Thanks for the info, both of you.  What I used in between the rows of potatoes 
under the woodchips is completely gone so I know it decomposes quickly.  I 
was very careful to not use any cardboard that had too much ink on it, drink 
flats mostly as they happened to be the right size.

I'll try to check for more info on chemicals.
