Speakers at the Nebraska Manure Demonstration Day
Speakers at the Nebraska Manure Demonstration Day
About the speaker: Trent is a sixth generation United States farmer with a passion for agriculture that started years ago – he had his first pig when he was just 5 years old on the family farm near Quincy, IL. When anti-agricultural activists threatened the way of life he cherished, it was time to take a stand, so Trent began speaking out for agriculture. Loos Tales, Trent's radio show, launched in January of 2001. In 2008, Trent was recognized as the "Voice of Rural America" by the West Quest organization for his ground-breaking work in advocating for agriculture and speaking on behalf of the folks who would rather stay home and tend to their crops and livestock than take on those attacking their life-sustaining industry. Trent and his wife Kelli enjoy life in central Nebraska with their three daughters.
About the speaker: Greg began his service as Director of the Nebraska Department of Agriculture in June 2005, receiving the appointment from Governor Dave Heineman after spending six and half years in the Assistant Director role. In addition to his director duties, with the help of his family he continues to maintain a cow/calf and grain operation near Sumner in central Nebraska. He shuttles between Sumner and Lincoln regularly and oversees all programs of the Agriculture Department.
Track 1 - Managing What We Can't See in Manure
Dan Miller - Intro to Manure Microbiology
About the presentation: Microorganisms play a central role controlling nutrient content and odor production during manure accumulation and storage. Their activities after application can also impact the gas emissions and fertilizer value. This presentation will focus on the basic microbiology of manure and how microbes can be managed to minimize potential environmental issues when manure resources are utilized during crop production.

About the speaker: Dan Miller is a microbiologist with the Agricultural Research Service in Lincoln, NE where he works as a team member investigating effective management solutions for a variety of manure management issues. In the past he has researched odor compound formation in feedlot and swine production systems and examined nutrient transformation and losses from manure-impacted environments.
Lisa Durso - Antimicrobial Resistant Bacteria and the Environment
About the presentation: The use of antibiotics in food animals is an issue that has captured national attention. But there is still a lot that we don't know about antibiotic resistance on the farm, or in manure-impacted soil and water. The public perception is that it is the agricultural use of antibiotics that creates resistance. Soil scientists know that antibiotics come from soil bacteria, and can occur naturally. This presentation will look at the idea of measuring naturally occurring and baseline levels of resistance as a prerequisite to identifying agBMPs that can have a real impact on human health.

About the speaker: Lisa Durso is a microbiologist working with the Agricultural Research Service. She works with a team finding ways to use manure as a resource, while minimizing adverse environmental impacts. Her current projects focus on determining the fate and transport of pathogens and antibiotic resistance in manure-impacted environments, measuring them in agricultural and natural settings, and evaluating new technologies for remediation of runoff from beef cattle feedlots. She is very interested in all aspects of "microbes in manure".

John Schmidt - Antimicrobial Resistant Bacteria and Food Safety
About the presentation: Bacterial antimicrobial resistance is an ancient, natural, and dynamic process. As such, the contributions of various human activities, including animal agriculture, on the occurrence and spread of antimicrobial resistant bacteria are complex and multifaceted. It is increasingly apparent that the complex issue of antimicrobial resistance will not be solved by simplistic actions such as the imposition of severe restrictions on the agricultural use of antimicrobials. Due to a lack of sustained inquiry, the scientific understanding of the ecology of antimicrobial resistance is very poor. Thus, the study of antimicrobial resistance in agriculture has great potential to increase scientific knowledge and may impact food safety, animal health, and human health.

About the speaker: John Schmidt is a microbiologist with the Agricultural Research Service at the United States Meat Animal Research Center located in Clay Center, Nebraska. He received a B.S. in Biotechnology from Rutgers University and a Ph.D. in Microbiology from the University of Illinois. Prior research has included genetics and biochemistry of bacterial mobile genetic elements, tumor virology, and the biochemistry of bacterial antimicrobial resistance. His current research is focused on improving the microbiological safety of beef and pork, and determining the impact of agricultural antibiotic use on the prevalence of antibiotic-resistant bacteria throughout the beef and pork production and processing continuums.

Shawn Shouse - Manure Runoff Management for Small Open Lots
About the presentation: While not subject to NPDES permit requirements, small open lot operations still need to prevent nutrient and pollutant losses to lakes and streams. This featured on-farm demonstration showed how open lot runoff can be inexpensively captured and utilized with and without pumping. Click here to download a PDF version of this presentation.
About the speaker: Shawn Shouse is an Agricultural Engineering Field Specialist for Iowa State University Extension and Outreach, stationed in the southwest corner of Iowa. With BS and MS degrees in Agricultural Engineering, he worked in the grain storage and farm building industries prior to joining ISU.

Andy Scholting - The Multiple Values of Manure
About the presentation: It is relatively easy to put a monetary value on the nutrients in manure. It is not as simple to determine how much of that value is real to each individual farm. This session will show how to value manure and touch on how to maximize the returns from that value. Click here to download a PDF version of this presentation.

Renee Hancock - Strategies for Phosphorus Management on Cropland
About the presentation: Nutrient management continues to be at the forefront of Environmental Issues facing livestock and crop producers. Phosphorus is one of the nutrients that plants need to grow, and for most of human history, farmers always needed more of it. But excess soil phosphorus levels leads to runoff and surface water pollution. My presentation considers ways to minimize phosphorus losses to surface water.

Prior to NRCS, she worked at NDEQ for 13 years. Renee graduated from UNL with a bachelors and masters in animal science, minor in science.
Afternoon Panel Discussion
About the panel: Livestock producers have manure. Crop producers need manure. What is the best way to connect the two so that both benefit from the use of animal manure as a crop fertilizer? This panel will feature a livestock producer, a crop producer, a custom manure hauler, and a nutrient management specialist presenting their thoughts on connecting animal and cropping systems to promote successful exchanges of manure.
Livestock Producer - Dan Roberts
About the panelist: Dan Roberts brings a unique perspective on manure management. After graduating from UNL with a degree in Animal Science he came back to the family feedlot and farming operation and has been invloved with that for the last 38 years. They have grown their farming to handle almost all of their feedlot nutrients. A few years ago he became a part owner of MMI international which manufactures mixer feeders and manure spreaders. His hope is that by being involved in all aspects of manure management it lends him to have a clear perspective of its management.
