To compare conventional practice with an alternative pre-plant N fertiliser placement in relation to the irrigated furrow, to investigate the potential impact on soil mineral N concentrations and consequent N2O emissions.
The trial was harvested with a commercial six-row picker.
Randomised complete block design with three replications of three treatments. Each plot was eight rows (× 1 m) wide and 560 m long (paddock length).

| Acknowledgments |
This experiment was part of the project Determining optimum nitrogen strategies for abatement of emissions for different irrigated cotton systems (AOTG14013; 2013–17), with joint investment by NSW DPI and DAWR, and administered by CRDC. Thanks to Rod Smith for providing the experimental site and applying the irrigation treatments in field. Thanks to Wayne McPherson for field assistance. All soil and plant N analyses were carried out by Clarence Mercer, NSW DPI, at the ISO9001-accredited laboratory at Tamworth Agricultural Institute, NSW DPI. |
