I agree, Tad. I would think there is less diversity in a longer brew. It al=
l depends on the context of your approach. To put it simply, those looking =
to establish soil food webs batch brew. Those looking for something they ca=
nnot buy off a shelf with more "plant food" brew perpetually. That's how I =
think about it anyway.
I just had a conversation with a microbiologist from our local University. =
He happened to be in the parking lot when I showed up for work waiting to p=
ick up his wife's CSA share. I have talked with him several times in the pa=
st and we have made plans to work together. His past emphasis was on E.coli=
and he is now moving into fungi. They have identified a new species of fun=
gi that is found in concetrations of 10,000 micrograms per gram, much highe=
r than normal species in healthy conditions. I didn't have time to fully en=
gage him, but he said to me verbally without understanding everything he wa=
s saying to me that they could measure biological strength of organisms.
Does anyone have any thoughts or ideas on how this could be done?
