Webinar #2
Response to Questions and Comments about the Report, recorded Monday, May 16, 2016

The second webinar addressed questions and comments regarding the Manure Irrigation Workgroup report published April 14, 2016.


About the Workgroup
University of Wisconsin-Extension and UW-Madison convened a Manure Irrigation Workgroup at the request of the Department of Natural Resources and the Department of Agriculture, Trade and Consumer Protection to review issues and develop guidance on the practices of applying livestock manure or process wastewater through irrigation equipment – referred to as “manure irrigation.” 

The workgroup was composed of scientists, public health specialists, state agency experts, farmers, and others intended to bring a diverse set of perspectives to the issue. The workgroup met between July 2013 and September 2015 to explore benefits, concerns, and remaining questions associated with manure irrigation. The group had no formal authority, and its work does not establish policy on manure irrigation.

The navigation tabs at the top of the page provide more information about the workgroup activities, presentations from meetings in 2013, benefits and concerns associated with manure irrigation, additional resources, and information about how to share your comments.
