[compost_tea] Re: ACT



---Dave, I was trying to point out there are many variables included 
even in the testing, even of objective tests. I run a flour sample 
here (myself) and do all the sample prep one day and do it again the 
next day and get different numbers (vitamins B1 and B2 for instance)
each day. New variables the next day? Sample changed? Usually the 
numbers are close but what do you do when it comes time for 
disposition esp when numbers are not close? Maybe average, maybe 
rerun sample, maybe get another sample? Maybe re-write the specs.? 
Maybe throw out one for some reason. Anyway experimental design will 
be important in the brewer tests. Dennis

need for testing in my mind, not with someones hard found recipe, but 
with a mutually agreed to compost and food of some kind.  Unless we 
can get information about the variability of these machines then 
we're all on our own a bit and progress, much needed, will be 
difficult.  It's hard to extrapolate to new situations unless we nail 
down the variables one at a time.  I think the strength of this forum 
is found in combining our sometimes expensive experiences.  I've 
spent a couple thousand on testing myself without any product except 
that I teach.  Those of us in the non-commercial world stand to gain 
the most from sharing.  If I can pay for only one report and get the 
answers from 5-10 others I'd consider it money well spent.
