[compost_tea] Chelated micronutrient sprays.



Hi Elaine,

What you have said makes sense, but that doesn't address what I found being
stated by the State of Washington.  What I found was if an organic grower
wanted to put chelated micronutrient sprays on their plants and soils then
that grower had to first do plant tissue tests or soil tests to demonstrate
if there was a deficiency before they could apply chelated minerals on their
plants or soils.  And as you have said, compost teas are chuck full of
chelated minerals.  That makes CT's a form of chelated micronutrient spray.
The WSDA is saying chelated micronutrient sprays CAN be used BUT soil and/or
plant tissue tests are required first.

Here's the first part of the quote from what Washington State is saying on
the "WSDA Generic Materials List
Crop Production":

(26) Chelates. Chelated micronutrient sprays may be used in conjunction with
soil and/or plant tissue tests.

I've cc'd this to organic@agr.wa.gov .  Perhaps someone there can provide an
answer back with regard to how this applies to compost teas for organic
growers in Washington State, since compost teas are chuck full of chelated
micronutrients?

Sorry I'm behind in getting back to the list serve and these questions.  I
just got the April e-zine off, and some of these things are addressed in
there.

For example, several solid statements about what is allowed in the NOP rules
about compost tea.  As I sent to the list several months ago, after
discussions all around with many poeple, including OMRI folk who have been
great working on this issue, compost tea is allowed without restriction
under the NOP regs, EXCEPT all ingredients you put into the tea has to be
approved by a certifying agency, like OMRI.

Now, to Thomas' question.  Don't mis-interpret the organic regs.  The regs
do not say you cannot have chelated minerals in organic materials.

The regs say you can't use chelated mineral PRODUCTS.  Why?  Because of the
process by which they are made.

We'd be in deep trouble in the world of compost if you couldn't use chelated
minerals in organic production, because compost is chock full of them.

So, presence of chelated materials is of no concern.  It is if you make
chelated mineral products, they have to be made without strong bases or
acids, no non-approved organic materials can be used to make the chelates.
No preservatives not allowed by the certifying agencies either.

OK?

So, this might be a good question for Dr. Ingham, can it be guaranteed that
a properly brewed CT will not have any chelated minerals present in that
tea?  If that can not be guaranteed, the Organic Growers in Washington State
could be at risk of loosing their organic certification if they use CT
without first doing tissue or soil tests.

Another question, If humus material is used in CT, or even worm castings,
can it be guaranteed that CT will not contain chelated minerals?  i.e.,
humic, or fulvic acids and minerals?
