The study investigated the potential for nutrients in headland stacked poultry manure to impact surface or groundwater quality. Researchers found that the nutrient content of different types of poultry manure were generally consistent, allowing the use of average nutrient values. Poultry manure was also found to have excellent water holding capacity, absorbing about 37% of its weight in water. Infiltration tests found water moved through stacked poultry litter at a rate of 11.46 seconds per inch under extreme pressure conditions, though actual field conditions would result in a slower rate. Overall, the study concluded headland stacking of poultry manure has very limited potential to pollute surface or groundwater due to the material's ability
