Looking Ahead to May: "Micro" Manure Management

composted dairy manureManure management often focuses on the "big" picture - tons applied, size of equipment or storage, etc. This webinar will take a look at the smallest manure managers (microbes & soil meso-fauna) and how their work can drive farming systems. We are featuring three Waste to Worth posters on soil arthropods, inoculated deep litter systems for pigs, and composting dairy manure with grapevine prunings. More...

What's Going On In the LPELC?

Waste to Worth: Spreading science and solutions logoWaste to Worth recordings.  The recordings from the Waste to Worth conference are being added to the proceedings papers as quickly as possible. Most of the Tuesday sessions have been completed.  A topic-by-topic and author search page are being created. | Add your photos to the slide show | Facebook page

Dairy Climate Conference.  The LPELC climate team (northeast region) is hosting a Dairy Environmental Systems and Climate Adaptation conference July 29-31 in Ithaca, NY. Registration is now open. More...

Neighbors.  Kevin Erb at the University of Wisconsin authored a new resource on neighbor relations. The article is based on information gathered from dairy farmers on ways they work with their neighbors. More...

Around the "Horns"

Manure Expo Slogans. The 2015 North American Manure Expo already has a slogan "Manure Than You Can Handle" but the organizers are looking for more! Visit the manure expo website to submit your "crappy" slogan for a chance to win a free T-shirt! (Entries due today - May 15!). Check out some of the entries already received....

Climate Change. The US Environmental Protection Agency (EPA) has released the annual greenhouse gas inventory. New this year is a data explorer that allows a user to look at individual sectors or gases and examine trends over time. More... Especially take a look at the enteric fermentation and manure management numbers to get a handle on the animal agriculture contributions to man-made emissions.

Regulations & Court Cases. The widely reported court ruling against a Washington dairy has resulted in settlements with the other dairies involved. The scheduled federal court hearing was cancelled as a result. The details of the settlement have not been released. This case has been watched closely as it was the first to apply the term "solid waste" to manure under the Resource Conservation and Recovery Act (RCRA). More.... | Related: The DAIReXNET team is planning a July webinar on this situation (the LPELC is a co-sponsor). Watch for announcements in future newsletters.

Nutrient Management

  • Four federal agencies have joined forces to create an early warning system for toxic algae blooms. More...
  • University of Illinois research shows that wetlands created 20 years ago continue to filter nitrates in runoff from tile-drained fields. Researchers also measured nitrous oxide emissions and found that the releases were minimal. More....Related: Recent LPELC webcast on Manure Management on Tile Drained Lands

Avian Influenzapoultry in building

  • The highly contagious bird flu that is spreading across the U.S. has already resulted in large numbers of euthanized birds and the estimates continue to climb. USDA APHIS has a good biosecurity site. Suggested resources for handling large-scale poultry mortalities:

Hormones. Trenbolone acetate (commonly implanted in beef cattle) is metabolized by the animal into 17-alpha-trenbolone which is excreted in manure. Once in the environment, the metabolites are quickly broken down in sunlight and that is the end of the story. Or is it? A recently published study modeled previous work that indicated that the reaction can reverse course in the absence of light - like those found in some aquatic environments. These models estimate that 17-alpha-trenbolone levels may be 35% higher than previously thought. More...  (includes a short video of one of the researchers talking about the work) | Abstract...

Communication. This Minnesota article shares advice for working with the local regulatory authorities, in this case the county feedlot officer. More...

Funding Opportunity. [Due May 22] The U.S. Environmental Protection Agency Chesapeake Bay Program (CBP) through its Expert Panel Management Cooperative Agreement with Virginia Tech is seeking proposals to assemble an Expert Panel to determine pollution control performance measure estimates for a suite of animal waste management system best management practices (BMPs). View the RFP for more details about the scope of work and evaluation process for proposals. The RFP is available online at 

Manure Composting. The Horse magazine published a "how to" article on building horse manure composting facilities. More... | Related: Managing Manure on Horse Farms
