Hi all. I'm new to the forums. Hope someone can clear something up for me! I'm a total rookie when it comes to gardening... So please take it easy on me.

I just moved into a new apartment in Brooklyn, NY with a decent sized yard. Behind my yard, there's a small junk yard. Do I need to worry about my soil before starting to plant veggies? Could there be oil or other contaminants in the soil that would make the veggies or fruits dangerous to eat? Do I need to test the soil? If so, how is that done? The junk yard is kind of up on a slope so I worry that the cars could of been leaking or are leaking something that is coming down into my yard.

If any of you require pictures , let me know! I'll post some!

Thanks so much!!!

Jaime
