In March of 1997 I had a soil analysis done with the results sent to a
Agricultural Laboratory.  It came back with specific comments on how to
maintain my soil for optimun results.  Here is a footnote to those
comments:

Boron: Confirm low levels through tissue analysis.  BEWARE of the danger
of over-application of boron.  follow label directions carefully.

Another note was: ORGANIC MATTER levels maintained above 2.0 percent
will provide an improved soil structure and a more sustained release of
nutrients.
