It's gotta be done through plants. The way it happens is still largely not discussed. You need three things:
1. Growing and diverse plants all season long (minimize spraying and tillage gaps)
2. Decent soil pH
3. Balanced minerals in the soil (only talking calcium/magnesium here, not NPK)
Even if you have all that, it doesn't get into your plant without soil biology. I like to use the analogy of eating a chunk of limestone. You might not choke. You may even be able to pass it without hurting your vent, but you won't get any calcium out of it. It's the fungus, plant root exudates, worms, etc that will eat and piss all over those rock particles and solubolize enough for the fungi to haul it back to the plant for uptake. Those fungi are the FedEx of the soil.
Every plant produces different root exudates (acids). Those acids, when squirted on a rock produce a reaction. This is why diversity is important. I can't recall how many plant root acids have been isolated, but they are numerous and key to what grows.
So make sure you have it, and make sure you've got the workers and networks to get it back to your plants.
