Airborne bacteria and endotoxins (bioaerosols) have been detected fairly long distances downwind from livestock operations. Two research studies examining the formation of bioaerosols and their offsite transport will be presented. Assessing risks to downwind populations will be the primary focus of the webcast. More... .

Survey.What are the important issues in animal ag and environmental stewardship? What can the LPELC do better to help professionals making decisions that impact environmental management on farms? Tell us in a short (5 minutes, I promise) survey. If you take the survey and send the link to a few of your colleagues with encouragement to answer the questions, email me (jheemstra at unl.edu) and I'll enter your name in a drawing to win one of several cool prizes - like a portable hard drive, LPELC polo, or a "juice pack" (on-the-go charger for your mobile devices). Go to the survey...
Climate Course. Want to learn more about climate change and how it can impact animal agriculture? Do you want to be ready when an extreme event raises questions about climate among your clientele? Check out the comprehensive online course that includes topic like: 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.

Nutrient Software. The University of Missouri has released an online nutrient planning tool that allows users to map fields and identify vulnerable areas from which manure or fertilizer application should be set back. The software calculates field sizes and gathers soil data and allows for export to other programs. More... Related: Manure Nutrient Management
IPCC AR5. The second working group of the Intergovernmental Panel on Climate Change released its 5th Assessment Report (AR5) on "Impacts, Adaptation, and Vulnerability" which focuses heavily on impacts to human populations but does briefly discuss agriculture and water resources in that context. The final report in the cycle, the synthesis report, is expected toward the end of 2014. More...
Methane Reduction. The White House recently released the "Climate Change Action Plan - Strategy to Reduce Methane Emissions". The strategy looks at several sectors, including agriculture. The dairy industry is especially emphasized as a partner in the effort to reduce ag methane emissions. More... | Related: Sources of Greenhouse Gases | Greenhouse Gases and Agriculture (self study)
AgSTAR Website. The US Environmental Protection Agency (EPA) AgSTAR website has recently been "remodeled" and improved. If you are looking for information on anaerobic digestion, this should be among your first stops. More... One of my favorite sections if the profiles of farm projects which is searchable by state, digester type and animal species. | Related: Introduction to Biogas & Anaerobic Digestion

Manure Antibiotics. A European research project examined the impact of the presence of antibiotics, specifically sulfadiazine (SDZ), in animal manure had on soil microbes when that manure was applied to soil samples in laboratory settings. The study examined different levels of manure, different dosages of SDZ, and the effects of time. They concluded (not surprisingly) that the presence of SDZ significantly altered microbial populations in the soil samples.

PEDv. South Dakota State's Erin Cortus provides a nice overview on some of the research-based recommendations on disinfecting manure handling equipment to prevent spreading the PEDv virus between pig farms. More... | Related: Manure & Biosecurity
Livestock Methane. A National Academy of Science (NAS) study questioned the EPA estimates of agricultural and fossil fuel methane emissions, asserting the estimates were far too low. Pennsylvania State University took a closer look at the NAS methodology and used a different method to calculate livestock methane emissions. They concluded that the EPA estimates are accurate. More... | Related: LPELC Climate Change
Pig Probiotics. USDA Agricultural Research Service (ARS) research has found that pigs fed high-fiber diets are better able to digest that fiber (and reduce the amount of manure they produce in the process) when co-fed a specially-isolated bacterium. More...
