Corn and soybeans are most definitely rotated. Peanuts are a common nitrogen fixer and Alfalfa is great too.

>This crop rotation benefits both alfalfa and wheat/barley/corn. On the one hand, cereals tend to decrease the development of weeds, leaving the field free for the alfalfa cultivation. On the other hand, there are findings suggesting that corn following alfalfa yields approximately 10% more than corn following corn.[1]

Peanuts increase nitrogen and probably no nothing for micronutrients. They may allow time for the underlying rock to transfer minerals to the soil which are consumed more heavily by the opposing crops, but they probably won't do anything for the issue reported in TFA.

Having more corn doesn't mean that the corn or soil has more micronutrients. Corn is nitrogen heavy, so rotation makes sense if yields are all you care about.
