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.…
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.…
Reducing or Mitigating Greenhouse Gas Emissions In Animal Agriculture
Animal agriculture has dramatically increased its production efficiency over time, as it continues to produce more products with fewer resources. Although its overall carbon footprint is relatively small compared to other sectors of the economy such as energy and transportation, it is often called upon to defend its impact on the environment.…
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.…
Greenhouse Gas Emissions from Livestock & Poultry
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 below. …
Using Manure to Improve Soil Health
This webinar looks at current practical research in South Dakota and Michigan related to manure use as it relates to soil health. This presentation was originally broadcast on March 1, 2019. More……
Separation Technologies for Capturing Nutrients from Manure
Exporting phosphorus and possibly nitrogen from larger livestock operations as well as regions of large livestock populations is often essential for protecting water quality. Solids (and nutrient) separation technologies are an option for concentrating nutrients for export. This webinar introduces three approaches to solids separation that are being applied in commercial settings.…
