Companion and intercropping piquing interest of Aussie farmers
April 22, 2020
Today on the podcast we’re doing a special on intercropping and companion cropping.

Before we get into it, here’s what both intercrops and companion crops are:
Intercrop: where two or more species are sown and harvested together with the objective to harvest the grain of both species.
Companion crop: Where two or more species are sown together with the objective to harvest the grain of a single species. The other species are either grazed out or terminated using herbicides.
We hear from CSIRO Farming Systems Scientist, Dr Andrew Fletcher. He tells us about the potential role of companion and intercropping in Australian grain farming systems. Andrew also recently presented this topic at the Perth GRDC Updates, which has sparked interest in this space in Australia.
We also hear from farmer Murray Scholz, who has a mixed farming operation in the Southern Region in Culcairn NSW, which is halfway between Wagga Wagga and Albury. Murray has been on the podcast before, talking about his use of disc seeding. So, thanks to him for coming back!
And finally, we hear from WeedSmart Southern Extension Agronomist, Greg Condon. He gives a detailed overview of companion and intercropping in his region and explains some of the quirks to how it all works.
