Subject: Organic quality refs (was Re: desk study needs your help - fwd)

Dear Ineke, Romero and other possibly interested BD & Sustag friends,

I have some quite good and clear refs showing significant quality 
differences between BD, Organic & Agrochemical produce, besides my 
own research results - I will fwd you an abstract in the next msg 
(not to the lists, where I've already posted them).

Many of these refs are only in German. Please note that Koepf's 1976 
English translation of BD Agric. DOES NOT include some essential
data from quality research (Samaras, etc) that appears in recent editions 
(German & Portuguese).

I include below both the positive and negative/critical papers, to give the 
whole picture:

Hello Ineke:

As a nutritionist I have being looking for such evidence, but with little luck.

I do not think that we will be able to find much differences between
conventional and organic or BD foods by using the limited observation
instruments available to positivist science (reductionist view).

Nevertheless, in the New Ground section of the sept-oct 1996 issue of
Organic Gardening  (Rodale Press), the editors mentioned a study conducted
at the Swiss Federal Institute of Technology in Zurich and published in
"Plant and Soil 167:305-311, 1994, where the authors found twice the amount
of B12 vitamin in crops treated with manure than in crops grown on soil
treated with pure B12.

Vit B12 is not commonly available (from a human nutrition point of view) in
vegetable sources, therefore this finding might be a breaktrough to explain
why the modern vegetarian diets are normally deficient in this nutrient.

Hope this is usefull and please share with me the results of your research;
i am specially interested.

Best of luck.
