Webcast Series

Looking Ahead to January

The third in a three-part series of webcasts on nutrient recovery from manure treatment systems will examine topics related to swine systems, co-digestion, scale and efficiency. It will feature Curt Gooch, Cornell University; Brian Paulsen, Murphy Brown; Dana Kirk, Michigan State University, and Sasha Rollings-Scattergood; Anaergia, Inc. The webcast is January 17, 2014 starting at 2:30 (eastern). More...

Future Topics

February - Gasification technology for manure and algae biomass
March 7 - Water Quality Index for Agricultural Runoff (rescheduled due to government shutdown)
March 21 - On-Farm Manure Research Results (applying manure to standing crops)
April - climate change topic TBA
As always, you can check out the recordings of past webcast at our webcast archive and view the schedule at upcoming webcasts.

Can you compost mortalities in winter?

What's Going On In the LPELC?

Winter Spreading. With many winter manure spreading bans going into effect, it seems appropriate to review some of the research that has looked at risks of spreading manure on frozen and snow-covered ground. Check out these resources to learn more: Archived webcasts: Winter Spreading, What Are the Risks? and "Risk Assessment Tools & Advisories" | W2W proceedings: Will Bans Reduce Runoff Events?

Curriculum Materials. If you teach high school, college, jr. college, or continuing education programs, the LPELC has a large collection of curriculum materials ready for you to use. Air Quality | Climate Change | High school/cross referenced with national AFNR standards (includes: greenhouse gases, manure 101, nutrients, water, sheep & goats, poultry, and mortalities)

Climate Course. This self-paced course is specifically designed for Extension educators and technical service providers across the nation who serve livestock and poultry producers. Topics include recent weather trends, climate impacts, adaptation and risk management, basic climate science, greenhouse gas emissions and mitigation practices, the basics of carbon markets, and communication strategies for dealing with this contentious issue. Signups are available at the start of each month for this comprehensive course. More... | Brochure

FDA Revisions, Manure Apps, Energy Efficiency, SARE Index

FDA Revisions. The US Food and Drug Administration (FDA) released a statement indicating significant revisions will be made to the proposed rule known as the Food Safety Modernization Act. Due to extensive public comment, several areas, including the section requiring lengthy prohibitions of some crops after raw manure application, are going to be revised and subjected to additional public comment before the final rule is released.  More...

Manure Apps. The University of Arkansas recently released a free app "Manure Valuator" that helps estimate the dollar and nutrient value of manure as a crop input. More... | Related: Smartphone Apps for Manure Management

Hot Topics

Antibiotics, Pit Foaming, Plastic, Bioaerosol Risk

Antibiotics. The US Food and Drug Administration has issued guidance on the voluntary program to phase out some antibiotics in animal production. The program targets uses that improve feed efficiency or increase growth rate. More... On a related note, a new article in the New England Journal of Medicine points a finger directly at the use of antibiotics in food production as a "low-value" use that should be ended. More...

Pit Foaming. A multi-state research group is seeing signs of hope in their quest to identify the causes of manure pit foaming and find a solution. The problem has been on the rise in deep-pit hog buildings in the upper-Midwest for several years and has even led to explosions and flash fires when the methane-laden foam is ignited. The current breakthrough is in regards to a test that can be done on a sample of manure and provide an assessment of the risk of that manure pit developing a foaming problem. More...

Plastic. We have reported on this before, but it is so awesome it bears another mention. Manure transformed into biodegradable plastic. More...

Bioaerosol Risk. A USDA Ag Research Service study looked at the movement of bioaerosols (bacteria, fungi, and remnants--often carried with dust) from dairies. They reported that concentrations of these contaminants dropped off drastically as sampling was conducted further downwind of the facility, dropping from 426 to 56 endotoxin units (EU) at 165 and 655 feet from the barn.

Manure In the News

A look at animal agriculture and manure in the news, serious, funny or controversial. Inclusion here does not constitute LPELC endorsement. In other words, we don't create this stuff, we just link to it.

Most of us are well aware of the rise in the use of digesters for treating animal manure. We also know that digesters, by themselves, do not reduce the amount of nutrients in the manure, but can lend themselves to nutrient capture with add-on technologies for the system. In our work with farmers, the public, and ag professionals it is important to remember that not everyone understands the limitations or the benefits of these technologies. The following back-and-forth opinion articles reminded me of that...
