Re: [compost_tea] (Cryptic post)
Hi Dan -
Just like Jeff Lowenfels, you went to the source and checked out the original information and came to the same conclusion I did.
I think you deserve a free SFI sample as well as Jeff. I'll send a certificate.

Elaine,
I checked the PTO website and found the patent application (excerpted
below). I appears that Growing Solutions is attempting to patent the CT
process for their brewer. Of course it is broad enough to cover every
CT brewer out there.
Happy Holidays,
Dan

Compost tea system
Abstract
A compost tea system uses a water-holding tank for containing process
water. Compost is immersed into the water in the tank in baskets
defining a filter media. Air is pumped into membrane disk diffuser
modules in the tank and the liquid is sparged with fine bubbles to
thoroughly agitate the liquid, extract nutrients and microorganisms from
the compost, and to ensure a high concentration of dissolved oxygen in
the liquid. The high level of oxygen selects for desired aerobic
organisms to produce a rich compost tea. The finished tea is drained out
of the tank and the tank and its components are easily cleaned and
sanitized.
