Here is something one of our gardeners came up with years ago...I am not
sure how this will transfer on text email but if you really want a clean
copy I have it in a word document.
Happy New Year Everyone!

The Science & Engineering section on the Cornell Composting webpages
has a
discussion of C/N ratios that includes links to the list in the
publication
"On-Farm Composting Handbook" with N and C/N values for many materials,
as
well as a link to a table of lignin that also includes N and Ash
values. It
also provides formula to teach you how to calculate C/N values
yourself
http://compost.css.cornell.edu/calc/cn_ratio.html
Klickitat County (Washington) has an interesting compost mix calculator
with
nutrient data and invites users to contribute data obtained from test
samples they submit to the laboratory at Washington St. University, but
the
current list hasn't yet grown even as large as the Rodale '79 list

Hope this helps! Chip

Subject: [cg] NPK values for various compost materials
I'm looking for a longer list of nutrient values for various compost
materials. I've got a good start with the 1979 Rodale composting book,
and
looking for items in addition to that list. Does anyone know of a book
with
a longer list or a website that people keep adding info to?
Thank you!
Sharon
