Re: RES: [compost_tea] Nutritional effects



Hi Elaine
Thanks for your previous info on the lime sulphur.

I think its not so much " detrimental" as contrary to our purpose for the
plant at that time. If you hit a plant with a strong dose of growth energy
when it is in the fruiting phase (head initiation of grains - that 38 to 42
day stage, or early flowering - the bolting stage - of canola)  you can
easily cause a reduction in yield - and likely will. I've done that with
canola as an experiment. But the plants will tell you - they will respond to
that nutrient input with a reduced brix reading - probably minus 3 or 4 over
control.
Your plant nutrition friends in the universities will probably react with
either blank stares or outright hostility when you ask about this stuff,
they will tell you its garbage, just as their friends probably tell them
that you are nuts with this compost tea thing. As Arden would say its
outside of their paradigm.
Up until a few short years ago ask any conventionally trained crop
agronomist or ag science researcher about foliar nutrition and they would
tell you its a waste of money - does not work - yet these same guys have
been flogging us foliar applied chemicals for decades and the science that
proved foliar worked was done by your own atomic energy commission in 1953.
Only when the sheer weight of numbers of farmers doing this successfully
became just too much to ignore any longer did they consider it.

Can you please elaborate on this bit ? When would a nutrient induced brix
increase be detrimental? or have I misread this ? ( I'm talking normal
growing conditions - decent moisture and active plant growth)

Is it within your paradigm that its possible to influence this - negatively
and positively - with foliar nutrition?
If yes then its a possibility (maybe unlikely but a possibility none the
less) with CT
If No then I guess I better go bang my head on a wall
