Research Project:
Trace-Gas Emissions from Dairy Production Systems
Project Number: 3655-12630-002-03
Project Type:
Specific Cooperative Agreement
Start Date: Sep 28, 2006
End Date: Sep 29, 2009
Objective:
The objectives of the time frame of 03/29/2007 through 06/28/2007 are: 1) Continue processing, analyzing, and summarizing data from measurement of ammonia emissions from three Wisconsin dairy farms that were completed during winter of 2006-2007; and 2) Plan, prepare, and then begin to implement the repeat measurement of ammonia emissions to be done on these same farms during the summer of 2007.
Approach:
Air emission measurements will be made periodically over one year from three prominent dairy farm types. Representative dairy operations will be selected from: 1) a pool of dairy farms participating in the National Dairy Emissions Project funded by the National Milk Producers Federation/EPA Consent Agreement (implemented by Purdue University); 2) a pool of dairy farm collaborators in the Air Quality/Odor Emissions Project of Wisconsin's Dept. of Agriculture, Trade & Consumer Protection; & 3) other dairy farms that might bolster ongoing research at DFRC & other dairy research collaborators. Whole-farm emissions may include measurements of ammonia & methane. Emission detectors & other equipment will be purchased & installed to evaluate emissions from each farm operation (whole-farm emissions) three times per year. Specific farm components (housing, manure storage, manure land-spreading) may be evaluated as time, resources, & interests become available. Gas concentration detectors & other equipment with atmospheric physics technology will be used to determine emissions remotely from farm production sites. Multiple detectors as available may be used to compare emission measurements.
