The study of ammonia emissions from composting deadstock and other agricultural wastes has been a topic of great interest lately due to the concern of air quality impacts from the respective facilities. Previous deadstock composting research has shown that ammonia emissions are strongly affected by increasing the pile pH above 8. To verify these findings and ascertain the uncertainty in the data, a project was initiated to look at composting poultry deadstock while using different amendments within the pile and observing the effects on ammonia emissions.
