The main aims of this demonstration are to:
Although the N2O emissions did not seem to correlate with the rate of N fertilizer applied the demonstration did clearly show that despite extremely wet conditions at and soon after application N2O emissions are still relatively low (less than 10%) compared to irrigation sites. These emissions are likely to be well above average in this soil and rainfall indicating the emissions from N2O in these cropping systems is relatively insignificant. The demonstration will be conducted again in 2014 using several rates of Non a single soil type to get a clearerpicture of the variation in emissions.

In 2012 BCG, in conjunction with DAFF, the Department of Primary Industries (DPI) and the Low RainfallCollaboration Group (LRCG), managed two demonstrations that measured N2O emissions from soils under varying cropping regimes. The first compared the N2O output when N was applied through synthetic fertiliser. The second measured the N contribution made by a vetch legume crop that was terminated at various times in the establishment year. The corresponding effect of N2O emissions from a& |
