Compost Tea [part 4] – Basic Tea – Compost Only


Welcome to the Grok Shop and part four
in my compost tea series. In this video I’ll be doing a basic brew which is
compost only with no additional additives and we’ll be thinking of this
as a kind of reference brew for the other brews we’ll be doing. And in
addition to the actual brewing, I’ll be showing a qualitative analysis or assay
that I do through a compound microscope. So, quick reminder of the objective of the
compost tea brewing process is to extract and multiply microorganisms that
come from the compost itself. Umm, this little nematode which survived
the brewing process is not a good example of that. They do not multiply in
compost tea like bacteria and archaea or archaea but it’s just kind of fun to
look at. So here I have some compost left
from doing some potting; about a week prior this was extracted from the
compost heap. You can see it’s got a little bit of fungi growing on top which
is which is great; it’s not really necessarily something that’s part of
this video (trying to produce fungi), but if it’s in there that’s fine and
it’s it’s pretty normal to have fungal hyphae mycelium as part of your compost
anyway. So how much compost to use? I usually use about four cups; I’ve seen
anything from two to six cups per five-gallon bucket of dechlorinated
water recommended. So I typically stick around the four cup area. This is a
measuring cup but it’s also just a convenient cup to use I don’t really I
don’t I don’t stick to exactly four cups necessarily but just ballpark range. So now if you’ve been following along
you will have seen part three in my series where I discuss water dechlorination and
of course how important that is for these microorganisms to have a safe
environment to flourish in and one of the techniques I showed was you can use
humic acid and I’ve actually done that here. I’ve dechlorinated outside a bit
and there was still some chlorine so I added a bit of humic acid so you’ll see
my water looks a little brown. Now you know some people say humic acid can
have a detrimental or negative effect on the microorganisms. I’m not so sure
especially in really small quantities. But anyway we’ll see in the analysis
that I do how everything works out so right off the bat we can see some
fungal hyphae here which is really covered in bacteria looks like they’re
they’re chowing down on that – pretty good and those flickering dots there are
gonna be flagella it looks like we got several of those and this view folks I
do apologize for the fuzzy view we have here it’s uh due to the poor quality
camera I have at this point for microscopy hopefully in the future we’ll
have a little better a hookup for y’all and get some better views but it’s it’s
good enough to get a general idea of the biodiversity we have going on here
anyway all right this looks like we have possibly another flagella a larger one
maybe this could be an eclair eeeh rubbery which is an amoeba that
transforms into a flagella and it would be in the flagella state here and they
do that when they run out of food which is bacteria for them but he’s being
pursued looks like by another one or two smaller flagellants so clearly this compost he does have
life it does seem to be fairly sparse compared to some of the other assays
I’ve done on other brews but I guess that’s not super surprising since we
didn’t provide any food for the bacteria to expand and multiply kind of a nice shimmering flagellant
there recognize this nematode it’s the same one from earlier in the video that
we saw and dark field view I’ve just got him under the bright field view now so
again this was really more of a reference brew and it really wasn’t
expected to produce huge amounts of biodiversity but there was some activity
and I was pleased with that and then as you may have ascertained this is not a
quantitative analysis it’s just strictly qualitative but we’ll be doing more of
these qualitative analysis assays for future Bruce that’s how it’s done
thanks for watching
