Research into cutting nitrogen bills
June 23 2010
THE production of wheat and barley varieties which can access and use nitrogen more efficiently could cut farmers’ fertiliser bills while reducing environmental damage from fertilisers leaching into the soil, especially in sandy areas.
A recently started five-year Grains Research and Development Corporation (GRDC) funded project has been set up with the goal of developing more nitrogen efficient varieties through a process of assessing genetic variability in nitrogen use efficiency in Australian wheat and barley germplasm, including advanced breeding lines.
The project involves researchers from the University of Western Australia (UWA), the Department of Agriculture and Food WA (DAFWA) and the University of Sydney, with contributions from major Australian breeding companies.
UWA researcher Winthrop Professor Zed Rengel said high fertiliser prices were driving the development of new cultivars better able to acquire and use nitrogen.
“Modern grain production relies on relatively large amounts of synthetic fertilisers to...
