Hello fellow gardeners,
Any rock dust gurus out there? I'm pretty new at gardening, and have definitely gotten addicted already. I'm reading lots of raves on the interwebs about rock dust, but haven't seen a mention of it in any of the old-school gardening books I've read. So, a few questions:
1. If my soil is already PAINFULLY rocky, is it likely I need any at all? Surely some of that stuff has already broken down into usable form, just based on sheer volume, no? It would be kind of ironic to spend most of my time eliminating rocks only to end up adding them back in in powdered form.
2. If I could still benefit from rock dust, will the dust from any rocks do, or are there certain types to look for? Because for every cubic foot of earth I till, I get like .75 cubic feet of rocks, so I'm thinking I could just bash them to bits. Good stress relief as a bonus.
3. I thought I had some more specific questions, but they're escaping me now, so just a general one: what are the benefits from rock dust, and are there alternatives? I've gathered just that they provide some of those "trace nutrients" that plants need beyond the standard NPK, but the details were lacking. I reckon crushed bones would supply some calcium, and Epsom salts some magnesium, etc., for example.
