Legume research to improve sustainable cereal rotations
THE NITROGEN benefit from different legume species in cereal-based crop rotations has been quantified by Western Australian research to help boost yields, reduce fertiliser costs and industry emissions.
The Department of Primary Industries and Regional Development (DPIRD) profiled the study at the Grains Research and Development Corporation (GRDC) Research Updates in Perth on Tuesday.
The research quantified the timing and magnitude of nitrogen release from decomposing legume stubbles and determined the extent to which this nitrogen was recovered by subsequent cereal crops.
The four year rotational trial, undertaken with GRDC co-investment and support from the WA Agricultural Research Collaboration, CSIRO and Murdoch University, was established in 2023 on duplex soil at Konnongorring, south of Wongan Hills.
The work evaluated nitrogen supplies from residue mineralisation (decomposition) of clover, serradella, lupins, Trigonella and woolly pod vetch.
