Need help picking soil

[Duets]

Hi, I just finished reading an article about what soil works best for tomatoes, it said to use 1/3 regular dirt or soil, 1/3 steer manure, & 1/3 like Miracle Grow for Veggies. Add peat moss if needed. Hope this helps. I currently am using only Miracle Grow for veggies, so far so good. I am in the process of adding the first mentioned above in my next batch of tomatoes planted.
