A cropping trial with a climate change theme was recently undertaken at the UWA Future Farm 2050.

This trial aimed to demonstrate the effect of crop management (rotation/crop sequence and fallow) on emissions of nitrous oxide and the conservation of soil water for subsequent wheat crops.

This trial, UWA National Adaptation and Mitigation Initiative (NAMI) project, led by the Western Australian Department of Agriculture and Food (DAFWA), was funded by the Australian Government Department of Agriculture, Fisheries and Forestry (DAFF) and the Grains Research and Development Corporation (GRDC). Results so far have shown that previous crop management had no significant effect on nitrous oxide emissions in the following wheat crop. Rather, these emissions appeared to be impacted by the current crop management (seeding and fertilisation) and rainfall.

Most soil water was conserved in the chemical fallow in the previous year, although by seeding time there were no significant differences in amount of soil water at one of the two sites. The weedy fallow and wheat had the least soil water at seeding of the following wheat crop.
