Dear John:
I've located information on research that was done several years ago by
the Agricultural Research Service on using scrap gypsum wallboard as a
soil amendment. The web references to this research are provided
below:
http://www.barc.usda.gov/psi/korcak/rk-gyp-o.htm
http://www.ars.usda.gov/is/cgi-bin/ffp.pl/is/np/agbyproducts/agbycontents.htm?gypsum
and composting#first_hit
In addition, I have provided the web address for the Gypsum Association,
which funded this research, for further follow-up.
http://www.gypsum.org/main.html
If you received information on other beneficial uses of scrap gypsum
wallboard as a result of your query I would appreciate it if it can be
posted online.
Sincerely,
Roger M. Guttentag
