Potting Soil Recipes?

Potting soil for vegetable starts, herbs, shrubs, and trees. I usually use some mix of rabbit manure, woods litter, peat moss, compost, and/or topsoil. I like to make it myself so I know what's in it. We go through about a yard a year, and that's going to triple or more in the spring.
For seed starting soil, I like to use an aerated compost. So something like 50 percent composted manure/50 percent peat moss. For a more potting sort of soil, I like to add topsoil and some rabbit manure. In bigger pots (1 gallon or larger), I like to add some leaf litter, bits of straw or twigs, or maybe a few wood chips to feed the soil. Trees and shrubs seem like drainage is mor important to them, so probably a mix os topsoil with some compost.

I'd like to get away from buying peat moss. The coir stuff is too expensive for my operation. Maybe some hammer milled straw or old leaves would have the same effect as the peat? What would you use in a potting soil? I have pig, rabbit, and chicken manures as well as compost, straw, grasses, biochar, and woods litter to choose from. These soil blends will be used for my annual spring plant sale. I want it to be decent on the senses, and also to be sustainable, clean, and beneficial to the soil wherever my plants get rooted.

Have you tried Dr. Bryant Redhawk's formula for making potting soil?

My potting mix is 1/3 sharp sand (I have a lot of blasting sand left over from a project) 1/3 composted stall and coop clean out manures and 1/6 regular compost (leaves, grass, twigs, pulled up vegetable stems) and 1/6 soil from my forest area, to this mix I add 1 cup of sea-90 for complete mineral availability for the microbiome that is in my mix.

I make it different each year based on whatever I have going on and left over, but basically: sandy loam, compost, vermiculite, and peat moss or coco coir -- maybe in equalish proportions.

How much sand do you like to use, and what are you potting into it?  My pots are mostly all quarts or gallons and I sell young trees and vegetable starts.

The soil here is sandy loam. Some of that goes into the wheelbarrow when I'm mixing up a batch of potting mix, roughly equal parts to the other stuff.

I use it in random plastic, wooden, and clay vessels for various things --  sometimes with a layer of just vermiculite on top for starting tiny seeds. I use it in tiny starter pots that fit 72 into a 1020 tray. And I use it in quarts where I start fruit trees from seed.
