Proper Closure of Earthen Manure Storage Structures
When confined animal facilities cease operation, earthen manure storage and treatment structures must be closed properly to ensure that they pose little risk to the environment.

National Air Emissions Monitoring Study (NAEMS) Selected Results and Discussion of Their Significance
This webcast highlights the findings of the National Air Emissions Monitoring Study (NAEMS). The purpose of the NAEMS was to measure emissions of regulated gases from representative livestock and poultry facilities across the U.S. and improve the state of knowledge of agricultural air emissions, especially in the context of prospective regulation of those emissions. This webcast was originally broadcast on September 16, 2011. More… Continue reading “National Air Emissions Monitoring Study (NAEMS) Selected Results and Discussion of Their Significance”
Spreading Manure In Winter. What Are the Risks?
This archive was recorded from a live presentation at the 2011 North American Manure Expo. Kevan Klingberg, University of Wisconsin Discovery Farms discusses how application of manure nutrients on frozen and snow-covered soils became such a hot issue. He also explains their research program that monitors surface water quality on commercial farms. Lastly, he discusses the results of the research and how that information is being used to make management decisions on farms. Note: The recording volume was set high on these segments. Start with your speaker volume on low and move it louder if needed. Originally broadcast July 20, 2011. Continue reading “Spreading Manure In Winter. What Are the Risks?”
Improving Implementation of NMPs
This webcast covers three topics to help AFO operators understand how terms of CAFO discharge/operating permits relate back to the NMP, and how the NMP implementation can be improved and better documented: (1) U.S. EPA NMP permit terms, (2) perspectives on how better implement a NMP and (3) improved record keeping. This presentation was originally broadcast on June 24, 2011. More… Continue reading “Improving Implementation of NMPs”
Anaerobically Digested Manures
This webcast shares information on: monitoring protocols for anaerobic digesters, fate of nitrogen from manure after it has been anaerobically digested (AD), effect of AD manure on grass yield and nitrogen uptake, the fate of bacteria from manure after it has been AD, and the fate of bacteria after land application of AD manure. This presentation was originally broadcast on May 21, 2011. More… Continue reading “Anaerobically Digested Manures”
Planning Livestock & Poultry Facilities for Reduced Odor Risk
This webcast highlights two planning tools – OFFSET and NOFT – currently being used in western Cornbelt states to encourage well-planned siting of facilities and voluntary adoption of odor control technology. More… Continue reading “Planning Livestock & Poultry Facilities for Reduced Odor Risk”

Changing Management of Nutrients in the Chesapeake Bay Watershed
The objective of this webcast was to outline highlights of water quality data and political drivers that will shape the future of agricultural nutrient management in the Chesapeake Bay watershed. This presentation was originally broadcast on February 18, 2011. More… Continue reading “Changing Management of Nutrients in the Chesapeake Bay Watershed”
Utilizing Liquid Livestock Manure as a Top-dress to Wheat and Side-dress to Corn
This webcast discusses five years of on-farm research plots where liquid swine and dairy manure has been applied to soft red winter wheat fields and compared to urea as a spring top-dress nitrogen source. Research plots have utilized a Veenhuizen toolbar and a Peecon toolbar to incorporate liquid manure into standing wheat and more recently a dragline has been utilized to make manure application more efficient and reduce soil compaction. This presentation was originally broadcast on January 21, 2011. More… Continue reading “Utilizing Liquid Livestock Manure as a Top-dress to Wheat and Side-dress to Corn”
