For all of the non-NJ natives, there's a reason why we're called "The Garden State,” so don't be surprised when pesticides show up in your soil analyses (and Pb & As), but now there's at least some current guidance on how to handle it. For a little historic reference, take a look at this article (and advertisements) from the May 1952, NJ Farm & Garden Magazine.
