Manure Management Economics

Agriculture and Resource Economics have been investigating several issues related to animal waste. One is how regulation of animal waste is impacting the hog industry. Other research looks at some of economic implications of agricultural engineering solutions to manage animal waste. Several economists in the program have been researching the impact of hog farm locations on real estate property values.

Faculty members involved in these projects are Kelly Zering and Tom Vukina.

The Smithfield Agreement

An overview
Phase One Reports
Phase Two Reports
Phase Three Reports

An overview and links to major components (phases) of the research conducted.

In the summer and fall of 2000, the Attorney General of North Carolina entered into agreements first with Smithfield Foods and its subsidiaries and then with Premium Standard Farms under which the two companies consented to fund development of environmentally superior waste management technologies for use on North Carolina swine farms owned by the companies.

A Summary Report for Phase One

Phase One reports (dated July 26, 2004) generated under the Smithfield Agreement; includes overview and links to a summary report, and links to 5 appendices that include several reports related to each of 9 technologies evaluated in Phase One.

Summary Reports for Phase Two

Phase Two reports (dated July 25, 2005) generated under the Smithfield Agreement; includes overview and links to a summary report, and links to three appendices with numerous reports including 11 economic reports related to methodology and cost and returns of technologies evaluated in Phase 1 and in Phase Two.

Phase Three and Final reports

Phase Three and Final reports (dated March 8, 2006) generated under the Smithfield Agreement; includes overview and links to a summary report, and links to five appendices with numerous reports including 11 economic reports related to cost and returns of technologies evaluated in Phase One and in Phase Two.

Follow-up studies on Terra Blue technology

A follow-up study on 2nd generation Terra Blue Technology

A follow-up study on 2nd generation Terra Blue Technology (formerly called Super Soils USA) dated November 1, 2007: includes links to a summary report and two appendices including an economic report.
