What evidence do you use to make the statement you made in your post about =
water temps for brewing -
Hi Elaine:
I started examining soil tests after applying tea brewed at higher temps an=
d applied at soil temps 10 D F or more below the brewer temp. When I brewe=
d closer to the soil temp, my soil test came back actually showing the tea =
was having some beneficial effect. The warmer tea didn't test as well. My=
assumption is that soil temperature is important when applying biology tha=
t has to work in the soil. I started doing some research into soil microbi=
ology and temperature and found that different bacteria were found at diffe=
rent times and the amounts and types seemed to be dependent on soil temp. =
I have tried brewing at temps from 80 D.F. down to 55 D.F. and I have been =
looking at the tea with a Spencer 1000x microscope. I then take soil sampl=
es at different times and examine them the same way after dilution in disti=
lled water. I try to make sure the amounts of soil and soil depth are as s=
imilar as I can get them and I use the same microscope technique every time=
. I look to see if what I am transferring from the tea is "taking" in the =
places I apply it. Because of the limits of my microscope, I can't tell ty=
pes fo bacteria but can see bacterial fields and I can see if the same orga=
nisms transfer to the soil. This, of course, means before and after soil e=
xamination.
>From these results, I came to conclude that brewing closer to soil temp gav=
e me a greater assurance that I would be promoting biology that was more in=
line with the temperature rather than brewing for one temperature and hopi=
ng I was getting the correct microbes for the soil.
By the way, I have been experimenting with the aerobe/anaerobe balance and =
the growth of protoza. I am getting results and will forward those when I =
have some repeatable trends. Your comment about Bacillus Licheniformis dur=
ing the mad cow discussions got me looking into ways to grow protoza and ba=
cterial/fungal eating nematodes within a brewing cycle of 48 to 72 hours. =
That meant that I had to rethink how I was brewing while still keeping the =
basic concept of ACT in place.
That is one of the experiments I am involved with. I have four others that=
test my own understanding of the process and time lines for microbial grow=
th. I'm basically trying to get to the Trophic Zone that contains Flagella=
tes, Ameoba, Paramecium and BacterialFungal eating nematodes, etc. So I hav=
e brewers constantly going with different inputs. In one, I have an experi=
ment to produce actinomycetes I gathered up from the local decomposing tree=
detrius. (I take a lot of precautions here because research has shown me t=
hat certain strains of these things can be quite toxic to humans.) I have =
trained my son, a ten-year-old home schooled intelectual monster in the sam=
e microscope technique and logging method I use and he is starting to do th=
e sampling now.
I have been looking at bacterial growth, bacterial enzymes and the cultivat=
ion of higher order bacteria/fungi through enzymes produced by the critters=
. I have already grown protoza and nematodes in brewers by using hay mixed=
with compost and molasses and blood meal with some other organic inputs. =
I'm not a scientist by education but I'm not ignorant of the scientific met=
hod and the need to document before writing or speaking. I learned this ea=
rly on when I misstated that ACT can help control snails and slugs. It was=
a good lesson in humility. If I write something on this list, it is the r=
esult of over two years of experimentation and brewing and applying tea in =
"real world" situations. I am constantly experimenting and testing my own =
hypotheses and those I implement from other people. It is simply a fact of=
this type of business. Where I live, my business associate and myself are=
considered knowledgable in this stuff because everything we have stated, w=
e have proven. Every assumption we have made has been backed by prior know=
ledge and shown to work. I do all the brewing and experimentation and brew=
er/aerator design. Very soon, I will have my designs posted so anyone can =
build the systems from off-the-shelf materials and be sure that they are as=
sembling a brewer that will work as stated.
However, if I misstate something or find that I had an incorrect conceptual=
model, I will freely admit it and correct my misstatement.
