| Abstract/Contents: | "Ammonia (NH3) volatilization was determined from 15N-labeled urea applied foliarly in 35 ml-m-2 water at 1.7 and 3.4 g N/m2 to a 'Park' Kentucky bluegrass (Poa pratensis L.) turf that was grown on Sharpsburg silty clay loam (Typic Argiudoll). Field measurements of NH3 volatilization were made 1, 5, 9, 13, and 25 hr after treatment (HAT). Additional volatilization measurements were made at 2, 3, and 4 days after treatment (DAT). Maximum NH3 losses of 9.7 and 23.0 mg N/m2 per hr at 5 and 25 HAT occurred with the 3.4 g N/m2 treatment. Maximum volatilizaiton during 25 HAT coincided with periods of high leaf surface moisture followed by rapid drying. On the second day after treatment, the maximum NH3 loss of 14.0 mg N/m2 per hr occurred from 3.4 N/m2 treatment. Cumulative 4-day NH3 volatilization losses for foliar-applied urea at 1.7 and 3.4 g N/m2 were 35% and 31%." |
