New soil for next year?

I'm probably going to use fox farms ocean forest next year for my outdoor grow. Would it better to use Fox Farms Happy Frog High Phosphorus Bat Guano Fertilizer? I know i can buy it closer so i was wondering if it would work?

one of those products is soil and the other is fertilizer...

oh, wow i just notice that...

Why not make you own soil or soil less mix?
