Interesting piece here from the Australian Broadcasting Corporation on the rise of "biological farming" down under. It's all about growing healthy microfauna. This is something like what farming will be when we have a firm grasp of the genetics of invisible ecosystems:

"And you can just see the soils becoming, its flocculating better, the worms here are just going silly. That's all worm casting there you can see so rather than give this plot a rest you've just kept the growing activity going as much as you could." [farmer Cam McKellar said]

"We've found these beneficial fungi trichoderma they're called, we found higher levels of trichoderma in soils following break crops of canola compared to other break crops like chick pea and this was associated with lower levels of crown rot and higher yields in wheat following canola," farmer John Kirkegaard said.

[Thanks, Luke!]
