Whoa! This is such a poorly designed experiment. Someone should point them
to the Harvard University project. Peter I think your spot on in your
observations. I'm amazed that this comes from Yale. You would think they
would talk to Todd Harrington or Bill Skerritt or another expert in their
area.

Subject: [compost_tea] Compost Tea 'Data' from Yale
Hi folks;
I just came across a published paper entitled "Closing the Loop: Alternative
Land Management at Yale". The paper's root is located at
http://environment.yale.edu/hixon/student-research/student-research-interns/
The paper is located here;
http://environment.yale.edu/hixon/files/pdf/2010_Emily_Stevenson.pdf
Does anyone else find this paper a bit shocking? Here's another case of
flawed methodology and misunderstanding on how biological systems perform in
the real world.
There seems to be a complete disconnect on how compost tea is made.
* Too many foods (certainly an anerobic tea they're referencing here)
* No testing of compost tea
* No mention of brewer design aside from a 'bubbler'
* No DO data
No testing on their 'food waste' compost.
No mention of microscopy...at all.
Flawed methodology in before/after soil testing. Only bacteria are measured
using narrow range of foods. Where's the data on fungi, nematodes and
prots??
There's a misunderstanding of organic matter accumulation in soils. Can we
expect appreciable increase in OM using 1,500 grams of compost, making tea,
diluting 1:1 and applying multiple times in a 6 X 6 meter area?
There's a major disconnect as to how to apply CT on a large scale and even
the basics of equipment involved. It reads as though they're quite resistant
to changing there current chemical system.
I see lots of logarythmic scatter gram but not much in the way of science.
I'd expect to see somthing more substantial. This is a dissapointment from
an institution as fine as Yale.
