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 CSREES
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.
