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.…
Predicting Manure Nitrogen and Phosphorus Characteristics of Beef Open Lot Systems
This project involves the analysis of a new data set for manure characteristics from open lot beef systems demonstrating both average characteristics and factors contribution to variability in manure characteristics among these systems. Defining the characteristics and quantities of harvested manure and runoff from open earthen lot animal systems is critical to planning storage requirements, land requirements for nutrient utilization, land application rates, and logistical issues, such as equipment and labor requirements.…
Characterization of Nutrients and GHG Emissions from Separated Dairy Manure
This study has the objectives of characterizing dairy manure pre and post solid-liquid separation (SLS), estimating and comparing processing efficiencies between different technologies, and relating emissions to manure characteristics by using modeling tools.
What did we do?
Manure samples from nine dairy farms in southern and eastern Wisconsin were collected every two weeks.…
Adding Color to Your Program…People and Personalities
Asking a client to share their communication style and preference isn’t necessarily the first thing that’s done when contacted for help about manure management. However, it’s been shown time and again that communicating to a person in the way that matches the way they want to be communicated to, is the best way to ensure everyone is acknowledged and heard.…
The Use of USDA-NRCS Conservation Innovation Grants to Advance Air Quality Improvements
USDA-NRCS has nearly fifteen years of Conservation Innovation Grant project experience, and several of these projects have provided a means to learn more about various techniques for addressing air emissions from animal agriculture. The overall goal of the Conservation Innovation Grant program is to provide an avenue for the on-farm demonstration of tools and technologies that have shown promise in a research setting and to further determine the parameters that may enable these promising tools and technologies to be implemented on-farm through USDA-NRCS conservation programs.…
Soil Type and Short-Term Survival of Porcine Epidemic Diarrhea Virus
Manure management practices recycle nutrients in animal manures for crop production. Harmful microbes and viruses in the manure are generally reduced in the soil environment over time. The soil properties influencing how long animal virus persistence are poorly understood and may be specific even down to the type of microbe present. …
On-Farm Research and Student Engagement to Assess and Promote Manure and Mulch as Land Treatment Practices in Nebraska
In regions of intensive livestock production, like many areas in Nebraska, significant amounts of livestock manure are produced and, at times, underutilized. Manure positively impacts soil health, has been shown to reduce runoff and erosion, and is no more of a pollutant risk than commercial fertilizers when applied responsibly and at appropriate rates.…
Cataloging and Evaluating Dairy Manure Treatment Technologies
Proceedings Home | W2W Home 
Purpose
To provide a forum for the introduction and evaluation of technologies that can treat dairy manure to the dairy farming community and the vendors that provide these technologies.
What Did We Do?
Newtrient has developed an on-line catalog of technologies that includes information on over 150 technologies and the companies that produce them as well as the Newtrient 9-Point scoring system and specific comments on each technology by the Newtrient Technology Advancement Team.…
Microarthropods as Bioindicators of Soil Health Following Land Application of Swine Slurry
Proceedings Home | W2W Home 
*Purpose
As producers of livestock and agricultural crops continue to focus significant efforts on improving the environmental, economic, and social sustainability of their systems, increasing the utilization of livestock manure in cropping systems to offset inorganic fertilizer use benefits both sectors of agriculture.…
Spotlight on Manure Management in North Carolina and the Atlantic Coastal Plains
Proceedings Home | W2W Home
Purpose
To provide information about commonly-found manure management systems and approaches in North Carolina and the Coastal Plains, and discuss opportunities for technological innovation in the areas of manure management and nutrient recovery/utilization. Hear from a diverse panel of researchers, animal agriculture producers, and agency representatives who will provide background on the environmental conditions of the region and discuss specific technical considerations for innovative research and development.…
