What's Going On In the LPELC?

Nexus Conference. Texas Agrilife Extension (in partnership with the LPELC Animal Ag Climate Change team) will host a conference "Navigating Agriculture through the Water-Energy-Food Nexus" Symposium. This will be held in Austin, TX on November 19, 2015. Registration is limited to the first 200 people. More... | Flyer & Agenda...

Phosphorus CEUs. Certified Crop Advisors (CCA), Professional Soil Scientists (CPSS), or Professional Agronomists (CPAg) can receive three continuing education units (CEUs) in nutrient management by reviewing the phosphorus-related sessions from Waste to Worth 2015 and taking the quiz on the page. The presentations cover legacy phosphorus, phosphorus retention structures, and regional assessment of phosphorus risk tools. More...

Around the "Horns"

Dung Beetles 

  • European research found that a common parasite treatment/prevention, ivermectin, for livestock persists in the manure and soil after it is excreted by the animal. This drug had some negative effects on dung beetles and, in turn, negatively impacted dung decomposition in areas where treated animals defecated. More...
  • A nice primer from Beef Magazine on dung beetles, the benefits, and some basics about this beneficial insect. More...

Nutrient Management

  • A long-term US Geological survey monitoring effort was recently published. It showed nitrate levels in rivers in several highly agricultural areas with data showing a significant increase in nitrates from 1945 to 1980. The increases have not been as great since then, but have not declined as hoped. More... | Journal article...

Manure Videos. If you are looking for some manure-related video clips, check out the Iowa Manure Management Action Group video page. There are videos on water quality, manure value, PEDv, calibration and more... Some other manure-related video resources you may find interesting include: Cornell Waste Management Institute | Oklahoma State Waste Management YouTube channel | LPELC's YouTube channel. If you know of or maintain a resource that should be added, put it on the Animal Ag & Stewardship video resources spreadsheet. If we get some new additions, we will share this spreadsheet again.

  • Porcine Epidemic Diarrhea virus (PEDv) has moved to a back burner in the minds of many since the 2013 outbreak that killed millions of pigs. PEDv is still present and some worry that a drop in vigilance in biosecurity practices may allow a new outbreak to gain hold. Some places to watch for potential transmission of the virus are summarized in this story. More...
  • Oklahoma State University released the latest "Poultry Practices" newsletter. This issue focuses heavily on highly pathogenic avian influenza (HPAI), managing mortalities and biosecurity practices to prevent new outbreaks. More...
  • Kansas State University has been doing research on the transmission of PEDv through feed and found it takes very little contaminated manure to infect very large amounts of feed. More...

Not Enough Manure. A couple of different articles caught my eye this past month. Both discuss a study that says the planet does not have enough manure. This study is discussing wild animals and marine environments and looking at how reduced populations of large animals has caused less nutrient (in the form of manure) to be cycled and moved around the ecosystem. I guess manure management is an issue of distribution whether from domestic or wild animals. Journal article... | Articles from The Australian... | Live Science...

Big Data. Who owns the data gathered on farms about fertilizer rates, soil samples, or even nutrient management plans? The House Agricultural Committee recently held a hearing to examine the role of "big data" in agriculture. More... 

cow grazingGrazing Management

  • A study in Texas looked at the greenhouse gas (GHG) mitigation potential in Southern Plains cow-calf production (forage-based). Ruminants, especially those consuming forages, are considered a large source of GHG's. This research included field measurements of soil carbon data as part of the picture as they believed it is not currently adequately accounted for in most analyses of the carbon footprint of beef cattle. They found that converting to multi-paddock grazing systems resulted in sequestration of carbon, turning that phase of production into a net carbon sink. They also indicate that regional differences are important and individual farm or ranch differences can significantly change the picture. More...
  • Also from Texas is a newly updated guide on using guardian dogs to protect sheep or goat flocks on pasture or range. More...
  • A guide to producing outdoor pigs in California has been released by the Alameda County Resource Conservation District. The comprehensive guide includes chapters on site selection, pasture management, farrowing and weaning, and much more...

Antibiotic Resistance. A Canadian research study compared stockpiling and composting manure in terms of antimicrobial resistance, the presence and dissipation of those microbes. Not surprisingly, the more active process of composting was more effective in reducing numbers of resistant bacteria. Abstract... | More...
