I've been growing a vegetable garden for a few decades now and i never stop learning how to get better return for my efforts. Adding Micro-nutrients is important to sustain garden soil over many years of use. One of the ways to get this into your soil is to add Rock Dust. Thinking I could make this fairly easy in the Tumbler but it may take a while. Crush up a wide variety of stone and put it in the tumbler with a few large stones to help crush everything up.
Just tumble the raw rough rocks in a large tumbler without any grit and a small amount of water. When doing cleanout, filter the slurry through window-screen and add to the garden as-is or dry it out and add it as a powder. Repeat as Necessary . . .

Wooferhound I see you are from Huntsville. Then if you want natural nutrients for your garden then go to MS and collect the glauconitic clay/soil from the Ripley formation. This is high in P and from a geologic paper I found from the 1800s it works better than commercial fertilizer.

Good thread. I thought about grinding up some of the little chips of apatite that I have hanging around. I changed my mind and just tossed them into the veggie garden as-is. They will break down on their own over time. My own little Magic Grow.

Enhanced silicate rock weathering (ERW), deployable with croplands, has potential use for atmospheric carbon dioxide (CO2) removal (CDR), which is now necessary to mitigate anthropogenic climate change. ERW also has possible co-benefits for improved food and soil security, and reduced ocean acidification. Here we use an integrated performance modelling approach to make an initial techno-economic assessment for 2050, quantifying how CDR potential and costs vary among nations in relation to business-as-usual energy policies and policies consistent with limiting future warming to 2 degrees Celsius5. China, India, the USA and Brazil have great potential to help achieve average global CDR goals of 0.5 to 2 gigatonnes of carbon dioxide (CO2) per year with extraction costs of approximately US$80–180 per tonne of CO2. These goals and costs are robust, regardless of future energy policies. Deployment within existing croplands offers opportunities to align agriculture and climate policy. However, success will depend upon overcoming political and social inertia to develop regulatory and incentive frameworks. We discuss the challenges and opportunities of ERW deployment, including the potential for excess industrial silicate materials (basalt mine overburden, concrete, and iron and steel slag) to obviate the need for new mining, as well as uncertainties in soil weathering rates and land–ocean transfer of weathered products.

I have been dumping much of my used slurry into my garden for years and I think it helps. There's a local company in Utah who grinds up volcanic cinders into a powder and sells it as garden supplement for mineral replenishment and they have a loyal following.
