摘要

Management of the land disposal of fecal wastes from commercial poultry production operations requires managers to have specific knowledge of how much waste is generated, where it is generated and when and where it is disposed. Here we present a methodology developed to (1) identify poultry production locations, (2) estimate the amount of waste generated at each location, (3) identify the timing of poultry waste disposal and (4) identify locations at which waste from poultry production operations was disposed. The work done included: (1) air photo interpretation, (2) on-ground verification of the air photo interpretation, (3) review of animal waste management plans, (4) review of land disposal records and (5) direct observation of the land disposal of poultry waste. A total of 3,226 structures with a possible relationship to poultry production were identified by the initial air photo interpretation. On-ground investigation confirmed 1,917 of these to be active structures. The poultry waste produced was calculated based on a consideration of the amount of waste produced per unit area of poultry structure as a function of bird type. The data used to arrive at these values was obtained from animal waste management plans prepared under the supervision of the U. S. District Court for the Northern District of Oklahoma. This approach produced an estimate of annual poultry waste production in the Illinois River Watershed of 354,000 tons. The proximity of waste disposal locations to waste generation locations was determined from review of records maintained by the Oklahoma Department of Agriculture Food and Forestry. Review of these records showed that poultry waste was typically land disposed near its place of generation; 80% of poultry waste was disposed within 8 km of where it was generated. In addition, although poultry waste is disposed year round within the Illinois River Watershed, approximately 63.4% of poultry waste was disposed between February and June. Although poultry production companies have recently made an effort to export poultry waste form the Illinois River Watershed, review of poultry waste transportation records indicates that at most 19.5% of the poultry waste generated within the Illinois River Watershed in 2006 was disposed outside the Illinois River Watershed.
