lupin wheat rotation

Catalogue: GRDC Final Reports
Field measurements and lifecycle analysis (LCA) in this project examined if CO 2 emissions from urea could be reduced by substituting urea with grain legume-fixed N and if soil N 2 O emissions could be reduced by raising soil pH (through liming)... The extent to which incorporating grain legumes in cropping rotations would reduce emissions depends on the amount of urea that was saved by substituting grain legume-fixed N for synthetic N fertiliser... The first aim of this research was to measure N 2 O emissions in the field for two years and incorporate the findings into a lifecycle analysis (LCA) to determine if incorporating a grain legume (lupins) into a cropping rotation would lower on-farm and total GHG emissions from wheat production...

Timely application of N can improve yield and protein of a wheat crop (Hill 2005)... The use of precision sowing to plant into the ridge of the previous season will influence crop behaviour... It is suspected that the application of results from this trial may be limited to the deep sandy earth sand plain soils in the medium rainfall zone...
