Re: [compost_tea] Plant Teas Experiment
Further to my plant tea experiment - on the 10th day of aerating the 50 g=
allons of plant tea, the D O rose to 6 ppm and I reckoned it was going to b=
e OK to add to the 200 gallons of CT. BUT on the night of the full moon the=
wind was blowing so strongly I decided to apply it the following night. On=
the 11 th day the plant tea D O rose to 7.1 ppm and it had a lovely sweet =
smell.
I added it to the 200 gallons of CT ( D O of 8 ppm after 3 days od brewin=
g) and then added 2 gallons of molasses and 2 gal of a blend of fish, seawe=
ed and fulvic acid and then pressed the button. Somehow the gremlins got in=
to my big irrigation pump and it decided to operate at about 50% power so I=
switched it off.
As you can imagine the CT mixture went horribly anaerobic very quickly. I=
aded more aeration to the tank and it has a D O of 4.5 ppm at the moment.=

What I really would like to know is this - what are the quantities of the=

But I guess such testing would be very expensive so I would just have to a=

ELAINE - Re the microbes in the plant tea - wouldn't they be predominatly=

in the short time the two would be mixed together just prior to being appli=
