I'd add that if it's food then just hydroponics or some other farming methods that uses less soil. If you're creating soil for grass for scenery or wildlife then I suggest hydroponics anyway to generate plant matter or aquaphonics especially so the fish could be both a protein source and the bacteria fish-shit filled wastewater be used in producing a liquid solution for soil. Anaerobic bacteria especially grows exponentially. In fact, if you're going into space in some o'neill cylinder then wouldn't you specifically breed plants that survive better in the first place? You'd do bazillion experiments on earth and space stations or lunar cities in the first place to get plants that grow well there. With how fucked up uc earth is becoming environmentally, it's likely scientists will be creating plants that grow in crap soil anyway because the deteriorating environment.
