High-P chars,from manures,can have very high Ph, and CCE, high adsorbtion of heavy metals and other toxic chemicals making them biologically unavailable.

20 miles up river in Waynesboro,
I just got a call this week from DuPont, they are hot to trot for mercury remediation, I've sent them all the recent heavy metal papers and ISU presentations

Someone should also lay siege to the Pentagon, catapulting the ISU presentations on dioxins for a diplomatic coup-de-ta to do a large scale cleanup of 2-4D in Vietnam .

On this Appalachian restoration land-use model Solutions proposal, I would also cite the work below;
