Having recently visited a local agricultural research institute with some
Tanzanian visitors whose crops were failing more and more often, I can attest
to
that!
They were using Lake Victoria as their water source. The lake is very
slightly
salty. Over the years, the salt has remained in the ground while the water
has
evaporated or been "used" by the plants. The soil is now "dead" and
"unlikely to recover in less than a few thousand years, if at all". And that
wasn't large quantities of salt all at once, but a very small amount spread
over
a lng time.
Don't do it! Copper radials are more effective and a lot kinder on the
environment.
