[GSBN] Suitablity of fresh cowdung supplies from feedlots for natural plasters

[forum at lamaisonenpaille.com]

Hello Andy,

I would like to receive your pdf on your traditional plaster.
I only once used cow manure (in India) and was very happy with the 
result. But they were very free roaming indian cows ;-)

Bye,
