I've never worked at a megacorp farm, but my observation is that the majority of farmers aren't thinking like this. Granted it might be different because the crops around me which are most commonly grown are wheat, barley, and hay. IDK the effects of soybeans/corn on soil and it's possible they have a much more pronounced effect. For wheat, barley, hay, most the farmers I know will plant it YoY and use fertilizer to counteract soil deficiencies.

Crop rotation, AFAIK, is mostly employed to reduce the need for fertilizer.

It definitely is a problem because farmers tend to over-fertilize which can cause nasty problems the runoff water.

I also expect this will likely become something a lot more farmers start to practice as fertilizer prices spike.

What works is very regional.
