A short while back, July 20th, you sent out a request for information
on "decontamination" of soils.
If it is convenient I would appreciate copies of information you
received in response to your request.
I am currently working on a collection and database of materials on
waste management in agriculture. A big concern with using compost, and
especially that with municipal sewage included, is heavy metals. Plants
are less able to take up the metals when the pH is not acid, or between
6 and 7, which gives some ability to manage the situation.
I hope your research is going well.
