Looking Ahead to August & September: Mortality Composting-Beyond the Basics

a dead calf ready to add to mortality compost pileMortality composting is a practice that is gaining greater acceptance and use throughout the U.S. The advanced topics include: pile characteristics for effective composting, management and environmental considerations when siting and managing composting facilities, and mortality compost nutrients for on-farm use.  August 15, 2014 at 2:30 p.m. (eastern) More on Part 1 (August)... |  Part 2 will cover drug and prion persistence in piles, worker safety, and mortality composting resources. September 19, 2014 More on Part 2 (September)....

What's Going On In the LPELC?

Waste to Worth: Spreading science and solutions logoWaste to Worth. The abstract submission process is live. Start preparing your descriptions of research of your extension/education projects that should be showcased at this conference! Abstract submission closes on September 15. The conference is also looking for vendors and sponsors. Waste to Worth will be held in beautiful downtown Seattle within walking distance of the Space Needle, Waterfront, and public transit. The agenda and other information is available at  http://wastetoworth.org.

Climate Blog. The climate team has added a short weekly blog post to the great information they have already developed. Visit the blog to subscribe and check out the other resources.

Greenhouse Gases, Estuary Nutrients

Greenhouse Gases. The USDA Office of the Chief Economist has released a report on "Quantifying Greenhouse Gas Fluxes in Agriculture and Forestry". It lays out the methods for estimating changes in greenhouse gas emissions or storage at the local level. More... Also of note is the "State of the Climate" report released by the National Oceanic and Atmospheric Administration. | Related: LPELC climate team content on "Sources of Greenhouse Gases"

Gulf Hypoxia. The hypoxic zone (dead zone) in the Gulf of Mexico was mapped for 2014. It shows that the zone is still large (5,052 square miles) but smaller than 2013. More...

Estuary Nutrients. The US Geological Survey has updated its "Tracking the Source and Quantity of Nutrients to Our Nation's Estuaries" page. This resource also includes a decision support tool to estimate changes in nutrient transport based on differences in nutrient sources. More... | Related: LPELC manure nutrient management resources

State Program Highlights

  • Nebraska. The UNL manure management team hosted a Manure Demonstration Day on July 29 which included equipment demonstrations, educational sessions, and opportunities for participants to talk with vendors and other farms. More... Guest speaker, Trent Loos shared his observations on the field day.
  • Idaho. A field day showed the progress of a long-term trial examining the impacts of heavy manure applications, crop rotation, and alternated with inorganic fertilizer. More...
  • Ohio. Side-dress manure? Yes, this practice can make sense in more ways than one. Ohio State University recently held a field day about research into side-dressing manure on standing crops. More... | Related: Archived webcast Utilizing Liquid Manure As a Top-dress to Wheat and a Side-dress to Corn
  • Minnesota. A field day on the utilization of manure nutrients was well attended. The day also included a demonstration of a manure spill, using dyed water. More...
  • Michigan. A primer from MSU extension on keeping nutrients in the field and out of tile lines. The article also includes in formation on an August 28 field day. More...
  • Vermont. The University of Vermont has developed and released "GoCrop" a software program for efficiently tracking nutrient management practices. More...
  • Minnesota. UM extension engineers offer advice for managing manure storage in light of historic rains in the area. More...

Composting Solids, Digester Analysis, Manure & Rice, Beef & Environment, Comments Extended, PEDv Biosecurity

Composting Solids. A Danish research study looked at composting digested manure solids and how different bulking agents and mixing ratios affected greenhouse gas and ammonia emissions. Overall, it appeared that the addition of a carbon-rich bulking agent can retain nitrogen and reduce greenhouse gas emissions.  Abstract...

Digester Analysis. An article published in Global Change Biology Bioenergy modeled the life cycle of anaerobic digestion and examined the impacts that changes in feedstocks and post-digestate management can have on the overall greenhouse gas (GHG) footprint. They found that co-digested food wastes were an effective at reducing GHG's but that co-digested crops resulted in increases elsewhere in the system that tended to negate the benefits.  Abstract... The same research team has developed an LCA tool based on their work. More...

Manure & Rice. Does it make a difference if manure is composted or air dried when it comes to methane emissions from rice paddy soils amended with each? Yes, it does. A Korean study found that composted manure mitigated methane emissions as much as 50%. More...

Beef & Environment. The Proceedings of the National Academy of Sciences (PNAS) recently published an analysis from Weizmann Institute (Israel) in which they calculated the environmental costs of five sources of animal protein. They concluded that beef was over 10 times more costly [environmentally speaking] than any other protein source. News release.... | PNAS abstract... The Carnegie Institute for Science came to a similar conclusion. More...

Comments Extended. The US Environmental Protection Agency has extended the public comment period on the "Waters of the U.S." proposed rule until October 20, 2014. The comment period on agricultural exemptions was extended until July 7. More... | Related: LPELC archived webcast on the rule

PEDv Biosecurity. A recent survey from the Manitoba Livestock Manure Management Initiative shows that custom manure applicators are serious about refining (already stringent) protocols to prevent the spread of PEDv. More... | Archived webcast: Managing Biosecurity to Control PEDv Spread
