Webcast Series

Looking Ahead to May: Increasing the Manure Application Window - Sidedressing Liquid Manure on Emerged Corn

After a two-month break for Waste to Worth, the webcast series resumes with Glen Arnold, Ohio State University discussing his on-farm research on applying manure to standing crops. He will discuss results to date as well as what is being planned in the state of Ohio to capitalize on the opportunity to apply in-season nutrients with manure application.

What's Going On In the LPELC?

Waste to Worth.  The 2017 Waste to Worth conference was a huge success. Approximately 200 people from all over the country (and world) came together to create a conference that not only focuses on the science of animal ag and stewardship but also the application of that science. The information as well as opportunities for connecting were truly top notch.

  • Recordings - The recordings are being uploaded now. Almost all of the proceedings papers will have one added in the next two weeks. (see links below to access the proceedings)
  • Proceedings - Browse the proceedings by conference agenda or by topic (in progress - keep checking back throughout May). Those interested can download a printer-friendly version of the agenda.
  • Student poster winners - Congratulations to the winners (see photo right) and thanks to our judging committee. The future is bright in the world of manure management.
  • Slideshow - check out the photos submitted by participants for the conference photo slideshow

Around the Horns

Climate Change. Walmart recently announced an initiative to reduce carbon emissions from its supply chain by a gigaton. This includes an intent to reduce emissions from animal agriculture, especially beef and dairy production. News release... | Initiative website... Related: Animal Agriculture and Climate Change

Manure Expo. It is time to dust off your crappy puns and submit them to the "top 10 rejected Manure Expo slogans" Tshirt contest. Past entries have included gems such as "the future of what's left behind" and "nobody sticks their nose in our business". Join "the movement" and submit yours today! Read more...

Policy and Regulation. The DC Circuit Court has ruled that the rule under which farms are exempted from reporting under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and under which most farms were exempted from reporting under the Emergency Planning and Community Right to Know Act (EPCRA) is not valid. This change means that any farm that emits hazardous substances above the threshhold amount (for most farms this will be ammonia and/or hydrogen sulfide) will be required to report. Guidance on doing this is not yet available. Texas A&M Ag Law blog... | Related: LPELC Fact Sheet on the exemptions and resources for estimating emissions

Grazing Management.

  • USDA NRCS is hosting a webinar on "Using fire and grazing to maintain productive and ecologically resilient grasslands" on June 1, 2017 at 2 p.m. EDT. Read more or register...
  • Biodiversity is often not the primary goal of grazing management, but is the result of good grazing practices. Diverse grazing lands are more resilient and play a role in nutrient cycling and carbon sequestration. Researchers at Northern Arizona University have developed a model to assign a $ value to biodiversity (largely based on the increased carbon storage capacity of land with multiple plant species as compared to monocultures).

Anaerobic Digestion

  • Department of Energy researchers have developed a system to convert methane into a gel that has potential for use as a biofuel, among other uses. The process uses two different types of microbes, ones that produce the methane and others that capture the methane. Read more...
  • The EPA AgSTAR program is hosting a webinar on "Innovative Business Models for AD Projects Part 2" on May 24, 2017 at 2 pm EDT. Learn more or register...

Manure Value. The Manure Scoop blog from Iowa State University takes a look at how the nutrient content of swine manure changed over 15 years and compared those nutrient values with fertilizer prices. Bottom line: manure is valuable. Read more...

Nutrient Management

  • The Chesapeake Bay program has released a report on "Manure Treatment Technologies" in which an expert panel looked at different technologies through the lens of water quality goals for the Bay. Read the report...
  • Michigan State University has released a tool to advise farmers on the best times to spread (and not spread) manure. The online tool includes features such as the ability to sign up to receive text or email messages at times when nutrient application is at high risk for runoff in your location. Read more...
  • The April, 2017 issue of the Penn State Dairy Feed Management Newsletter includes articles on precision feeding, what makes farmers try new practices, and soluble phosphorus in soil. Find out how to get a copy or subscribe...
  • Iowa State University has released three new publications on calibrating liquid manure tank applicators and verifying distribution after calibration. Calibrating Liquid Tank Manure Applicators | Calibration Worksheet | Distribution of Liquid Manure Application

Organic Production. USDA has released a second proposed rule on organic livestock and poultry production. The Final Rule amends the organic livestock and poultry production requirements in the USDA organic regulations. This Final Rule was originally set to take effect on March 20, 2017, and is now being extended to November 14, 2017. Comments will be accepted until June 9, 2017. Read more...

Farm Demonstration Network. The University of California Davis has announced the formation of a Farm Demonstration Network to foster farmers' innovations. Producing more food with less resources while protecting the environment is a challenge that will require both the scientific expertise of Universities as well as the experiential knowledge of farmers and field staff. This follows a growing trend of state Extension programs developing on-farm research, learning farms, discovery farms (or similarly named programs). Read more...

Disaster Recovery. Kansas State University has updated a publication on "Management Following Wildfire". It provides guidance on when and how much to graze pasture and range while it is recovering from an unplanned fire. Read more... | Download the publication
