Efficient grain production compared with N2O emissions locations

The main aims of this demonstration are to:

  • Increase farmer knowledge about the N2O emissions made from fertiliser and legumes;  
  • Reveal options available to reduce N20 emissions; and
  • Provide information about nutrient use efficiency to maximise productivity.
Key messages

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.
