Abstract

Laboratory trials were conducted to measure the dissociation and mass transfer coefficients for ammonia volatilization from buffered ammonium-water solutions and dairy cattle manure. Effects of ionic strength, ammoniacal N concentration, temperature and pH of the media, and air velocity over the media were evaluated. Current models were found to adequately predict ammonia emissions; even though, important differences were found in measured and model- predicted dissociation between ammonium solution and dairy manure. The results imply that model refinements can be made to improve accuracy in predicting emissions from livestock manure.
