Thank you for this excellent piece Kevin. Incidentally, I've been using rock dust for 20 years or more on my veg beds and I'm very happy with the resultant fertility and crop health. Nevertheless, I am intrigued and receptive to the counter argument from some soil microbiologists and regen farmers that rock dust may be a bit of a distraction, and a costly one, in certain contexts - given the ability of healthy soils (in healthy diverse ecosystems) to mine rock in the subsoil extremely effectively. As you point out fungi are central to this mineral mining process and delivering those minerals in soluble form to plants at the rootzone.
Thanks Simon!! Appreciate the kind words - what rock dust do you apply? Curious for my own experiments.
I didn’t include it in the article, but the sweet spot of warm, humid climates like Brazil and India seem to have the most potential for carbon storage with enhanced weathering , but I think the ag implications need to be as strong a use case. It’s an incredible tool to have in our belt in any case!

Hi Kevin, I use rockdust from SEER - Cameron and Moira Thompson's pioneering business in Perthshire. Best, Simon
