Manipulating Bedding Materials and PLT super(TM) to Reduce NH sub(3) Emissions from Broiler Manure

Various aspects related to manipulating bedding materials and PLT super(TM) to reduce NH sub(3) emissions from broiler manure were discussed. Treatments were incubated for 11 days at 25 degree C and 98% relative humidity. Ammonia was trapped in 0.1 N H sub(2)SO sub(4) and measured colorimetrically as NH super(+) sub(4), and CO sub(2) was monitored with an infrared analyzer. The research on manipulating the C/N ratio of broiler litter showed that bedding materials namely wheat straw, wood shavings, and sawdust with C(total)/N(total) > 50 or C(biodegradable)/N(total) > 40, had low NH sub(3) emissions. Peanut hulls exhibited high NH sub(3) volatilization because they had low C/N ratios. PLT super(TM) decreased pH, NH sub(3), and CO sub(2) emissions during a two weeks incubation study. No significant interactions on NH sub(3) emissions were detected between PLT super(TM) and bedding materials.
