Effect of Air-Flow Rates on Laboratory Measurement of NH3 Volatilization
Panchras, H. and Yusop, Mohd Khanif (1988) Effect of Air-Flow Rates on Laboratory Measurement of NH3 Volatilization. Pertanika, 11 (2). pp. 323-325.
The effect of air-flow rates on the volatilization loss of NH3 from urea was studied on two soil types. In both soils, the volatilization loss increased with increasing air flow rates up to 14 volume/min. Further increase in air-flow rate to more than 14 volume/min. did not significantly increase volatilization loss ofNH3" It is suggested that volatilization loss should be measured at an air flow rate of14 volume/ min.
