A research project was conducted to determine how VOC emissions degrade with time after land application of swine manure slurry, and to determine how VOC emissions are affected by land application method (surface application vs. injection). Swine slurry from a pull-plug barn was applied to research plots. VOC emissions were measured using a small wind tunnel and EPA flux chamber. VOCs were sampled with sorbent tubes and vacuum pumps, and analyzed by GC/MS. First order exponential decay described most decay curves, but overestimated emission rates at 6 hr. Inject resulted in 90 percent lower emission rates for five phenolic compounds.
