- Abstract
The article reports on the impact that the banding of urea has on the volatilization of ammonia (NH3) in a dry, acidic soil. The application of urea contributes to the formation of smog and ecosystem degradation as a consequence of NH3 volatilization. Researchers employed wind tunnels to measure ammonia volatilization following the release of urea using various techniques including broadcast, broadcast and incorporated, and incorporated in shallow bands. Also examined were the volatilization effects of urea supplemented with a coated polymer or a urease inhibitor broadcast on a soil surface. A brief overview of the study results is presented.
