I don't follow, forests are great but if the farmland you are using gets ruined you need to do something... right now something is usually more petro-fertilizer and pesticides, and occasionally more traditional methods at smaller scales.

It's great if you can use less land for farming, but if concentration leads to the land being damaged beyond repair then what's the point? You'd just have to turn unused land into farmland, and if you're doing that you may as well use crop rotation intentionally.

If you need to deposit massive amounts of natural gas (used to make hydrogen used to make ammonia) on a small amount of land instead of using a larger amount of land and using slower methods to get nitrogen in the soil... there is surely a stable point where the soil is continually usable without needing a lot of fertilizer.

Yes, it seems to me increased efficiency would best be spent on fallowing the fields to allow the soil to regenerate.
