Around the Horns

PEDv. A recent University of Nebraska study examined the survivability of Porcine Epidemic Diarrhea Virus (PEDv) in different soil types and the effect of lime (increased pH) on the virus in manure. Lime was effective as PEDv was not detectable in the manure at either pH10 or pH12. The application should be done at recommended points in manure handling to avoid problems with the development of sludge or the release of high levels of ammonia. News release... | Study summary...

  • The US Geological Survey has a data visualization tool that shows the trends in water quality, including nutrients such as ammonia, nitrate, and phosphorus over time. Start using the tool...

Nutrient Management.

  • The Illinois Pork Producers Association and the Soybean Checkoff have funded a new "Illinois Manure Calculator" smartphone app. The free app calculates a manure application rate based on either nitrogen or phosphorus limits and commercial fertilizer that will be applied to the field. Read more...
  • Spring manure application shows benefits over fall application for crops and pastures according to an Iowa State University study. Read more...
  • The North Central Region Water Network is sponsoring a webinar on "Nitrogen Management in Tile Drained Landscapes" on April 19, 2017 at 2 p.m. CDT. Learn more or register...
