Manure application in winter brings increased risk of runoff reaching surface or groundwater resources. Practical and science-based options exist for managing and reducing the risk for livestock producers who have little or no manure storage, or for situations where a late fall or early freeze limit manure application options. This presentation was originally broadcast on November 21, 2014. More… Continue reading “Winter Manure Application Options”
Linking Feed Management to Whole Farm Nutrient Management
Nutrients in feed is the primary source of Nitrogen, Phosphorus, and Potassium that is imported to livestock and poultry farms. This webcast highlights a decision aid tool that follows the nutrients in feed all the way to the land application of manure for crop production. This presentation was originally broadcast on October 17, 2014. More… Continue reading “Linking Feed Management to Whole Farm Nutrient Management”

Managing Biosecurity to Control Porcine Epidemic Diarrhea virus (PEDv)
The appearance of the Porcine Epidemic Diarrhea Virus (PED) in North America presents significant challenges for manure applicators. Since the virus is primarily spread by fecal-oral contact and can survive in manure for extended periods of time, it is possible for the disease to be spread by any object that becomes contaminated with infected pig manure. Biosecurity is an important part of preventing its spread. This presentation was originally broadcast on July 18, 2014.

EPA’s Proposed Waters of the U.S. Regulations
Update: March, 2017. The Trump administration has issued an executive order directing the EPA and Army Corps of Engineers to review the rule and revise or rescind the rule as appropriate. More…
Update: February, 2016. Multiple challenges to the rule in district courts were consolidated in the Sixth Circuit Court of Appeals. Full text of ruling….
Update: October, 2015. A ruling by a district court in North Dakota (August 27) blocked the implementation of the rule. EPA felt that the injunction only applied to the 13 states that were involved in bringing the lawsuit and announced it would apply the rule in the other 37 states as scheduled. On October 9, 2015 a federal appeals court ruled that the injunction applied to all states & territories and that EPA could not implement the rule as they planned.
Update: August, 2015. The finalized rule has been published
In this webcast, Rose Kwok of EPA’s Office of Water, and Ken Kopocis, senior advisor in the EPA’s Office of Water, will explain the proposed rule and discuss what the proposal would mean to the agriculture sector. This presentation was originally broadcast on June 20, 2014. More… Continue reading “EPA’s Proposed Waters of the U.S. Regulations”
