Sorry for the slow reply - I was hoping someone else would answer you, as I knew I had his card SOMEWHERE!  I finally found it, so since no one else has supplied the information, here it is:  The Dept of Agriculture Soil Scientist is David Rocque.  His email is david.rocque@maine.gov and his phone number is (207) 287-2666.  Hopefully this information is still valid, as I got the card from him some time ago.
