Abstract

Moisture and urine were applied to a feedlot surface in a 2x2 factorial design. Forced-air wind tunnels were used to determine differences in the net flux of ammonia (NH₃) being volatilized. Surface DM, pH and surface temperature were all analyzed within each treatment to determine effect on NH₃ net flux. No effects of urine were detected. There were differences detected due to moisture and moisture*time with the dry plots releasing significantly more NH3.
