include: field spreading, drying, composting, and lagooning. The purpose of this research was: to determine the extent to which lagoons were being used in South Dakota for the stabilization of farm manures particularly from hog operations, to determine if chemical analyses of lagoon liquid samples could be of assistance in evaluating the conditions responsible for objectionable odors from lagoon installation, to develop tentative design criteria for future lagooning installations serving hog operations applicable to South Dakota climatic conditions. Operating lagoons in South Dakota were located by using letters and questionnaires sent to county agricultural agents and farmers throughout the state. On site investigations were conducted at approximately ten selected lagoons so that the questionnaire information could be confirmed and further data collected. Physical observations included temperature, prevalence of odor, flies, mosquitoes, rodents, and over-all physical appearance. From this information, recommendations for future design and operational procedures for log waste lagoons in South Dakota were made.
