The AGFACE project commenced in June 2007 at Horsham (3645′07″ S, 14206′52″E; 127m elevation), Victoria, Australia. Its aim is to quantify the interactive effects of elevated atmospheric carbon dioxide concentration (e[CO ]), nitrogen, temperature (accomplished by early and late sowing times), and soil moisture on the growth, yield, and water use of wheat (Triticum aestivum L.) under Australian conditions. The main engineering goal of the project was to maintain an even temporal and spatial distribution of carbon dioxide (CO ) at 550mol/mol within AGFACE rings containing the experimental treatments. Monitoring showed that e[CO ] at the ring-centres was maintained at or above 90% of the targe..
