  Fruiting crops are generally less prone to lead uptake than root crops or
leafy vegetables.  However, if the lead level in the soil is very high,
the crops might still contain high levels of lead.

  The U Mass Agricultural Extension tests soil for lead in addition to
testing for NPK and other nutrients.  The total cost for all the tests
is $7.50 per sample.  They also analyze plant tissue for lead, at a cost
of $10.  Try calling your county Extension Agent (should be listed under
the county government, in the phone book), for details of the procedure
in your area.

NOTICE TO MEDIA

The Coalition for a Green Economic Recovery will hold a conference October 1 to
3, l993 to discuss and promote the economic andenvironmental advantages of
living machines.  Living machines are, simplistically, engineered water
ecosystems which use natur
al elements such as sunlight, plants and animals to break down toxins,
concentrate metals and treat organic material in sewage and waste water.
Living machines can be part of clean, simple, economical and environmentally
viable solutions to a number of problems.  They offer less costly alternatives
for municipalities planning to spend billions of taxpayers; dollars on
expansions and new sewage a
nd water treatmen systems.  They do not use chlorine
