This study investigates the changes in ammonia fluxes, pH and total nitrogen of liquid ferrous sulfate-treated litter over 5 weeks. A total of 200 broiler chicks (Arbor Acres, 1 d old) was separated into two treatment groups (0 g and 100 g liquid ferrous sulfate/kg litter) with four replications of 25 birds in each group. Liquid ferrous sulfate was sprayed on the litter by using a small sprayer. There was no difference (p>0.05) in the ammonia fluxes observed between the control and liquid ferrous sulfate treatment groups at 0, 1, and 5 weeks, except for 2, 3 and 4 weeks. At 5 weeks, the litter pH and total nitrogen content did not show any difference (p>0.05) between the control and liquid ferrous sulfate treatment groups. In conclusion, the use of liquid ferrous sulfate is not a suitable for use in poultry litter to reduce ammonia and pH or improve the total nitrogen content.
