Abstract
Ammonia (NH3) volatilization from artificial urine applied to perennial ryegrass (Lolium perenne L.) pastures was measured during the grazing season of 1986. The amount of NH3 volatilized in 10 days after application ranged from 7–12% of nitrogen (N) applied at a urine-N application rate equivalent to 285 kg N ha-1 and from 4–18% for an application rate of 600 kg urine-N ha-1. Depending on the experimental conditions, 0–45% of the N applied was not recovered, suggesting high N losses by other loss pathways.
