GRDC Code: UWA2202-001RTX
Quantifying nitrogen losses and the effect on crop productivity and greenhouse gas emissions from the application of lime and sulphate of ammonia fertiliser under Western Australian farming systems.
There has been grower and industry concern of significant nitrogen losses causing loss in productivity from the application of sulphate of ammonia (SOA) and calcium carbonate (lime) in close sequence within Western Australian farming system. Concerns have also been raised around the contribution this practice has on increasing GHG emissions intensity from these systems.
