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?”
