Compost tea is hogwash. Just plain old compost would be much better.


So Travis another one of your silly one liners....

You and Paggers are welcome to your silly opinions, bsed on no
experience....

For those with open minds...

Part I:

The following is a selection of recent science
papers and on-farm test results on compost teas,
composts, soil microbial diversity, biorationals,
and disease-suppressive composts posted
to the Compost Tea List on Yahoo!Groups.

Principles and prospects for plant disease control (Literature
review). Compost Science & Utilization. Vol. 10, No. 4.
(Autumn) p. 313 - 338.

This is the literature review published in Compost
Science & Utilization by Steve Scheuerell and Walter
Mahaffee of Oregon State University. It was part of
Scheuerell's PhD disseration on compost teas. This is
the most thorough and extensive literature review on
compost teas published to date.

Compost Science & Utilization is a journal published by
JG Press, Inc., which also publishes BioCycle, the trade
magazine of the composting industry.

Archived articles in JG Press publications are available
online for 3 each.

Organic Teas from Composts and Manures
Richard Merrill, OFRF Grant Report 97–40
http://www.ofrf.org/publications/Gra...ports/97.40.10
..Merrill.Fall97.IB9.pdf

An Organic Farming Research Foundation report. This is the
full OFRF report; a 51-page PDF download, with 88 literature
references in the bibliography, "Selected References for
Organic Tea Extract Studies."

This OFRF research report is based on work at Cabrillo
Community College.

It has noteworthy background information on compost teas and
the composting process. It provides an interesting explanation
of the Four Paths of Organic Decay.

Of special interest, is the prototype homemade aerobic compost
tea extractor, based on a double barrel design.

These PDF papers are 4-6 pages each. They summarize on-farm
research into compost teas, funded by the Energy and
Sustainable Agriculture Program at the Minnesota Department
of Agriculture. They provide insight into compost tea
preparation, microbial analysis, and compost tea use on
the farm, with a summary of results.

Compost Tea Brewer Test Results
North Country Organics
www.norganics.com/tests.html
www.norganics.com/Test7-17.pdf

Paul Sachs at North Country Organics, author of Edaphos:
Dynamics of a Natural Soil System and Handbook of Successful
Ecological Lawn Care, conducted a series of compost tea
brewing trials. This Web site hosts the SFI microbial
analysis reports from these trials. The parameters for
each batch of compost tea are noted with each lab report.
The parameters included volume of tea, brewing time, aeration
time, water temperature, and the use of three compost tea
additives known as Fungal Booster, Bacterial Booster,
and Mineral Booster.

EPM Compost Tea Test Results from SFI
www.composttea.com/test_results.htm

Bruce Elliott at EPM, Inc. in Cottage Grove, Oregon,
manufactures the Earth Tea Brewer. This Web site hosts
SFI microbial analysis reports for compost teas brewed
with EPM's 22-, 100-, and 500-gallon Earth Tea Brewers.
