Sward height effect on emission of NH3 from broiler manure applied to Dactylis glomerata L .
Ammonia volatilization is a major N loss pathway from land applied manure.Strategies for reduction generally involve injection, incorporation or rapid infiltration of the manure.These techniques are often not available for application on perennial forages.Previous work has shown lower emission when liquid pig manure was applied in bands under a growing crop of winter wheat (Sommer et al.1997).This potential abatement method has not been examined for solid manures which cannot be injected into grass.The objective of this study was to examine the effect of grass height on NH3 emission from applied broiler litter.
