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.

Short black, long black, double shot, double break? Coffee preference is a little like crop sequences. Perhaps you’re a ‘short black’ wheat-canola type, strong on inputs? Or a ‘long black’ type who likes to dilute their rotations a bit more? Or are you a ‘double shot’, throwing in a few break crops in a row for maximum effect? Hear from Tony Swan in this podcast on the key findings of the research on double breaks.
