This good information from agro-forester supreme, Mark Shepard, who once worked extensively with simple vegetable growers:
I've brokered produce for nearly a hundred certified organic growers since 1995 and every single one of them who has ever used the Albrecht system have outproduced anyone who has not. As far as east-coast applicability is concerned,... In ammending some New England, granite-derived soil according to Albrecht's numbers the results have been astonishing to the point where the results seemed like divine intervention. (one of the plots was on a property that has received the preps since the early 70's) Nay-saying the method by those who haven't tried it (or who haven't followed the recommendations completely, perhaps because they thought they couldn't afford all the rocks) is empty air. Spend the bucks. Buy the rocks. (they last a LONG time) The effects will amaze you and feed you well for years. (I'll have to relate my asparagus "trial" to you some day) -- Mark L Shepard Consulting Agroforester Forest Agriculture Enterprises 608-627-TREE
