---Thanks Paul.  There is some difference though, between the
samples.  I have to go back to conversion tables to get
micrograms/mls to bacteria/ml and I'd GUESS 8.1 micrograms/mls is a
bunch of bacteria in 300 gallons finished product or more importantly
in the 15-25 gallons applied/acre..Being familiar with only standard
plating techniques I haven't been able to discern how  SFI
differentiates active and total but am eagerly waiting to learn.
Thanks again though.  I can't help but notice some of your samples
total bacteria are in thousands(ug/ml) while others are in hundreds.
Did you post differences between recipes,procedures, etc of samples?
And also I notice all your samples are well into the desired range,
if not way beyond!  That's gotta be exciting.  Dennis
