Harvest weed seed control adoption survey
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.
This is the result from a national Australian GRDC grower survey reported in a recent scientific publication by Michael Walsh from University of Sydney. 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 to design the HWSC questions.
The survey revealed 43% of Australian grain growers are currently practicing HWSC and this is set to rise to 82% within the next five years. Narrow windrow burning is currently the most commonly used practice by 30% of growers.
Jessica Strauss speaks with Peter Newman about the paper findings.
