Forget copper tape, ask your local hair dressers or barbers for their chop off hair.
This is like barbwire on the slugs and will break down in the soil as well. With regards to heavy clay soil. If you know anyone who has a wood burner, get the wood ash and fine grit and spinkle it on the soil. Use garden compost as well and when its not too dry dig it over. If you dont want to plant anything in it this year grow green manure over it. I use red clover and once the plants have flowers just dig it all into the ground. Over the years this soil will get better if you do this every Oct - January.
