I've never eaten it, but the main reason I include it in the mix is for nitrogen fixation and pollinator food.

You can buy clover seed that's already inoculated with the symbiotic nitrogen fixing bacteria. Like this product. I'm hoping that will help get the soil life reestablished. I'll add a bit of this to jumpstart the soil ecology.

Looks like you can eat red clover, so that's good to know. I think I'd rather eat the purslane, amaranth, and dandelion for greens though.

I'll make them with one half heat sterilized red clay and one half finished worm castings, then mix in the seeds and mycorrhizae, and make little discs. Once they dry, I'll be able to toss them in suitable places and hope for the best.

Sorry if this is TMI. It's been on my mind.

It usually comes in the form of a powder you add to the soil at planting time. You can find it at garden centers (normally near the bean & pea seeds) or online, often marketed as "bean & pea booster" or something along those lines. I like this one, but there are lots of other brands out there.
