Why do garden plants usually grow better in topsoil than in subsoil?

hi there

your answer to this  response is

It's usually darker in color than the subsoil since it contains more organic matter from decaying plants and their roots. It is  more fertilize than subsoil, due to having more organic matter and because fertilizers are usually added to the topsoil only.

i hope this helps you out :)

have a great afternoon
