Just from observing what "real" farmers do...
They usually rotate beans (which are nitrogen producers) with corn (nitrogen user). Weed/grass issues can become a problem if nitrogen producers aren't rotated out to a nitrogen user.
I have seen farms that grow beans on the same fields every year, so it can be done, but it's probably a good idea to use up the N occasionally.

Here is some info I found yesterday (in between food comas) about year after year beans. It is even about a farmer who is about 125 mile from me. I am going to go to year round beans. From what I have witnessed from my corn vs bean usage with rye over-seeded, the beans are utilized later i the season, last into Feb, March and offer more nutritional value than corn. I have a very high deer density and my corn plots hardly make it to and never through December. I have 5 acres of beans in two plots.

I live right at the edge of heavy ag. The Missouri river bluffs are what I border up to with ag almost nonexistent towards the river(about a mile and a half) but ag is king starting at my property, heading west.

You would think that like clover nitrogen would build up in the soil and then grasses would become a problem.

I have guys planting beans on beans for 25 years or more. And I have guys planting corn on corn for the same. Until a soil born pathogen of some type develops because of beans on beans, and cuts the yields down to nothing, farmers will continue to do it.

One thing about corn on corn is, you get slightly reduced yields when you first start out doing corn on corn. Then after about 4 years the yield seems to come right back. The problem is the cut worms, root worms and everything else stay around also.
