Subject: [NAFEX] gypsum / sheetrock

A fellow orchardist uses sheetrock (gypsum board ) to both add gypsum and
smother sod and
kill weeds around new trees. Since we are on heavy clay I reckon gypsum is a
good idea,
and I am sure I could access sheetrock cuttoffs by the truckload from local
contractors.
My only concern is what is in the product besides gypsum - as I may start the
process of
organic certification soon. Paper, glue and gypsum sounds pretty innocuous,
anybody know
if there is any objectionable stuff in sheetrock? Other commnentary? Del
