Reducing Ammonia Levels with Liquid Alum

The use of high-acid liquid alum as a litter amendment has the potential to greatly reduce ammonia levels and emissions from broiler production facilities, according to the results of a NIFA research grant. The application of liquid alum at all three treatment levels was found by University of Tennessee researchers to be very effective at reducing in-house ammonia levels, as compared to no alum application.

By the third week following application, the ammonia reduction in the treated houses had ceased. The research study will be continued for an additional five grow-out periods to provide complete treatment replication in time over both summer and winter months.
