There seems to be some common ground (even if soil is in dispute!) on high yield dilution though. The abstract states: Contemporaneous analyses of modern versus old crop varieties grown side-by-side, and archived samples, show lower mineral concentrations in varieties bred for higher yields where increased carbohydrate is not accompanied by proportional increases in minerals – a “dilution effect”.
