The study consisted of 4 years of research conducted to determine the feasibility of the Plow-Furrow-Cover (PFC) method of manure disposal. The purpose of the research included the development of equipment and techniques for the disposal of poultry manure in soil, and measurement of the consequent chemical, physical, and biological changes. Various sections of the report describe the development of equipment; effect upon groundwater; laboratory decomposition studies and salmonella; and effect on soil water and the soil. Poultry manure was used as the organic waste, and there was no indication of groundwater pollution by fecal coliform. The upper limit of poultry manure disposal appeared to be less than 15 tons per acre of dry material because of nutrient contamination in the soil water. The PFC technique utilized the soil media for degradation and the eventual utilization and recycling of organic wastes by plants.
