It needs to create biomass from something.
- PeterisP 5y agoThe main content of plant-created biomass comes from atmospheric CO2 and water, not from soil (well, roots extract water from the soil, but that's not what we mean by soil depletion). A significant minority is nitrogen, which either needs nitrogen-fixing plants (which extract it from atmosphere) or fertilization.

And it is speculated that it is because of soil depletion. https://www.cookinglight.com/eating-smart/nutrition-101/fruits-vegetables-less-nutritious-now https://www.cookinglight.com/eating-smart/nutrition-101/frui...
