Synopsis: No appreciable ammonia volatilized when less than 100 pounds of nitrogen per acre as urea was topdressed on soils with pH values below 6.3. Large ammonia losses took place when higher rates of urea were surface-applied to bare soil and when soil drying occurred shortly after urea application.
