Isn't yield relative? Take a bell pepper for instance, perhaps one grown in x soil another in y, the nutrient contents will vary even if one is clonal.
There have been some rumblings about the nutrient qualities of certain food goods. You also hear about European vs. American vs. garden-grown in terms of qualitative differences. I've even seen it quantitated, indeed there was a documentary surrounding this [0]. There's a researcher that took historical records of micronutrient measures and compared them against modern cultivars, finding a decline in the per-volume contents.
I think it begs several questions about modern practices in agriculture beyond increased volume yield which is too often in the limelight. It just reminds me of Pika, which is associated with micronutrient deficiencies.
Thank you for that link. This documentary was interesting for 3 reasons: A) clarifying that the seeds of all produce we eat comes from 5 international companies, 4 of which also have pesticides as a main product; B) child labour enables prices per kilo seeds of 400k (!) C) journalism that really confronts CEOs with uncomfortable questions is possible. And it introduced me to kokopelli which is where my future seeds will come from.
