The objectives were to:
1. reduce nitrous oxide emissions from dryland grains cropping.
2. improve nitrogen use efficiency.
3. validate and develop process-based biogeochemistry models.
4. simulate net greenhouse gas emission under current and projected future climate scenarios.
The experimental design was a randomised split-plot design with tillage (tilled vs. no-till) for the whole plot and nitrogen rates (0, 20, 50 and 100 kg N/ha) as subplots in 2012 (year 1) and 2013 (year 2), or legume types as subplots in 2014 (year 3).
