Project details
Status: Current
Impact of waterlogging
Waterlogging impacts crop production in many parts of southern Australia, especially in the high rainfall zone of Victoria and Tasmania.
Experimental treatments
The research team will conduct experimental treatments using diverse cultivars of barley, canola and faba bean to examine the severity and duration of waterlogging-related anaerobic stress.
Algorithms will be developed to predict the effects of waterlogging on the growth, development and yield of these crops, along with information about the benefit and cost of mitigation.
Accelerating recovery from waterlogging
By 2026, the team aims to identify practices to accelerate recovery from waterlogging, such as crop nitrogen management. They will also recommend scenarios to avoid severe waterlogging and quantify the costs and benefits associated with these practices. This may include early sowing to deplete soil water, along with engineering and tillage solutions such as raised beds and drainage.
The algorithms developed through this research will be incorporated into the Agricultural Production System sIMulator (APSIM), which is a comprehensive model used by researchers and underpins decision support tools used by growers.
