How about a "crops genetic potential" in terms of "crop nutritional
quality", as function of an evolutionary (biological) vs.
manipulated genetic construction.

To have any meaning, a "generalized contrast of production systems
such as conventional vs. organic" must necessarily be founded on data
relating to "these [and other relevant] types of relationships".
(Other relevant relationships include organism level - rather than
biosphere level interactions and efficiencies, given that a higher
level organism itself constitutes an environment integrating distinct
processes which some believe have evolved from discrete origins).

I would add that in addition to any "insights on the impact of
multi-species interactions", I have placed a standing call for data
relating to "crop content of nutritional components such as calories,
protein, lipids, vitamins, phytochemicals or minerals", and/or
physiological differences in "Seedling Fruit Trees vs. Fruit Trees Not
On Their Own Roots, and/or the performance of organisms feed one or
the other as a staple diet.

This post is also meant to serve as a reminder that these studies have
yet to be carried out, in spite of the ubiquitous presence of the
latter in industrialized present day agriculture.

(Why not do it now at Tufts)?
