Re: [GWL]: A New Rant

Some of these might need to be qualified, it seems to me.  
For example, #11.  In established forests the soil is often acidic due to
the presence of mycorrhizal fungi mats which release organic acids as a
means of making minerals available.  The soil without the fungi might be
neutral or alkaline, but the presence of the fungi makes it acid.
Similarly, the use of oak (or other leaves that increase the humus content
of the soil) can encourage growth of mycorrhizal fungi and produce the above
effect.  Not a universal condition, but an exception to saying that leaves
DON'T reduce pH.

#15. Using sulfur to reduce soil pH.  Commercial blueberry growers do this
sucessfully, to the extent that if it is done too many times, the soil can
lose it's buffering ability and the pH can suddenly "crash," going too low.
