Chaff cart

Not so long ago harvest weed seed control (HWSC) was only used by a minority of early adopting grain growers, now it has gone mainstream and pretty soon just about everyone will be doing it. Every few years GRDC fund a large grower practices telephone survey. The most recent survey was conducted by CSIRO in 2014, and they collaborated with Michael Walsh who at the time managed the HWSC program at AHRI (now at University of Sydney) to design the HWSC questions.
