Hi all,
My local community garden had some soil delivered by the city, but
there is some concern about the potential that the soil is not safe to
grow edible plants.

Is there any reliable way to test if soil is appropriate to grow
edibles? My local extension school offers lots of nutrient and
biomass tests, but I don't see anything about testing for
contaminants.

I realize that the pool of potential contaminants in soil is
inexhaustible. However, what would people recommend as basic
precautions.

Thanks,
Tim
