Research Project: Effect of Manure Application Rate and Timing on the Leaching and Runoff Potential of Antibiotic Resistant Bacteria and Their Associated Gene

Location: Food Animal Environmental Systems Research Unit

Project Number: 6445-12630-004-15
Project Type: Trust

Start Date: May 01, 2013
End Date: Sep 01, 2014

Objective:
1) To determine if swine manure application rate to soil affects the leaching and runoff potential of antibiotic resistant bacteria and genes found in swine lagoon effluent. 2)To determine if manure application timing affects the leaching and runoff potential of antibiotic resistant bacteria and genes found in swine lagoon effluent.

Approach:
The fate and transport of antibiotic resistant bacteria and genes from land-applied swine manures will be evaluated using laboratory columns to determine leaching potential and runoff boxes to determine runoff potential. Different manure application rates and timing of manure application prior to rainfall events will be assessed. Several soil textures and soil water contents will be evaluated.
