This Web site contains a June 2003 report from the Economic Research Service of U.S. Department of Agriculture. The report offers a detailed analysis of livestock and poultry manure management for water quality in the U.S. The studies included in the report occur on multiple scales: 1) a farm-level analysis of "on-farm technical choice and producer costs" across the U.S., 2) a regional analysis of off-farm competition for land for the purposes of spreading surplus manure, and 3) a look at "potential long-term structural adjustments at the national level," including costs to consumers and producers. Users may download the entire report (about 1.6 MB) or selected chapters. The report also includes a nicely-presented 2-page research brief.
