Grow your own, do you mind if I just call you Grow? I think you missed my point. Of course a basic soil test doesn't cover contaminants no matter whose doing the testing. I've used Cornell to test for some specific metals for an additional fee but I really don't know the range of testing they offer. If UC Davis does offer a wide range of tests I figured it might save our friend Stephen some money, if they don't and other landgrant universities don't, I'd like to know about it. I welcome your input to this specific question, Grow.
