Can I test my soil for effective rhizobia before I sow?
29 JulBy atadmin
Currently for the farmer there is not a commercially available test however an affordable fast turnaround method is being developed here in Western Australian at the Centre for Rhizobium Studies at Murdoch University. There is an established glasshouse based method which is reasonably reliable but it’s prohibitively expensive and takes up to 8 weeks to return a result.
For the next few years at least, reviewing rotation history and getting an understanding of factors that may suppress or delay the onset of nodulation or affect persistence of rhizobia in soils is currently the best gauge for assessing paddock or background stain effectiveness.
