Soil conservation experts are usually in USDA Soil Conservation Service or state agencies. EPA is more geared toward contaminants. If that's what you have in mind, I work for a state agency and deal with soil contaminants all day long. Glad to be of assistance if I can.

Tox, would you mind following me so we can connect? I can be brief, if ya need. I may only need to be pointed in the right direction.

OK. I clicked the Follow button - first time I've done that here. I hope it doesn't launch the missiles. :-]
