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.
