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

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!
