Question
I am looking for a homemade recipe for something that will permenantly kill grass and any vegetaion. So, in other words, something easy and deadly (towards plants). Thanks,
Kurt.

Answer
Permanent, as in, Forever?

Or Permanent, as in, a Lifetime?

Or Permanent, as in, as long as I live here?

I take it concrete doesn't work for you?  I had a question like this last year from a guy in Australia.  He was into Permanent/Forever.

And so, Kurt, I am pleased to advise you that since you want to do this easy, and you are looking for deadly, you accomplish your objectives with NO CHEMICALS.  So while it is deadly for vegetation, it is completely safe for you.

Plus chemicals are not the cheapest way to do it, anyway.  

Just want to make sure I get this right - Permanent?  Because sometimes people say things they don't exactly mean literally.  So we are talking "permanent" as in "forever"?  "Never" as in "'til Hell freezes over"?

So, to solve this problem in a way that will not damage God's earth, we can go to ancient times.

Check the Wikipedia description of the term "salting the earth"
www.answers.com/topic/salting-the-earth?hl=scorched&hl=earth&hl=policy

Wiki tells us this refers to and I quote 'the practice of spreading salt on fields to make them incapable of being used for crop-growing.'  This was done in ancient times during various conquests 'as an extremely punitive scorched
earth tactic.'

Wikipedia reminds us: "The Red Army also salted Soviet fields as a part of the scorched earth policy against the Nazi invasion. It was reported that when the Soviets reclaimed the territory, they were equally unable to use it."

Salt will solve your problem here, sir.

Salt (Sodium Chloride) reaches toxic levels dissolved in water.  Sodium ions displace Phosphorus and Potassium in your garden.  Plant roots take up Chloride ions and ship them around to all the leaves; there, they interrupt the manufacture of Chlorophyll, the roots suffer from severe dehydration, and it's Good Bye and Good Luck.

Acid loving plants are especially sensitive to salt and are the first to kick the bucket - that's Brooklyn English for "die".

Salt is not COMPLETELY permanent.  Neither is Nuclear Fallout.  However, the damage is as permanent at least as civilization.  Concrete is less permanent.  Certain weeds grow through concrete. You can cross that bridge when and if you come to it. Salt is easier and utterly fatal.

Any questions?
