NITROUS OXIDE EMISSION FROM FARM DAIRY EFFLUENT APPLICATION IN GRAZED GRASSLAND

Intensification in dairying and increased production of farm dairy effluent (FDE) has raised concerns about gaseous nitrogen (N) losses and their environmental implications. This study was undertaken to monitor changes in mineral-N and soil water-filled pore-space (WFPS) in relation to N(2)0 emissio...

This study was undertaken to monitor changes in mineral-N and soil water-filled pore-space (WFPS) in relation to N(2)0 emission from application of FDE to dairy-grazed pasture.

Total amounts of N(2)0 emitted from FDE application for first and second irrigation were 2% and 4.9%, respectively, of the total N added through effluents.
