Thanks for that information. It's very interesting. Somehow I can't find more detailed online resources. Do you have them? I'd like to know the details of the the study.

Edit: I found some additional information, maybe this is about the research:
A study conducted at Rutgers University (Bear et al., 1948) is frequently misquoted as evidence supporting the position that organically grown vegetables are significantly superior in minerals and trace elements to conventionally grown vegetables. In reviewing the original publication, one can clearly see that this was not the intention of the study nor does it give support to this premise.
