Hi to you, Saw your posting on the newsgroup. Please let us know about your workshop. We have a web page where we are trying to keep all US permaculture related courses current. Check it out at http://www.jumpnet.com/users/perma My two favorite of Elliot Coleman's books, both of which have soil mixes if memory servers correctly are "4 Season Harvest" and "The New Organic Farmer".
