Adaptive Nutrient Management

The foundation of adaptive management is a rigorous and objective evaluation of management practices at the field level combined with a deliberate process to learn from the evaluations to make better decisions in the next season. The objective of this webcast is to teach participants about the concepts and practice of adaptive management in agricultural production. This presentation was originally broadcast on April 20, 2012.

Chesapeake Bay 2012 – Implications of the TMDL

This is a follow-up webcast to Changing Management of Nutrients in the Chesapeake Bay Watershed. That initial webcast told the story of why the TMDL was developed and the nuts and bolts of the TMDL as well as the next steps from 2010 to 2025. This webcasts shows the state response to the TMDL, the legal considerations of the TMDL and the effectiveness of policy interface between agriculture and the environment. This presentation was originally broadcast on February 17, 2012. More… Continue reading “Chesapeake Bay 2012 – Implications of the TMDL”

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”
