Nitrogen applied to turfgrass stands can be lost through leaching, denitrification, or ammonia (NH3) volatilization. The purpose of this investigation was to evaluate the effects of N carrier and mode of application on NH3 volatilization from a Kentucky bluegrass (Poa pratensis L.) turf growing on an acidic (pH 6.4) Flanagan silt loam (fine, montmorillonitic, mesic Aquic Argiudoll) soil. The NH3, which volatilized after application of any of several sulfur-coated ureas (SCU), prilled urea, spray-applied solubilized urea, and two liquid N products was measured by passing the airstream from microecosystems, in which the treated turfs …
