| im tearing down a old patio deck thats concrete under the slab is nothing but dirt theres about a dump truck or more under there.is the dirt ok to use in my garden. thanks randy |
| If the soil in question has just been sitting idle for years it is probably depleted of all microbial life. You can use it in your garden if you mix some organic matter back into it to restore its natural balance. Best wishes with your garden. |
