Question

Can you concrete decking posts into the soil or should they be rested on the concrete?

Answer 1

As suggested so far, it may be dictated, or allowable at your choice. Certainly how you proceed depends on codes and zoning regs. among other issues.

   I happen to prefer pouring footers, at an appropriate depth for the weigh to support, the code issues, any frost line issues, and soil composition issues.

   I prefer Pier Blocks with a 4 x 4 bracket embedded, either a solid one, or an adjustable, allowing fractional leveling.

Answer 2

It is better to concrete a metal stirrup into the ground then attache the post to it. Otherwise if there is a lot of moisture around the post will rot. also if there is any white ants in your area they will easily get into the post through concrete

Answer 3

I pour a concrete footer with a metal post base.  Building code here (Colorado) does not allow to have posts set directly in the ground.
