Acknowledgments |
These experiments were 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 Cam Geddes and Rod Smith for providing the experimental sites and for applying the N fertiliser treatments into the required plots, and to Amanda Noone and Wayne McPherson for field work at Emerald and Gunnedah, respectively. All soil and plant N analyses were carried out by Clarence Mercer at the ISO9001-accredited laboratory at Tamworth Agricultural Institute, NSW DPI. |
