Reduction and fate of manure pathogens and antimicrobial resistance

Antimicrobial resistance is a complex issue as it is comprised of not only pathogenic bacteria, but also non-pathogens which share genes within complex environmental systems, such as agricultural fields. This webinar describes potential measures to reduce pathogen and antimicrobial resistance in manure as well as potential fate and transport of manure pathogens and antimicrobial resistance following land application of manure.…

New Technologies to Help Us Share Stories and Ideas

This two-part workshop exposes participants to a wide variety of existing and new technology, and how these applications can enhance learning and programming.

During each part of the session, there will be a series of short presentations, opportunity for sharing of ideas, followed by time to ask questions and try the tech at tables around the room.

Treatment Needs for Water and Nutrient Recycling

This livestock industry panel will present perspectives on livestock producer needs for liquid manure treatment technologies for on-farm sustainability, with emphasis on managing water and nutrients for reuse. Intended outcomes are to engage stakeholders in assessing farm needs and to foster improved connections between livestock producers and technology providers.…

Three Options for Cleaning Barn Exhaust Air

Reducing aerial emissions and improving air quality is a common goal in the livestock and poultry industries. This webinar presents three approaches to reducing aerial emissions from barn exhaust air, using combinations of wet scrubbing, electrostatic precipitation, filtration and enhanced dispersion.…

Winter Manure Application: Research Needs and Future Direction

To better understand the state of the science and to lessen the present risk of winter manure application, a literature review was conducted that examined a wealth of studies dating back to 1945. Interest in winter manure application has increased, in part, due to the high-profile nutrient impacts to the Great Lakes and the several resulting new policies that have been implemented within the surrounding states.

Minnesota’s Runoff Risk Advisory Forecast: Forecasting the optimal time for manure application

The Runoff Risk project was started in Wisconsin in 2011, with the realization at that time, there was no real-time runoff risk guidance available for manure applicators. The project has grown, with four states (Michigan, Minnesota, Ohio and Wisconsin) now operating real-time runoff risk forecast websites.

Sources of Agricultural Greenhouse Gases

The conversation about climate change largely revolves around greenhouse gases. Agriculture is both a source and sink for greenhouse gases (GHG). A source is a net contribution to the atmosphere, while a sink is a net withdrawal of greenhouse gases.  In the United States, agriculture is a relatively small contributor, with approximately 8% of the total greenhouse gas emissions, as seen in Figure 1.…
