several other references on this topic:
Levinson, A.A. (1974) Introduction to Exploration Geochemistry. Applied
Publishing Ltd., Wilmette, Illinois, U.S.A.
--- this book has a section on the use of vegetation surveys (that is
where veg. samples are analyzed for their chemical content). The idea is
that some plants concentrate particular elements above what would be found
in the soil. Also, a tree's root system "samples" to a greater depth than
could be done by digging a soil pit.
A book by Brooks that might be a bit easier to find than the article
listed by the previous poster:
Brooks, R.R. (1972) Geobotany and Biogeochemistry in Mineral Exploration.
Harper and Row.
Hope this helps.

The New Alchemy Institute ceased functions in 1991 due
primarily to financial problems. Just recently, New
Alchemy publications have become available through a
group of former New Alchemists who still live in the
area. The Green Center can provide a list of for-sale
Talk about a history of appropriate technology and
alternative agriculture, New Alchemy's publications still
provide a decent introduction to aquaculture systems, composting
greenhouses, bioshelters, cover crops for the Northeast, etc.

Re: ecological fishfarming. Some of the most advanced
models of water purification and sustainable food production
are the 1) solar aquatic ponds (pioneered in part by
John Todd, formerly of New Alchemy) that use plants like water
hyacinth to purify waste water and 2) recirculating hydroponic
systems in which vegetable beds are fertigated with
effluent from tilapia aquaculture.
