Ihave to ask you a question, what is your opinion on trace minerals, basalt or azomite to work into soil? I'm still trying to learn and this is my last purchase until I'm ableto use all the other stuff I already have.
I haven't reached a conclusion on this yet, but I suspect we could get our mineral part of the mix simply by adding a few handfuls of the next best soil we can dig into (as long as it's not anaerobic or heavily fertilized, we don't want to be introducing unwanted elements that could cause havoc in our mix - whereby, with a really good microbial herd, they could handle that too).
Basically I think we're all completely confused by the chemical-think of the past 60 years, and the fear of scarcity it generates in our bones - and I totally count myself in with the crowd on this and keep stumbling over it!
Plus of course there is environmental devastation, which forces us to doubt the integrity of any inputs where man has been actively influencing.
Stories of people telling me how alpine herbs no longer have the healing power of former days - no agriculture up there beyond light sheep or cow grazing, along with some maintenance to preserve the cultivated ecosystem that has arisen over the ages of this mode of alpine land use! Up there, damage is being done by the mere settling of pollution dusts we're blowing into the air...
I opened an Instagram account recently to see how Mountain Organics is faring with his system (the system I'm leaning on to get my soils going), and LO! He's skipping just about all the amendments he used to recommend, depending mainly on his compost to have the right microbial profile, and mulching plant material back to the soil.
My opinion: yes! That's exactly where I want to head myself!
But you can only pull that off with a really good compost, and finding a trustworthy source (or taking the time to learn and make our own, with all the conundrums on inputs coming back boomerang style to haunt us) is the core issue.
But the reason I'm mentioning it: he makes the mineral portion of his mixes with volcanic rock dust along with pumice for aeration
Here's his recipe along with his reasonings:
Here’s the mix I used and this amount fits a 100gal pot perfectly.
4 cuF compost (@malibucompost )
3cuF CSPM (peat moss)
3 cuF pumice (lava rock) —— alternative: 4cuF
1.5 cuF biochar ——-alternative: .5cuF
40lbs rock dust (volcanic)
Worms (10 worms, 100 worms or 1000 worms, add more if you want them to turn your soil over (improving it) quicker, or add less if you don’t mind taking the slow road).
First thing you’ll notice is the lack of traditional ‘amendments’ which I think the industry has exemplified well beyond their importance for no other reason than to sell you yet another ‘thing’ that you MUST have and add to that organic gardeners (cannabis and otherwise) to a certain extent like to give ‘magical’ qualities to this or that amendment telling everyone that “X” amendment is their secret weapon and makes their product ‘the best’.
Well, it’s all bullshit you see, the real magic is in the quality of the humus/compost and the diversity of soil LIFE it brings to your potting soil mix and in the MINERALS aka degraded rocks aka ROCK DUST because that’s the backbone of soil, of life, that is where ALL soil nutrients originate from that are now cycling within plants and animals and our food and plant medicine supply - ROCKS and MICROBES.....an additional handful of alfalfa or neem or kelp or crab shell or comfrey or insect frass or bat shit or friggen feather, bone, or blood meal isn’t going to make or break your soil one little bit. Somewhere along the line we’ve minimized the importance of HUMUS (aka ORGANIC MATTER aka COMPOST/CASTINGS) and ROCKS (aka MINERALS aka ROCK DUST) and increased the importance of a laundry list of random ‘designer amendments’ which is just all backwards.

Nothing more to be added to that!
He's showing amazingly healthy and beautiful plants growing in no-tills on their 22nd run btw lol
So since I'm not going to start recommending the hillbilly-handful of random soil approach until I have done that myself, I don't see any reason not to use those rock dusts as a sand-silt-clay replacement in the meantime.
I forget which, but the one or other input in that "department" has problems like hi aluminum content and such, at present I tend to counteract such potentially negative effects simply by input diversity, i.e. small amounts of different inputs vs. relying on a single input, and not worry too much about it elsewise.
Hoping that's not totally offtopic to your question!
cheers!
