I was reading the posts regarding the situation in Mercersburg.  I work with farmers and unfortunately this is an all too common senerio.  However there are many out there that do respect the history on there land.  I can tell you that when ever there is a conservation plan done on a farm paper work is filled out to document such items on the farm through a "Cultural Resources" Worksheet and it is is forwarded to the PA State NRCS Office for review.  If there is a concern it is forwarded over to the PA State Historical Commission.  Farmers are not technically allowed to do anything that will impact the historical significant of what is on there land.  There are laws on the books and this is the reason they are there.  Has anyone reported this to the 1) local historical society? 2) PA State Historical Commission?  Here's also some info regarding the cemetery laws that are on the books in PA.  http://www.pa-roots.com/index.php/saving-graves   There is a link at the bottom to get this cemetery on the endangered cemetery list. If the planting just occured on this farm it was not soybeans that was planted.  It would of been a grass, alfalfa, or small grain. Amy
