Making Soil

Hello!

I live in an area with high levels of lead contamination in the soil. As a result, it is possible I will not be able to use any of the soil in my yard for my garden. I know there is debate on whether plants grown in leaded soil are dangerous, but I'd rather be on the safe side. So, I'm going to have to import soil for my garden, and as consequence will be going with raised beds.

So I have two questions - 1.) If I mix some humus, some vermiculite and some peat moss together is that "soil"? Or does there need to be something else? The gardening books I've read talk about using those substances to amend soil, not to replace it altogether.

2.) Raised beds - are they supposed to have a bottom? My husband says no, but how are you supposed to isolate the roots from the lead if they grow through the new soil into the old?

I would really appreciate any help people can give with this.

Thanks!
