We have a very large, full-sun cement pad 20' x 30' in front of our shop, too much space to waste.
I four half-wine-barrels and four very large ceramic pots in which I want to grow vegetables, especially potatoes and tomatoes, maybe eggplant too.
What is best container soil recipe for growing vegetables. I need too much soil to buy it in bags, and plan on mixing our own.
Thanks in advance,

I have used MG 24-8-16 or 12-4-8, and Foliage-Pro 9-3-6 (all are 3:1:2 ratio soluble fertilizers) on tomatoes with very good results.
While plants are young, I fertilize frequently at half strength (weekly). As plants mature and have enough photosynthesizing machinery in place (foliage) I reduce the dosage and start adding a little ProTeKt 0-0-3 to the fertilizer solution. Alternately, you could simply include a little potash to the soil when you plant and use reduced doses of the fertilizer, or you could switch to a 1:1:1 ratio fertilizer like 20-20-20 after the plants have grown a little.
The idea behind switching to a lower N rate after the plant has some foliage is to reduce vegetative growth so plants will put more energy toward fruit production, rather than producing new leaves.
