How are you supplying aeration?
Are you using the rotary pump and a venturi for aeration and pumping the c=
t over over?

Subject: [compost_tea] Rotary Pumps For Brewing
Hi Guys,
Is there antone else compost/microbe brewing with a low pressure high vol=
ume rotary pump set up.
Just reading all the problems with filters and screens,sounds like alot o=
f trauma.We use a presreened inoculi[27 depending on what we want as far as=
ratios and diversity]This is then added to the pre aerated and warmed wate=
r with the apprpriate food.
Brewed for 12-24hrs and then pumped into the sprayer and off we go[no fil=
tering or screening]
We are doing 12000ltrs/day and are predominately apply to Dairy Farms or =
Kiwifruit Orchard.
The SFI results are more than adequate with Fungi counts of 60[if require=
d]
The criticism we initially got was the brewing system was too vigorous bu=
t the lab results and more importantly the on farm results speak for themse=
lves.
Our key dairy farm operation has not used nitrogen for 3yrs now and the f=
arm gross margin was raised $85000 last year[or$1000/ha].During the Autumn =
dry spell the farmer had people stopping off the road and asking what they =
were doing so different,as all the farms were drying out around them and th=
is placed just stayed green!!
As we brew in 4000ltr tanks[need to,to cover the farms were treating and =
economics]the idea of filters and screens is not practical[and a pain],due =
to the fact that when we deal with commercial spray contractors we need to =
cover 40-60ha/day to be economic.
Does anyone else brew this way?
