I seem to remember reading of a study which showed that at least the
alkaloid pesticides in many food plants (fruits spring to mind) are
elevated in organically grown plants due to the higher pest load they
have to deal with.

See how tender trees raised in protected allotments get hammered by
rabbits when put out. Given a few seasons in the weather they are much
more able to tough it out.


Huh? Older trees (or at least the parts of older trees that a
rabbit can reach) seem to be much less palatable to rabbits
than younger trees, but what has this to do with 'protected
allotments' and how on earth do you think that a tree can
ever 'tough it out' against rabbit incisors?
