Abstract: Ammonia and hydrogen sulphide flux and dry deposition velocity were estimated using micrometeorological vertical gradient flux method at a commercial cattle feedyard of approximately 50,000 head of beef cattle and average 14.4 m²/head (150 ft²/head) stocking density. Ammonia-N and H₂S-S loss had general diurnal patterns with the highest fluxes in daytime and lowest fluxes in nighttime that correlated to temperature changes and active evaporation process during daytime. The highest average deposition velocities also occurred during daytime with unstable atmospheric conditions and the lowest during nighttime with very stable conditions. There are exponential relationship between NH₃-N flux and ambient temperature with R² = 0.57 for NH₃ (NH₃-N flux = – 1.46 + 7.96e^{0.077*Temperature}) and R² = 0.22 for H₂S-S (H₂S-S flux = – 0.75 + 0.8e^{-0.013*Temperature}).
