Can you link to any of the work you've done, or any articles that explore similar ideas? I'm interested in reading more.

We've been using variable rate to tailor nutrient applications for a few years now[0], and have started contracting with a WeedIt to do spot spraying(major reduction in chemical application).

We've definitely discussed "reforming" some of our paddock structures to improve yield, or mitigate weed potential (sowing east-west vs north south). Although if you were going to commit to major production changes like that, you'd probably want to bundle them together. Changing sowing direction would mean restarting CTF, so you'd be best of doing another operation such as deep ripping at the same time.

We've experimented with wetting agents, as we have quite bad non-wetting soil, and the results have been quite good. It's amazing to watch the before and after[1]

Do you think we're going to need a shift in machinery before we can break out of conventional cropping patterns/methods? I'm still somewhat skeptical that a swarm farm type setup would work in our broad-acre situation, but I think a downsizing of machinery (1 * 60m bar -> 3 * 20m bar), could work if they also move to fully autonomous & electric drive. Although, automation for field operations is still quite "simple" compared to the logistics of managing seed/fert refils.

If you haven't already, you may wish to review Joel Salatin's work - he's based in the US, does a combination of broadacre and intensive farming, and has written many books. Some could be described as popular, rather than text, book style - I'm sorry I can't provide specific examples that may be appropriate, as I've only read a couple of his books and seen some interviews. He gained a fair bit of fame from featuring in Michael Pollan's 'The Omnivore's Dilemma' a few years back.

Do you use / have you used a Yeomans' plough, and/or investigated keyline? These are well suited to broadacre remediation and improvement (compared to, say, the details around inner zone planning of permaculture). I've seen evidence of these techniques around the Hunter, near Yeomans' original property, and the methods tend to be highly regarded.

>Keyline ploughs

I actually work as an engineer/designer for a small business based in Queensland who build ploughs, including non-inversion deep rippers (somewhat in competition with Yeoman). We have in the last ~8 months sold a heap of rippers into WA in partnership with a local manufacturer, targeting clay pan breakup, pH remediation, etc. with a lot of success. It's interesting the way deep tillage and other mechanical soil management ideas are experiencing something of a renaissance out west at the moment.
