The more I see about cover cropping being toyed with in Australia, especially via Twitter.com, the more I feel redundant, as if “my work here is done”. And anything else I can add will verge on rambling, when there plenty of growers having a go, sowing paddocks with CC mixes, and publishing results with photos and captions. Maybe they were doing so a few years ago, but I wasn’t seeing it in my Google searches, or it wasn’t getting published.
So, to help things along, if you want to learn more now, I suggest you get yourself on Twitter, and start following and reading. For a start, search for (in no particular order): https://twitter.com/FreddoMorgan
Also, simply do word searches: cover crop, covercrop, #covercrop, #tillageradish #rootsnotiron etc. With and without gaps, the hashtag (#), singular and plural. You will end up finding growers, agronomists, seed merchants and researchers having a crack. You will discover permies and gardeners, Poms growing feed for deer, pheasant, quail etc, Yanks being mandated to cover their soil in winters to stop erosion into streams and lakes, and getting subsidised for it. You will find unusual uses for common and obscure species of plants getting used for cover crops. Get down that rabbit hole and enjoy. (Sleep is important, remember).
You could also search for mentions of the gurus who are not on Twitter: eg Gabe Brown, Dave Brandt, Rick Bieber, Jay Fuhrer, Elaine Ingham, Rolf Derpsch, remembering to use “” marks to help search for names, like a phrase. You might find more links to talks on Youtube, or written articles. Or Nuffield Scholars. Another rabbit hole.
Should I keep this up? I see a future in the CC practice in Australia, and with it a seed industry. It is already happening: AGF seeds at Smeaton, Vic, is distributing Tillage Radish ™ and mentioning sunn hemp. Any number of NSW & Qld seed distributors are supplying tropical species which are appropriate for southern growers in the summer. Field days and crop walks are already happening to see what is happening in different rainfall zones.
I’ll just keep asking the hard questions and bouncing ideas.
