dear friends....can't seem to locate an answer to this question in the national standards -
what currrent levels IN THE SOIL (ppm, etc.) of heavy metals (those associated with past and current use of agricultural pesticides/herbicides), organochlorides, PCB's and organophosphates, plus mercury, DDT...among others..........are allowed under organic certification.
NOTE: this is on behalf of Delta, MS farmers who hope to be certified but whose land, even when not conventionally farmed, has been sprayed and flooded for decades with ag cotton chemicals, or has been conventionally farmed in recent and/or distant past.....

I would suggest also asking in the SANET-MG forum where there are lots of professionals who are quite knowledgable in this area, some of whom may have had experience with analysis of soils for toxics and soil bioremediation as related to organic certification.
