Abstract

Ammonia emissions of both events were combined. Total losses of NH3-N from animal manures were low throughout if anaerobically stored and thereafter incorporated into soil. The largest reduction in NH3 losses from poultry excreta was achieved if the excreta were dried prior to storage and incorporated into soil. In contrast aerobic decomposition or composting of animal manures caused much higher NH3 emissions. Composting of animal wastes should be restricted to those that need to be hygienized.
